firmware: psci: Fix return value from psci_system_suspend()
Currently we return the value from invoke_psci_fn() directly as return
value from psci_system_suspend(). It is wrong to send the PSCI interface
return value directly. psci_to_linux_errno() provide the mapping from
PSCI return value to the one that can be returned to the callers within
the kernel.
Use psci_to_linux_errno() to convert and return the correct value from
psci_system_suspend().

efi/x86: Free EFI memory map only when installing a new one.
The logic in __efi_memmap_init() is shared between two different
execution flows:
- mapping the EFI memory map early or late into the kernel VA space, so
that its entries can be accessed;
- the x86 specific cloning of the EFI memory map in order to insert new
entries that are created as a result of making a memory reservation
via a call to efi_mem_reserve().
In the former case, the underlying memory containing the kernel's view
of the EFI memory map (which may be heavily modified by the kernel
itself on x86) is not modified at all, and the only thing that changes
is the virtual mapping of this memory, which is different between early
and late boot.
In the latter case, an entirely new allocation is created that carries a
new, updated version of the kernel's view of the EFI memory map. When
installing this new version, the old version will no longer be
referenced, and if the memory was allocated by the kernel, it will leak
unless it gets freed.
The logic that implements this freeing currently lives on the code path
that is shared between these two use cases, but it should only apply to
the latter. So move it to the correct spot.
While at it, drop the dummy definition for non-x86 architectures, as
that is no longer needed.

firmware: arm_scmi: Add support for platform to agent channel completion
On some systems the SCMI platform to agent(p2a) communication can be fully interrupt driven. The notification(p2a) channel needs completion interrupt to drive its notification queue at the platform. Without it, the platform notification will not work as the platform will wait for agent indication of clearing the channel via interrupt unlike few platforms which can poll instead. To support such systems, an optional unidirectional mailbox channel for p2a reply communication. If the platform sets channel INTR flag set indicating that it expects the agent to trigger the interrupt to acknowledge the reciept of the notification or any p2a message, and the completion interrupt channel is provided, send a mailbox message to the platform after the p2a message is read and channel is freed to accept new notifications or p2a messages.

firmware: arm_scmi: Add support for system suspend in power control driver
SCMI supports system suspend notification from the platform. The suuport for the same can be added in SCMI power control driver. However, currently there is no way to pass suspend level to pm_suspend() call from this driver, so use suspend-to-ram(S2R) will be used. Couple of things to note: 1) The userspace can still configure whatever default behaviour expected for S2R. 2) The userspace needs to keep the wakeup source enabled, otherwise the system may never resume back.

firmware: microchip: support writing bitstream info to flash
Updating the FPGA image might bring with it changes visible to Linux, so it is helpful to also co-locate dt-overlays that describe the new image contents. If these are packaged in a specific format [1] (detected by first 4 bytes being MCHP, since FPGA images have no magic), load the file to the reserved 1 MiB region immediately after the directory in flash. The Beagle-V Fire's "gateware" already creates these files and puts them in flash [2].

efi: Add missing __nocfi annotations to runtime wrappers
The EFI runtime wrappers are a sandbox for calling into EFI runtime
services, which are invoked using indirect calls. When running with kCFI
enabled, the compiler will require the target of any indirect call to be
type annotated.
Given that the EFI runtime services prototypes and calling convention
are governed by the EFI spec, not the Linux kernel, adding such type
annotations for firmware routines is infeasible, and so the compiler
must be informed that prototype validation should be omitted.
Add the __nocfi annotation at the appropriate places in the EFI runtime
wrapper code to achieve this.
Note that this currently only affects 32-bit ARM, given that other
architectures that support both kCFI and EFI use an asm wrapper to call
EFI runtime services, and this hides the indirect call from the
compiler.

LoongArch: Fix entry point in kernel image header
Currently kernel entry in head.S is in DMW address range, firmware is instructed to jump to this address after loading the kernel image. However kernel should not make any assumption on firmware's DMW setting, thus the entry point should be a physical address falls into direct translation region. Fix by converting entry address to physical and amend entry calculation logic in libstub accordingly. BTW, use ABSOLUTE() to calculate variables to make Clang/LLVM happy.

firmware: arm_ffa: Move the FF-A v1.0 NULL UUID workaround to bus notifier
Currently FF-A bus ffa_device_match() handles the workaround for the FF-A v1.0 devices which are not populated with UUID to match. The FF-A bus layer calls into FF-A driver and populates the device UUID if it matches with the driver attempting to match. But this forces to have both FF-A bus and core driver to be bundled into a single module. However, keep it as a single module adds problems for the FF-A driver registrations and their initcall levels. In preparation to split the FF-A bus and the core driver into distinct modules, we need to move the workaround away from the FF-A bus layer. We can add it into the FF-A core driver as a bus notifier. In order to do so, we need to always match any driver with the device if the UUID is NULL and then during the driver binding phase, we can populate the UUID if it matches with the driver UUID table using the bus notifiers. We also need to add a check for NULL UUID before calling the device/driver probe as devices with NULL UUID is possible since we match all for that case.

efi/libstub: zboot.lds: Discard .discard sections
When building ARCH=loongarch defconfig + CONFIG_UNWINDER_ORC=y using LLVM, there is a warning from ld.lld when linking the EFI zboot image due to the use of unreachable() in number() in vsprintf.c: ld.lld: warning: drivers/firmware/efi/libstub/lib.a(vsprintf.stub.o):(.discard.unreachable+0x0): has non-ABS relocation R_LARCH_32_PCREL against symbol '' If the compiler cannot eliminate the default case for any reason, the .discard.unreachable section will remain in the final binary but the entire point of any section prefixed with .discard is that it is only used at compile time, so it can be discarded via /DISCARD/ in a linker script. The asm-generic vmlinux.lds.h includes .discard and .discard.* in the COMMON_DISCARDS macro but that is not used for zboot.lds, as it is not a kernel image linker script. Add .discard and .discard.* to /DISCARD/ in zboot.lds, so that any sections meant to be discarded at link time are not included in the final zboot image. This issue is not specific to LoongArch, it is just the first architecture to select CONFIG_OBJTOOL, which defines annotate_unreachable() as an asm statement to add the .discard.unreachable section, and use the EFI stub.

x86/efistub: Omit physical KASLR when memory reservations exist
The legacy decompressor has elaborate logic to ensure that the randomized physical placement of the decompressed kernel image does not conflict with any memory reservations, including ones specified on the command line using mem=, memmap=, efi_fake_mem= or hugepages=, which are taken into account by the kernel proper at a later stage. When booting in EFI mode, it is the firmware's job to ensure that the chosen range does not conflict with any memory reservations that it knows about, and this is trivially achieved by using the firmware's memory allocation APIs. That leaves reservations specified on the command line, though, which the firmware knows nothing about, as these regions have no other special significance to the platform. Since commit |

sound updates for 6.10-rc1
This one became bigger than usual, not in the total size but rather
containing lots of small changes all over the places. The majority of
changes are about ASoC, especially SOF / Intel stuff, and we see an
interesting work for ASoC DAPM graph visualization, while there are
many other code cleanup and refactoring, too.
Core:
- A deadlock fix at device disconnection
- A new tool dapm-graph for visualising the DAPM state
ASoC:
- Large updates throughout the Intel audio drivers
- Fixes and clarifications for the DAPM documentation
- Cleanups of accessors for driver data, module labelling, and for
constification
- Modernsation and cleanup work in the Mediatek drivers
- Several fixes and features for the DaVinci I2S driver
- New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
Rockchip RK3308 and Texas Instruments PCM6240
HD-audio:
- Cleanup for CONFIG_PM dependencies
- Cirrus HD-audio codec fixes and quirks
Others:
- Series of tree-wide fixes in Makefiles to use *-y
- Additions of missing module descriptions
- Scarlett2 USB mixer enhancements
- A series of legacy emu10k1 fixes and improvements

soc: drivers for 6.10
As usual, these are updates for drivers that are specific to certain
SoCs or firmware running on them. Notable updates include
- The new STMicroelectronics STM32 "firewall" bus driver that is
used to provide a barrier between different parts of an SoC
- Lots of updates for the Qualcomm platform drivers, in particular
SCM, which gets a rewrite of its initialization code
- Firmware driver updates for Arm FF-A notification interrupts
and indirect messaging, SCMI firmware support for pin control
and vendor specific interfaces, and TEE firmware interface
changes across multiple TEE drivers
- A larger cleanup of the Mediatek CMDQ driver and some related bits
- Kconfig changes for riscv drivers to prepare for adding Kanaan
k230 support
- Multiple minor updates for the TI sysc bus driver, memory controllers,
hisilicon hccs and more

soc: devicetree updates for 6.10, part 1
The updates this time are a bit smaller than most times, mainly because
it is not totally dominated by new Qualcomm hardware support. Instead,
we larger than average updates for Rockchips, NXP, Allwinner and TI.
The only two new SoCs this time are both from NXP and are minor variants
of already supported ones.
The updates for aspeed, amlogic and mediatek came a little late, so
I'm saving those for part 2 in a few days if everything turns out fine.
New machines this time contain:
- two Broadcom SoC based wireless routers from Asus
- Five allwinner based consumer devices for gaming, set-top-box and
eboot reader applications
- Three older phones based on Qualcomm chips, plus the more recent
Sony Xperia 1 V
- 14 industrial and embedded boards based on NXP i.MX6, i.MX8,
layerscape and s32g3 SoCs
- six rockchips boards including another handheld game console
and a few single-board computers
On top of these, we have the usual cleanups for dtc warnings and
updates to add more features to already merged machines.

This pull request contains Broadcom ARM-based SoCs Device Tree changes
for 6.10, please pull the following: - Laurent converts the Raspberry Pi firmware DT binding to YAML, updates the firmware driver to use the proper 'struct device' reference for DMA mappings and drops unneeded properties from the DT node and finishes by removing the duplicate firmware-clocks property to bcm2835-rpi.dtsi. He also added support for the CAM1 camera interface regulator. - Uwe adds a pinctrl-based multiplexing description to allow the use of I2C0 pins to allow usage between the 40-pin Raspberry Pi header and the CSI and DSI connectors. He then describes the PCF85063 RTC device available on the CM4 I/O board making use of that pinctrl-based muxing. - Arinc updates the Asus RT-AC3100 and RT-AC88U DTs to have proper LED colors and function properties, NVMEM MAC addresses and removes duplicates and unnecessary properties and does a few Device Tree cleanups.. He then adds support for the Asus RT-AC3200 (BCM4709-based) and RT-AC3500 routers. - Jean-Michel adds DT nodes for the CSI Unicam camera interfaces on the Raspberry Pi 4 / BCM2711 SoCs - Florian adds support for the Ethernet LEDs on Raspberry Pi 4 B and Raspberry Pi 4 CM boards. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEm+Rq3+YGJdiR9yuFh9CWnEQHBwQFAmYwBsUACgkQh9CWnEQH BwTeNg//THwPFu55oCQ+CsI6xUAPmcffjEcMk1qiELOo7PyoY9UkjKtjOMCW44tZ uwAtzy3jMPaFI1Ng/EZPErz7KOlwoNeqIjTvOpbRw1tVJ/7tkrnk5vi8zqRQUv4a jrAv+yybXDaKD/aFX41KH43OfMl0Fi5CnxUqlb5U8Mm0awwBfz2jvnetaZAuueAd Hwet2Lt/jOX43GVVHRaxaqP/rJnr7xdUUW7iCQ+Qi2xvXJIpNj/mL6tvVAKFe2JZ sig3uh/NtK6Pp1xAX78aTuf0L4NLFqQpVORuO1ncb4wT92U0Yhi3r47z4reAM6GN nX5rLEjeV/yaRA2532c9MVALRT+4f1ic0Pq8Knj7WaH0bRrTjKQK4YiwR0KdXhy1 GGC58bUOa1HKynZXCDxVih0oOS4REd511WyiLqSPdpsvzrtHCqwC59LOh5PDaoEn 9aBof7eRK8r7KXEsvU3av5WiJjM+O2ILrRlfuiBt/nuvyvX1G3uSTq3Gncb4e2n8 1LWGpnj1CyW64seJ2v3a1Mx07ArWgy1wwg3iRt1aOMcKHrfO3evLdRwHlFq2Ke+t U0cvR6nlpo9H6CPCMCU/LmK3chYWBDlIghua3v7AJSL9p9o6RcWyAV8SrP/E60A4 0O1rfNdLhQkl5MmIyhA5QTaAvsGplb9QNkf8m9Rx7e8krDTJjXA= =400A -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmYwpCEACgkQYKtH/8kJ UiePmBAAlIjEJE9IE2DnrrqnCrSbGg08R5ZNWEHzSdPAXDVR3nUBrPXPosbCDKQE iBUyF8APNPFogzfQJXR86vw7Wx067R95M6TLpAI4CuT47YAx1ALvC3oEy5Xua6OE VgN+998sWLodnCAT8M/ZcmH5uWtCxWETwGNQJsU960sVa17h/q11WpM8NzKmSq3J h+toBPNBfdyGyd2UBqcdnCiX5nLLCWOdryBJYaOHiohCKlbMtqn7eYlEUdyCIq3O Q/O4p9gj92Df5rv2GTVycsO9LXbaYvIRsmcukxwR8FGV+mkIBmUaEfbazEbyjoJh kjRMfvQ08P3a44wTuUVJrrnEvP3X8JUteZucGR0A8zsndt57ZUznYBYYcT63DMbN /bDYbtbOOUu4/KkKt2eQiQAN1fApl22HhRybuuIlzN51mki3Qv9JioSVbQDbn6PU M1CcvGn83k/UzPFlINDWHogSO+MyrCNk8zYPWpKjxwWAM6Twx/Ly0cmui6+91SeM z4K0YZUYYH/1rCoScose2ByesAUu6HNBBGnYfobUSPCF5tMT7tMHd1kP5WxcStJ7 I58yLo+DFUX8EVePOfFx7QdzJR4JuVRKH498WnQ+0Xew6FpUhwvOC1DNK+W211jA gNpUQd9s4sV9nXT0gLSPr2rbJW2AS2O+Btphpg5NiYU3VSOJXSQ= =L8Aj -----END PGP SIGNATURE----- Merge tag 'arm-soc/for-6.10/devicetree' of https://github.com/Broadcom/stblinux into soc/dt This pull request contains Broadcom ARM-based SoCs Device Tree changes for 6.10, please pull the following: - Laurent converts the Raspberry Pi firmware DT binding to YAML, updates the firmware driver to use the proper 'struct device' reference for DMA mappings and drops unneeded properties from the DT node and finishes by removing the duplicate firmware-clocks property to bcm2835-rpi.dtsi.

Arm FF-A updates for v6.10
1. Support for handling notification pending interrupt(NPI)
The FF-A uses the notification pending interrupt to inform the receiver
that it has a pending notification. This is a virtual interrupt and is
used by the following type of receivers:
- A guest/VM running under a hypervisor(normal world usecase)
- An S-EL1 SP running under a S-EL2 SPMC(secure world only usecase)
Also, when the FF-A driver is running inside a guest VM under an
hypervisor, the driver/guest VM doesn't have the permission/capability
to request the creation of notification bitmaps. For a VM, the hypervisor
reserves memory for its VM and hypervisor framework notification bitmaps
and the SPMC reserves memory for its SP and SPMC framework notification
bitmaps before the hypervisor initializes it.
These changes include skipping of creation of notification bitmaps, some
refactoring around schedule receiver interrupt(SRI) handling and addition
of support for NPI.
2. Support for FF-A indirect messaging
The FFA_MSG_SEND2 can be used to transmit a partition message from
the Tx buffer of the sender(the driver in this case) endpoint to the Rx
buffer of the receiver endpoint and inform the scheduler that the
receiver endpoint must be run.
Apart from these two main features, there is an optimisation to avoid
queuing of a work when already running on the worker queue.

Arm SCMI updates for v6.10
1. Basic support for SCMI v3.2 pincontrol protocol
SCMI v3.2 introduces pincontrol protocol which is intended for
controlling pins and their configuration. The pin control protocol
provides commands to:
- List the pins, groups of pins, available functions, and their
association with each other.
- Set the parameter configuration and multiplexing of the pins or
groups of pins
- Optionally request exclusive access to a pin or group of pins.
- Optionally configure the permissions of an agent to access a pin
or group of pins.
These changes adds basic support for the same in the SCMI core layer
and an implementation of the generic scmi-pinctrl driver with associated
DT bindings.
2. Framework support for multiple vendors custom protocols
With the fixed space for vendor protocols, the possibility of having
multiple vendors implementing distinct SCMI vendor protocols with
the same overlapping protocol number is very high and with the need
to support them all in a single kernel image or a module is also high.
In order to implement the same we assume:
- vendor protocols has to be tagged at build time with a vendor_id
- vendor protocols could also optionally be tagged at build time with
sub_vendor_id and implementation version
At the initialisation all the built vendor protocols are registered
with the SCMI core using a key derived from the above tags
3. Logging and tracing improvements
This includes using dev_err_probe() to bail out from probe, adding
message dump traces for bad and unexpected replies and widening of
the tag buffer in trace_scmi_dump_msg to allow diverse tag names
4. Miscellaneous updates or improvements
This includes adding the accessor function get_max_msg_size() used
in pinctl protocol, updation of dt-bindings examples for protocol@13
to promote new bindings and simplification of scmi_devm_notifier_unregister

Merge tag 'scmi-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers
Arm SCMI updates for v6.10
1. Basic support for SCMI v3.2 pincontrol protocol
SCMI v3.2 introduces pincontrol protocol which is intended for
controlling pins and their configuration. The pin control protocol
provides commands to:
- List the pins, groups of pins, available functions, and their
association with each other.
- Set the parameter configuration and multiplexing of the pins or
groups of pins
- Optionally request exclusive access to a pin or group of pins.
- Optionally configure the permissions of an agent to access a pin
or group of pins.
These changes adds basic support for the same in the SCMI core layer
and an implementation of the generic scmi-pinctrl driver with associated
DT bindings.
2. Framework support for multiple vendors custom protocols
With the fixed space for vendor protocols, the possibility of having
multiple vendors implementing distinct SCMI vendor protocols with
the same overlapping protocol number is very high and with the need
to support them all in a single kernel image or a module is also high.
In order to implement the same we assume:
- vendor protocols has to be tagged at build time with a vendor_id
- vendor protocols could also optionally be tagged at build time with
sub_vendor_id and implementation version
At the initialisation all the built vendor protocols are registered
with the SCMI core using a key derived from the above tags
3. Logging and tracing improvements
This includes using dev_err_probe() to bail out from probe, adding
message dump traces for bad and unexpected replies and widening of
the tag buffer in trace_scmi_dump_msg to allow diverse tag names
4. Miscellaneous updates or improvements
This includes adding the accessor function get_max_msg_size() used
in pinctl protocol, updation of dt-bindings examples for protocol@13
to promote new bindings and simplification of scmi_devm_notifier_unregister

Qualcomm driver updates for v6.10
The Qualcomm SCM driver initialization order is improved, to avoid any potential for a client to find a half-initialized SCM instance. The handling of download mode bits is updated to not attempt QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is specified, and that path is changed to perform a read-modify-write to avoid updating unrelated bits. Error handling is corrected in the peripheral authentication service (PAS) functions, to release interconnect bandwidth votes in the case of an error. An unwanted error print on allocation error is also removed from this code path. The QSEECOM allow list is marked __maybe_unused to avoid build warnings when built with !OF. The error handling related to the interconnect API is cleaned up to avoid handling the impossible IS_ERR() condition. initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent drivers like regulators, interconnects and clocks are registered at this level. Another attempt is made to remove the strncpy() usage in cmd-db, this time with strtomem_pad() which has the correct characteristics. The bwmon regmap cache is changed to maple tree. After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers, the intention of not having them automatically load is documented. Operations on the pmic_glink client list is put under mutual exclusion, to avoid races when clients are being registered. pmic_glink client registered after the firmware notification arrived was not informed that the firmware was up, this is resolved. More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver. Checks for in-flight regulator requests in the RPMh RSC driver is improved to deal with the fact that these occupy multiple registers, so it's insufficient to just to direct address comparison. The socinfo drivers learns about X1 Elite and SMB2360 PMIC. The maintainers entry is split between the linux-arm-msm list and subset that is maintained in the qcom-soc tree, to avoid some confusion about maintainership. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmYtIvQVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FmLMQANqfDnrplxf3OpL3I8JEqeHYvdLF e12jXZyBlSCWRBEbphHZLKj8qSTFqpFgvqxIJ1fNqZ1AG9GeJTP8aGSkSnaYoym8 7uvSWRv2lZ13mQmaCM8PQMYJ7UhLitVfwKrLfSwV7GgqxqyJ5+tnTGpEdNE3VEhW VaiknaR7kV2T3mUmrrgivy+0rMLimDMOVu7TcLkw5aY4SaQuerElXz1/IZO29GLK QOqEbDsf8TcImZnMsnmMvbLO+AJ/NgmhpD9SDGTbzYtGEqsbVebklQDZNj9QXjWy o6zPoCsPn93x95jBwFp0HgdTye4UWZZ3cix/LkyyLja4l0hMJM2QOdDstmtgymbM itmWJ3rGfcK8Gjl6NEh+OSMq0rH84uJfXR0VrT/tRDkn4eTSk6DeZJD6lvpp1x43 2RwELsdlLobfS1znuq2hz+fkVBMh35USNadfC+B2xNyhihPKI1asG8UHu8mUz2MH /feyBxygaI3k9G3C6G4qNg3cjvY2MDqy+u6hOv9cG3CoS5z6aRxoGfxXS6I40ABz izoFaaae798Kau+VNAKw5OKC56UbRLlTSAVCmM5FItktK+5YIxbOIxRiMxgDxL8B JO6fUH5xUE0nF4Ni0OF233+qmfkO+0tRqiVUVEG4mNveyBgTiJtgrZOMAnqzoVmI BkagrDlbfbG2TvKb =E1Yk -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmYwAbIACgkQYKtH/8kJ Uicn4g//Te5hh/YrSw7z42Yu9Zj9N45JhxATZ5Vzsirr9s0YfdF40bbKnHQWeL+O qTf/3+egSwn5Dow0vQaEDhRTDJgaQFI9hie+ahR28vtrrgHUWjyXJx/L2yGR9kCX 1voErjOtCNomq0clDifo/Tr9v7l5Ky0+5OCeZx0TOHkcRjQo9p/ivTdYRhQzw7HN jfB23b3rqioUDOErsu+dpC9HFaPeP7iaM0IlPZyqjtW9Vir7Li7pZsmvhlLhFcwS xap0Zo77vKoojLTlVhKpJPCTq1qg1/s/WvPR4t1HnfxPcgaEFb0e9ZiFhmzQ5SzT tnA61jO/yIlvg3ScUdTlwC6TyI9h1dsNYLhhWyKyHdVn9mQDBAOgxd1+o8jFYx5L C2SznOzBxAQPhA81GNi5GJTRlVpixrwd5QsJ7MeQYM59J4+VbQeCjxgZLU0qzI4X OyKSx/i4zn7hRYxkuvCQns3fUQ8j8NZEF8HmkDmNeGKCD2UxdexmFFRQBQQzbhpL yQxyWoqrlf/iMimfnxjJ1xViTxfJdzdnif9Ah+vjWsplC5P1pty9lAutkLj++zOR cAJVV4IDSYhSlDiDo8jsOhfDCclVNw/gOFemUlG5Lf5VdZJ7F/lHTwouq6y7GTZ3 h3pF8xrGTnfM19zlznq/JTyafph/gTxTiTUH5ymBLm54xOzYd4E= =+dt0 -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.10 The Qualcomm SCM driver initialization order is improved, to avoid any potential for a client to find a half-initialized SCM instance.

firmware: smccc: Export revision soc_id function
The "SoC ID revision" as provided via the SMCCC SOCID interface can be valuable information for drivers, when certain functionality depends on a die revision, for instance.

firmware: arm_ffa: Add support for FFA_MSG_SEND2
The FFA_MSG_SEND2 can be used to transmit a partition message from the Tx buffer of the sender(the driver in this case) endpoint to the Rx buffer of the receiver endpoint. An invocation of the FFA_MSG_SEND2 transfers the ownership of the Tx buffer to the receiver endpoint(or any intermediate consumer). Completion of an FFA_MSG_SEND2 invocation transfers the ownership of the buffer back to the sender endpoint. The framework defines the FFA_MSG_SEND2 interface to transmit a partition message from the Tx buffer of the sender to the Rx buffer of a receiver and inform the scheduler that the receiver must be run.

firmware: arm_ffa: Fix kernel warning about incorrect SRI/NPI
If the firmware returns incorrect SRI/NRI number, we fail to set it up in the kernel which is absolutely fine. However, we don't reset the stashed value of sched_recv or notif_pend IRQs. When we call ffa_notifications_cleanup() in case of failures to setup the notifications, we end up calling free_percpu_irq() from ffa_uninit_pcpu_irq() which results in the following warning: | genirq: Flags mismatch irq 6. 00004401 (ARM-FFA-NPI) vs. 00004400 (IPI) | ARM FF-A: Error registering percpu NPI nIRQ 6 : -16 | ARM FF-A: Notification setup failed -16, not enabled | ------------[ cut here ]------------ | Trying to free already-free IRQ 6 | WARNING: CPU: 2 PID: 1 at kernel/irq/manage.c:2476 __free_percpu_irq+0x6c/0x138 | Modules linked in: | CPU: 2 PID: 1 Comm: swapper/0 Not tainted 6.9.0-rc3 #211 | Hardware name: FVP Base RevC (DT) | pstate: 614000c9 (nZCv daIF +PAN -UAO -TCO +DIT -SSBS BTYPE=--) | pc : __free_percpu_irq+0x6c/0x138 | lr : __free_percpu_irq+0x6c/0x138 | Call trace: | __free_percpu_irq+0x6c/0x138 | free_percpu_irq+0x48/0x84 | ffa_notifications_cleanup+0x78/0x164 | ffa_notifications_setup+0x368/0x3c0 | ffa_init+0x2b4/0x36c | do_one_initcall+0xe0/0x258 | do_initcall_level+0x8c/0xac | do_initcalls+0x54/0x94 | do_basic_setup+0x1c/0x28 | kernel_init_freeable+0x108/0x174 | kernel_init+0x20/0x1a4 | ret_from_fork+0x10/0x20 Fix the same by resetting the stashed copy of IRQ values to 0 in case of any failure to set them up properly.

Add a mechanism to be able to tag vendor protocol modules at compile-time with a vendor/sub_vendor string and an implementation version and then to choose to load, at run-time, only those vendor protocol modules matching as close as possible the vendor/subvendor identification advertised by the SCMI platform server. In this way, any in-tree existent vendor protocol module can be build and shipped by default in a single kernel image, even when using the same clashing protocol identification numbers, since the SCMI core will take care at run-time to load only the ones pertinent to the running system.

firmware: arm_ffa: Add support for handling notification pending interrupt(NPI)
The FF-A uses the notification pending interrupt to inform the receiver that it has a pending notification. This is a virtual interrupt and is used by the following type of receivers: 1. A guest/VM running under a hypervisor. 2. An S-EL1 SP running under a S-EL2 SPMC. The rules that govern the properties of the NPI are the same as the rules for the SRI with couple of exceptions. Both SRI and NPI can be supported simultaneously. The handling of NPI is also same as the handling of notification for the self/primary VM with ID 0 except the absence of global notification.

firmware: arm_ffa: Skip creation of the notification bitmaps
When the FF-A driver is running inside a guest VM under an hypervisor, the driver/guest VM doesn't have the permission/capability to request the creation of notification bitmaps. For a VM, the hypervisor reserves memory for its VM and hypervisor framework notification bitmaps and the SPMC reserves memory for its SP and SPMC framework notification bitmaps before the hypervisor initializes it. The hypervisor does not initialize a VM if memory cannot be reserved for all its notification bitmaps. So the creation of all the necessary bitmaps are already done when the driver initialises and hence it can be skipped. We rely on FFA_FEATURES(FFA_NOTIFICATION_BITMAP_CREATE) to fail when running in the guest to handle this in the driver.

efi: Clear up misconceptions about a maximum variable name size
The UEFI specification does not make any mention of a maximum variable name size, so the headers and implementation shouldn't claim that one exists either. Comments referring to this limit have been removed or rewritten, as this is an implementation detail local to the Linux kernel. Where appropriate, the magic value of 1024 has been replaced with EFI_VAR_NAME_LEN, as this is used for the efi_variable struct definition. This in itself does not change any behavior, but should serve as points of interest when making future changes in the same area. A related build-time check has been added to ensure that the special 512 byte sized buffer will not overflow with a potentially decreased EFI_VAR_NAME_LEN.

firmware: ti_sci: Unconditionally register reset handler
There was once a limitation that there could only be one system reset handler. Due to that we only would register this handler when a non-standard device tree property was found, else we left the default handler in place (usually PSCI). Now that we can have multiple handlers, and TI-SCI reset is always available in the firmware, register this handler unconditionally. This priority is left at the default so higher priority handlers (like PSCI) are still attempted first.

firmware: qcom: uefisecapp: Fix memory related IO errors and crashes
It turns out that while the QSEECOM APP_SEND command has specific fields
for request and response buffers, uefisecapp expects them both to be in
a single memory region. Failure to adhere to this has (so far) resulted
in either no response being written to the response buffer (causing an
EIO to be emitted down the line), the SCM call to fail with EINVAL
(i.e., directly from TZ/firmware), or the device to be hard-reset.
While this issue can be triggered deterministically, in the current form
it seems to happen rather sporadically (which is why it has gone
unnoticed during earlier testing). This is likely due to the two
kzalloc() calls (for request and response) being directly after each
other. Which means that those likely return consecutive regions most of
the time, especially when not much else is going on in the system.
Fix this by allocating a single memory region for both request and
response buffers, properly aligning both structs inside it. This
unfortunately also means that the qcom_scm_qseecom_app_send() interface
needs to be restructured, as it should no longer map the DMA regions
separately. Therefore, move the responsibility of DMA allocation (or
mapping) to the caller.

firmware: raspberrypi: Use correct device for DMA mappings
The buffer used to transfer data over the mailbox interface is mapped
using the client's device. This is incorrect, as the device performing
the DMA transfer is the mailbox itself. Fix it by using the mailbox
controller device instead.
This requires including the mailbox_controller.h header to dereference
the mbox_chan and mbox_controller structures. The header is not meant to
be included by clients. This could be fixed by extending the client API
with a function to access the controller's device.

firmware: coreboot: store owner from modules with coreboot_driver_register()
Modules registering driver with coreboot_driver_register() might
forget to set .owner field. The field is used by some of other kernel
parts for reference counting (try_module_get()), so it is expected that
drivers will set it.
Solve the problem by moving this task away from the drivers to the core
code, just like we did for platform_driver in

efi: pstore: Request at most 512 bytes for variable names
Work around a quirk in a few old (2011-ish) UEFI implementations, where
a call to `GetNextVariableName` with a buffer size larger than 512 bytes
will always return EFI_INVALID_PARAMETER.
This was already done to efivarfs in commit

x86/efistub: Don't clear BSS twice in mixed mode
Clearing BSS should only be done once, at the very beginning.
efi_pe_entry() is the entrypoint from the firmware, which may not clear
BSS and so it is done explicitly. However, efi_pe_entry() is also used
as an entrypoint by the mixed mode startup code, in which case BSS will
already have been cleared, and doing it again at this point will corrupt
global variables holding the firmware's GDT/IDT and segment selectors.
So make the memset() conditional on whether the EFI stub is running in
native mode.

x86/efistub: Clear decompressor BSS in native EFI entrypoint
The EFI stub on x86 no longer invokes the decompressor as a subsequent boot stage, but calls into the decompression code directly while running in the context of the EFI boot services. This means that when using the native EFI entrypoint (as opposed to the EFI handover protocol, which clears BSS explicitly), the firmware PE image loader is being relied upon to ensure that BSS is zeroed before the EFI stub is entered from the firmware. As Radek's report proves, this is a bad idea. Not all loaders do this correctly, which means some global variables that should be statically initialized to 0x0 may have junk in them. So clear BSS explicitly when entering via efi_pe_entry(). Note that zeroing BSS from C code is not generally safe, but in this case, the following assignment and dereference of a global pointer variable ensures that the memset() cannot be deferred or reordered.

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather
than uniformly. This is beneficial in heterogeneous memory environments
appearing with CXL.
- Christophe Leroy has contributed some cleanup and consolidation work
against the ARM pagetable dumping code in the series "mm: ptdump:
Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".
- Luis Chamberlain has added some additional xarray selftesting in the
series "test_xarray: advanced API multi-index tests".
- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.
- In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.
- In the series "selftests/mm: Output cleanups for the compaction test",
Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.
- Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic
improvements in worst-case mmap_lock hold times during certain
userfaultfd operations.
- Some page_owner enhancements and maintenance work from Oscar Salvador
in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"
- Uladzislau Rezki has contributed some vmalloc scalability improvements
in his series "Mitigate a vmap lock contention". It realizes a 12x
improvement for a certain microbenchmark.
- Some kexec/crash cleanup work from Baoquan He in the series "Split
crash out from kexec and clean up related config items".
- Some zsmalloc maintenance work from Chengming Zhou in the series
"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.
- Cleanups to our pagemap utility functions from Peter Xu in his series
"mm/treewide: Replace pXd_large() with pXd_leaf()".
- Nico Pache has fixed a few things with our hugepage selftests in his
series "selftests/mm: Improve Hugepage Test Handling in MM Selftests".
- Also, of course, many singleton patches to many things. Please see
the individual changelogs for details.

Merge tag 'pci-v6.9-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with
functions (Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when
CONFIG_SYSFS=y (Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around
an apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)
- Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
still don't advertise a legal size (Paul Menzel)
- Ignore expected DPC Surprise Down errors on hot removal (Smita
Koralahalli)
- Block runtime suspend while handling AER errors to avoid races that
prevent the device form being resumed from D3hot (Stanislaw
Gruszka)
Peer-to-peer DMA:
- Use atomic XA allocation in RCU read section (Christophe JAILLET)
ASPM:
- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E.
Box)
- Update save_save when ASPM config is changed, so a .slot_reset()
during error recovery restores the changed config, not the
.probe()-time config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)
- Return actual error code for pci_vntb_probe() failure (Yang
Yingliang)
Broadcom STB PCIe controller driver:
- Fix MDIO write polling, which previously never waited for
completion (Jonathan Bell)
Cadence PCIe endpoint driver:
- Clear the ARI "Next Function Number" of last function (Jasko-EXT
Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)
- Simplify by using clk_bulk*() API (Frank Li)
- Remove redundant DT clock and reg/reg-name details (Frank Li)
- Add i.MX95 DT and driver support for both Root Complex and Endpoint
mode (Frank Li)
Microsoft Hyper-V host bridge driver:
- Reduce memory usage by limiting ring buffer size to 16KB instead of
4 pages (Michael Kelley)
Qualcomm PCIe controller driver:
- Add X1E80100 DT and driver support (Abel Vesa)
- Add DT 'required-opps' for SoCs that require a minimum performance
level (Johan Hovold)
- Make DT 'msi-map-mask' optional, depending on how MSI interrupts
are mapped (Johan Hovold)
- Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
configuration isn't tuned correctly for L0s (Johan Hovold)
- Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and
separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
Kozlowski)
- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
Sarkar)
Synopsys DesignWare PCIe controller driver:
- Allocate 64-bit MSI address if no 32-bit address is available (Ajay
Agarwal)
- Fix endpoint Resizable BAR to actually advertise the required 1MB
size (Niklas Cassel)
MicroSemi Switchtec management driver:
- Release resources if the .probe() fails (Christophe JAILLET)
Miscellaneous:
- Make pcie_port_bus_type const (Ricardo B. Marliere)"

Pull power management updates from Rafael Wysocki:
"From the functional perspective, the most significant change here is
the addition of support for Energy Models that can be updated
dynamically at run time.
There is also the addition of LZ4 compression support for hibernation,
the new preferred core support in amd-pstate, new platforms support in
the Intel RAPL driver, new model-specific EPP handling in intel_pstate
and more.
Apart from that, the cpufreq default transition delay is reduced from
10 ms to 2 ms (along with some related adjustments), the system
suspend statistics code undergoes a significant rework and there is a
usual bunch of fixes and code cleanups all over.

ARM: SoC drivers for 6.9
This is the usual mix of updates for drivers that are used on (mostly
ARM) SoCs with no other top-level subsystem tree, including:
- The SCMI firmware subsystem gains support for version 3.2 of the
specification and updates to the notification code.
- Feature updates for Tegra and Qualcomm platforms for added
hardware support.
- A number of platforms get soc_device additions for identifying newly
added chips from Renesas, Qualcomm, Mediatek and Google.
- Trivial improvements for firmware and memory drivers amongst
others, in particular 'const' annotations throughout multiple
subsystems.

x86/efistub: Remap kernel text read-only before dropping NX attribute
Currently, the EFI stub invokes the EFI memory attributes protocol to strip any NX restrictions from the entire loaded kernel, resulting in all code and data being mapped read-write-execute. The point of the EFI memory attributes protocol is to remove the need for all memory allocations to be mapped with both write and execute permissions by default, and make it the OS loader's responsibility to transition data mappings to code mappings where appropriate. Even though the UEFI specification does not appear to leave room for denying memory attribute changes based on security policy, let's be cautious and avoid relying on the ability to create read-write-execute mappings. This is trivially achievable, given that the amount of kernel code executing via the firmware's 1:1 mapping is rather small and limited to the .head.text region. So let's drop the NX restrictions only on that subregion, but not before remapping it as read-only first. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |

efi/libstub: Add get_event_log() support for CC platforms
To allow event log info access after boot, EFI boot stub extracts the event log information and installs it in an EFI configuration table. Currently, EFI boot stub only supports installation of event log only for TPM 1.2 and TPM 2.0 protocols. Extend the same support for CC protocol. Since CC platform also uses TCG2 format, reuse TPM2 support code as much as possible.

efi/libstub: Measure into CC protocol if TCG2 protocol is absent
To accommodate confidential compute VMs that expose the simplified CC measurement protocol instead of the full-blown TCG2 one, fall back to the former if the latter does not exist. The CC protocol was designed to be used in this manner, which is why the types and prototypes have been kept the same where possible. So reuse the existing code, and only deviate from the TCG2 code path where needed.

If the virtual firmware implements TPM support, TCG2 protocol will be used for kernel measurements and event logging support. But in CC environment, not all platforms support or enable the TPM feature. UEFI specification [1] exposes protocol and interfaces used for kernel measurements in CC platforms without TPM support. More details about the EFI CC measurements and logging can be found in [1].

efi/tpm: Use symbolic GUID name from spec for final events table
The LINUX_EFI_ GUID identifiers are only intended to be used to refer to GUIDs that are part of the Linux implementation, and are not considered external ABI. (Famous last words). GUIDs that already have a symbolic name in the spec should use that name, to avoid confusion between firmware components. So use the official name EFI_TCG2_FINAL_EVENTS_TABLE_GUID for the TCG2 'final events' configuration table.

efi/libstub: Use TPM event typedefs from the TCG PC Client spec
Our efi_tcg2_tagged_event is not defined in the EFI spec, but it is not a local invention either: it was taken from the TCG PC Client spec, where it is called TCG_PCClientTaggedEvent. Note that this spec also contains some guidance on how to populate it, which is not being followed closely at the moment; it claims that the event size should cover the TCG_PCClientTaggedEvent and its payload only, but it currently covers the preceding efi_tcg2_event too. However, this directly contradicts the TCG EFI protocol specification, which states very clearly that the event size should cover the entire data structure, including the leading efi_tcg2_event_t struct. So rename the struct and document its provenance, but retain the existing logic to populate the size field.

PCI/AER: Generalize TLP Header Log reading
Both AER and DPC RP PIO provide TLP Header Log registers (PCIe r6.1 secs 7.8.4 & 7.9.14) to convey error diagnostics but the struct is named after AER as the struct aer_header_log_regs. Also, not all places that handle TLP Header Log use the struct and the struct members are named individually. Generalize the struct name and members, and use it consistently where TLP Header Log is being handled so that a pcie_read_tlp_log() helper can be easily added.

x86/boot: Move mem_encrypt= parsing to the decompressor
The early SME/SEV code parses the command line very early, in order to decide whether or not memory encryption should be enabled, which needs to occur even before the initial page tables are created. This is problematic for a number of reasons: - this early code runs from the 1:1 mapping provided by the decompressor or firmware, which uses a different translation than the one assumed by the linker, and so the code needs to be built in a special way; - parsing external input while the entire kernel image is still mapped writable is a bad idea in general, and really does not belong in security minded code; - the current code ignores the built-in command line entirely (although this appears to be the case for the entire decompressor) Given that the decompressor/EFI stub is an intrinsic part of the x86 bootable kernel image, move the command line parsing there and out of the core kernel. This removes the need to build lib/cmdline.o in a special way, or to use RIP-relative LEA instructions in inline asm blocks. This involves a new xloadflag in the setup header to indicate that mem_encrypt=on appeared on the kernel command line.

to enhance notification handling and other miscellaneous updates.
1. Enhancements to notification handling
Until now, trying to register a notifier for an unsuppported
notification returned an error genrating unneeded message exchanges
with the SCMI platform. This can be avoided by looking up in advance
the specific protocol and resources available.
With these changes SCMI driver user will fail to register a notifier
if the related command or resource is not supported (like before)
without the need of exchanging any message.
Perf notifications are also extended to provide the pre-calculated
frequencies corresponding to the level or index carried by the
2. More SCMI v3.2 related updates
One of the main addition includes a centralized support to the SCMI
core to handle v3.2 optional protocol version negotiation, so that
at protocol initialization time, if the platform advertised version
is newer than supported by the kernel and protocol version negotiation
is supported, the SCMI core will attempt to negotiate an older protocol
version.
It also includes the clock get permissions which indicates if any of
the clock operations are forbidden by the platform for the OSPM agent.
It can be used in the clock driver to avoid unnecessary message
exchanges between the kernel and the platform which will always end
up with the failure. It also includes other missing bits of clock
v3.2 protocol so that the supported protocol version can be bumped
to 0x30000 (v3.2).
3. Miscellaneous updates
This includes addition of warning if the domain frequency multiplier
is 0 or rounded off to indicate the actual frequencies are either
wrong ot rounded off, hardening of clock domain info lookups, addition
of multiple protocols registration support within a SCMI driver,
update to SCMI entry in MAINTAINERS to include HWMON driver and
constifying the scmi_bus_type structure.
This also includes couple for fixes to minor issues: double free in
SMC transport cleanup path and struct kernel-doc warnings in optee
transport.

crash: split vmcoreinfo exporting code out from crash_core.c
Now move the relevant codes into separate files:
kernel/crash_reserve.c, include/linux/crash_reserve.h.
And add config item CRASH_RESERVE to control its enabling.
And also update the old ifdeffery of CONFIG_CRASH_CORE, including of
<linux/crash_core.h> and config item dependency on CRASH_CORE
accordingly.
And also do renaming as follows:
- arch/xxx/kernel/{crash_core.c => vmcore_info.c}
because they are only related to vmcoreinfo exporting on x86, arm64,
riscv.
And also Remove config item CRASH_CORE, and rely on CONFIG_KEXEC_CORE to
decide if build in crash_core.c.
[yang.lee@linux.alibaba.com: remove duplicated include in vmcore_info.c]
