77f5032e94 firmware: arm_scmi: Fix possible frequency truncation when using level indexing mode
The multiplier is already promoted to unsigned long, however the
frequency calculations done when using level indexing mode doesn't
use the multiplier computed. It instead hardcodes the multiplier
value of 1000 at all the usage sites.

Clean that up by assigning the multiplier value of 1000 when using
the perf level indexing mode and update the frequency calculations to
use the multiplier instead. It should fix the possible frequency
truncation for all the values greater than or equal to 4GHz on 64-bit
machines.

8e3c98d918 firmware: arm_scmi: Fix frequency truncation by promoting multiplier type
Fix the possible frequency truncation for all values equal to or greater
4GHz on 64bit machines by updating the multiplier 'mult_factor' to
'unsigned long' type. It is also possible that the multiplier itself can
be greater than or equal to 2^32. So we need to also fix the equation
computing the value of the multiplier.

riscv: Optimize bitops with Zbb extension
This patch leverages the alternative mechanism to dynamically optimize
bitops (including __ffs, __fls, ffs, fls) with Zbb instructions. When
Zbb ext is not supported by the runtime CPU, legacy implementation is
used. If Zbb is supported, then the optimized variants will be selected
via alternative patching.

The legacy bitops support is taken from the generic C implementation as
fallback.

If the parameter is a build-time constant, we leverage compiler builtin to
calculate the result directly, this approach is inspired by x86 bitops
implementation.

EFI stub runs before the kernel, so alternative mechanism should not be
used there, this patch introduces a macro NO_ALTERNATIVE for this purpose.

   - Andrey Konovalov has sent along the series 'kasan: assorted fixes
     and improvements' which does those things

   - Some page allocator maintenance work from Kemeng Shi in the series
     'Two minor cleanups to break_down_buddy_pages'

   - In thes series 'New selftest for mm' Breno Leitao has developed
     another MM self test which tickles a race we had between madvise()
     and page faults

   - In the series 'Add folio_end_read' Matthew Wilcox provides cleanups
     and an optimization to the core pagecache code

   - Nhat Pham has added memcg accounting for hugetlb memory in the
     series 'hugetlb memcg accounting'

   - Cleanups and rationalizations to the pagemap code from Lorenzo
     Stoakes, in the series 'Abstract vma_merge() and split_vma()'

   - Audra Mitchell has fixed issues in the procfs page_owner code's new
     timestamping feature which was causing some misbehaviours. In the
     series 'Fix page_owner's use of free timestamps'

   - Lorenzo Stoakes has fixed the handling of new mappings of sealed
     files in the series 'permit write-sealed memfd read-only shared
     mappings'

   - Mike Kravetz has optimized the hugetlb vmemmap optimization in the
     series 'Batch hugetlb vmemmap modification operations'

   - Some buffer_head folio conversions and cleanups from Matthew Wilcox
     in the series 'Finish the create_empty_buffers() transition'

   - As a page allocator performance optimization Huang Ying has added
     automatic tuning to the allocator's per-cpu-pages feature, in the
     series 'mm: PCP high auto-tuning'

   - Roman Gushchin has contributed the patchset 'mm: improve
     performance of accounted kernel memory allocations' which improves
     their performance by ~30% as measured by a micro-benchmark

   - folio conversions from Kefeng Wang in the series 'mm: convert page
     cpupid functions to folios'

   - Some kmemleak fixups in Liu Shixin's series 'Some bugfix about
     kmemleak'

   - Qi Zheng has improved our handling of memoryless nodes by keeping
     them off the allocation fallback list. This is done in the series
     'handle memoryless nodes more appropriately'

   - khugepaged conversions from Vishal Moola in the series 'Some
     khugepaged folio conversions'"

[ bcachefs conflicts with the dynamically allocated shrinkers have been
  resolved as per Stephen Rothwell in

     https://lore.kernel.org/all/20230913093553.4290421e@canb.auug.org.au/

  with help from Qi Zheng.

1e0c505e13 asm-generic updates for v6.7
The ia64 architecture gets its well-earned retirement as planned,
 now that there is one last (mostly) working release that will
 be maintained as an LTS kernel.
 
 The architecture specific system call tables are updated for
 the added map_shadow_stack() syscall and to remove references
 to the long-gone sys_lookup_dcookie() syscall.

385903a7ec SoC driver updates for 6.7
The highlights for the driver support this time are
 
  - Qualcomm platforms gain support for the Qualcomm Secure Execution
    Environment firmware interface to access EFI variables on certain
    devices, and new features for multiple platform and firmware drivers.
 
  - Arm FF-A firmware support gains support for v1.1 specification features,
    in particular notification and memory transaction descriptor changes.
 
  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
    In particular, this contains portions of the treewide conversion to
    use __counted_by annotations and the device_get_match_data helper.

79614953e8 firmware: xilinx: Move EXPORT_SYMBOL_GPL next to zynqmp_pm_feature definition
As mentioned in Documentation/process/coding-style.rst:
In source files, separate functions with one blank line. If the function
is exported, the **EXPORT** macro for it should follow immediately after
the closing function brace line.

So inline with guideline move zynqmp_pm_feature export symbol after its
definition.

3a568e3a96 ARM: SoC fixes for 6.7, part 3
A couple of platforms have some last-minute fixes for 6.7, in particular
 
  - riscv gets some fixes for noncoherent DMA on the renesas and thead
    platforms and dts fix for SPI on the visionfive 2 board
 
  - Qualcomm Snapdragon gets three dts fixes to address board specific
    regressions on the pmic and gpio nodes
 
  - Rockchip platforms get multiple dts fixes to address issues on
    the recent rk3399 platform as well as the older rk3128 platform
    that apparently regressed a while ago.
 
  - TI OMAP gets some trivial code and dts fixes and a regression fix
    for the omap1 ams-delta modem
 
  - NXP i.MX firmware has one fix for a use-after-free but in its
    error handling.

50e782a86c efi/unaccepted: Fix soft lockups caused by parallel memory acceptance
Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.

The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.

To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.

A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.

Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.

Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.

The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

This introduces partial support for the Qualcomm Secure Execution
 Environment SCM interface, and uses this to implement EFI variable
 access on the Windows On Snapdragon devices (for now).
 
 The 32/64-bit calling convention detector of the SCM interface is
 updated to not choose 64-bit convention when Linux is 32-bit. The
 "extern" specifier is dropped from the interface include file.
 
 The LLCC driver gains support for carrying configuration for multiple
 different system/DDR configurations for a given platform, and selecting
 between them. Support for Q[DR]U1000 is added to the driver.
 
 All exported symbols are transitioned to EXPORT_SYMBOL_GPL().
 
 The platform_drivers in the Qualcomm SoC are transitioned to the
 void-returning remove_new implementation.
 
 The rmtfs memory driver gains support for leaving guard pages around the
 used area, to avoid issues if the allocation happens to be placed
 adjacent to another protected memory region.
 
 The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and
 various PMICs used together with SM8550.

b8466fe82b efi: move screen_info into efi init code
After the vga console no longer relies on global screen_info, there are
only two remaining use cases:

 - on the x86 architecture, it is used for multiple boot methods
   (bzImage, EFI, Xen, kexec) to commucate the initial VGA or framebuffer
   settings to a number of device drivers.

 - on other architectures, it is only used as part of the EFI stub,
   and only for the three sysfb framebuffers (simpledrm, simplefb, efifb).

Remove the duplicate data structure definitions by moving it into the
efi-init.c file that sets it up initially for the EFI case, leaving x86
as an exception that retains its own definition for non-EFI boots.

The added #ifdefs here are optional, I added them to further limit the
reach of screen_info to configurations that have at least one of the
users enabled.

555624c0d1 vgacon: clean up global screen_info instances
To prepare for completely separating the VGA console screen_info from
the one used in EFI/sysfb, rename the vgacon instances and make them
local as much as possible.

ia64 and arm both have confurations with vgacon and efi, but the contents
never overlaps because ia64 has no EFI framebuffer, and arm only has
vga console on legacy platforms without EFI. Renaming these is required
before the EFI screen_info can be moved into drivers/firmware.

The ia64 vga console is actually registered in two places from
setup_arch(), but one of them is wrong, so drop the one in pcdp.c and
fix the one in setup.c to use the correct conditional.

x86 has to keep them together, as the boot protocol is used to switch
between VGA text console and framebuffer through the screen_info data.

d3cd3b5501 Arm FF-A updates for v6.7
The main addition is the initial support for the notifications and
 memory transaction descriptor changes added in FF-A v1.1 specification.
 
 The notification mechanism enables a requester/sender endpoint to notify
 a service provider/receiver endpoint about an event with non-blocking
 semantics. A notification is akin to the doorbell between two endpoints
 in a communication protocol that is based upon the doorbell/mailbox
 mechanism.
 
 The framework is responsible for the delivery of the notification from
 the ender to the receiver without blocking the sender. The receiver
 endpoint relies on the OS scheduler for allocation of CPU cycles to
 handle a notification.
 
 OS is referred as the receiver’s scheduler in the context of notifications.
 The framework is responsible for informing the receiver’s scheduler that
 the receiver must be run since it has a pending notification.
 
 The series also includes support for the new format of memory transaction
 descriptors introduced in v1.1 specification.
 
 Apart from the main additions, it includes minor fixes to re-enable FF-A
 drivers usage of 32bit mode of messaging and kernel warning due to the
 missing assignment of IDR allocation ID to the FFA device. It also adds
 emitting 'modalias' to the base attribute of FF-A devices.

Arm FF-A updates for v6.7

The main addition is the initial support for the notifications and
memory transaction descriptor changes added in FF-A v1.1 specification.

The notification mechanism enables a requester/sender endpoint to notify
a service provider/receiver endpoint about an event with non-blocking
semantics. A notification is akin to the doorbell between two endpoints
in a communication protocol that is based upon the doorbell/mailbox
mechanism.

The framework is responsible for the delivery of the notification from
the ender to the receiver without blocking the sender. The receiver
endpoint relies on the OS scheduler for allocation of CPU cycles to
handle a notification.

OS is referred as the receiver’s scheduler in the context of notifications.
The framework is responsible for informing the receiver’s scheduler that
the receiver must be run since it has a pending notification.

The series also includes support for the new format of memory transaction
descriptors introduced in v1.1 specification.

Apart from the main additions, it includes minor fixes to re-enable FF-A
drivers usage of 32bit mode of messaging and kernel warning due to the
missing assignment of IDR allocation ID to the FFA device. It also adds
emitting 'modalias' to the base attribute of FF-A devices.

d1debb7b32 Arm SCMI updates for v6.7
Main additions this time include:
 
 1. SCMI v3.2 clock configuration support:
    This helps to retrieve the enabled state of a clock as well as allow
    to set OEM specific clock configurations.
 
 2. Support for generic performance scaling(DVFS):
    The current SCMI DVFS support is limited to the CPUs in the kernel.
    This extension enables it to used for all kind of devices and not
    only for the CPUs. It updates the SCMI cpufreq to utilize the power
    domain bindings. It also adds a more generic SCMI performance domain
    based on the genpd framework that as be used for all the non-CPU
    devices.
 
 3. Extend the generic performance scaling(DVFS) support for firmware
    driver OPPs:
    Consumer drivers for devices that are attached to the SCMI performance
    domain can't make use of the current OPP library to scale performance
    as the OPPs are firmware driven and often obtained from the firmware
    rather than the device tree. These changes extend the generic OPP
    and genpd PM domain frameworks to identify and utilise these firmware
    driven OPPs.
 
 4. SCMI v3.2 clock parent support:
    This enables the support for discovering and changing parent clocks
    and extending the SCMI clk driver to use the same.
 
 5. Qualcom SMC/HVC transport support:
    The Qualcomm virtual platforms require capability id in the hypervisor
    call to identify which doorbell to assert when supporting multiple
    SMC/HVC based SCMI transport channels. Extra parameter is added to
    support the same and the same is obtained at the fixed address in the
    shared memory which is initialised by the firmware.
 
 6. Move the existing SCMI power domain driver under drivers/pmdomain
 
 Apart from the above main changes, it also include couple of minor fixes
 and cosmetic reworks.

ea608a01d4 firmware: tegra: Add suspend hook and reset BPMP IPC early on resume
Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp'
to mark if BPMP is suspended. Also, add a 'flags' field in the
'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be
set from the Tegra MC driver to signal that the reset of BPMP IPC
channels is required before sending MRQ to the BPMP FW. Together both
the fields allow us to handle any requests that might be sent too soon
as they can cause hang during system resume.

One case where we see BPMP requests being sent before the BPMP driver
has resumed is the memory bandwidth requests which are triggered by
onlining the CPUs during system resume. The CPUs are onlined before the
BPMP has resumed and we need to reset the BPMP IPC channels to handle
these requests.

The additional check for 'flags' is done to avoid any un-intended BPMP
IPC reset if the tegra_bpmp_transfer*() API gets called during suspend
sequence after the BPMP driver is suspended.

operation. This patch addresses the problem by releasing the old memory
before setting the pointer to NULL in case of a krealloc failure. This

This causes the firmware to throw an exception because the Console IO

per UEFI 2.9, section 12.1:

 "This protocol is used to handle input and output of text-based

So drop the diagnostic warning from this function. We might add back a

This change adds the support for SCMI message exchange on Qualcomm
virtual platforms.

The hypervisor associates an object-id also known as capability-id
with each smc/hvc doorbell object. The capability-id is used to
identify the doorbell from the VM's capability namespace, similar
to a file-descriptor.

The hypervisor, in addition to the function-id, expects the capability-id
to be passed in x1 register when SMC/HVC call is invoked.

The capability-id is allocated by the hypervisor on bootup and is stored in
the shmem region by the firmware before starting Linux.

113580530e firmware: arm_ffa: Update memory descriptor to support v1.1 format
Update memory transaction descriptor structure to accommodate couple of
new entries in v1.1 which were previously marked reserved and MBZ(must
be zero).

It also removes the flexible array member ep_mem_access in the memory
transaction descriptor structure as it need not be at fixed offset.
Also update ffa_mem_desc_offset() accessor to handle both old and new
formats of memory transaction descriptors.

The updated ffa_mem_region structure aligns with new format in v1.1 and
hence the driver/user must take care not to use members beyond and
including ep_mem_offset when using the old format.

e4607b84c6 firmware: arm_ffa: Switch to using ffa_mem_desc_offset() accessor
In preparation to add support to the new memory transaction descriptor,
the ep_mem_access member needs to be removed and hence even the macro
COMPOSITE_OFFSET(). Let us switch to using the new ffa_mem_desc_offset()
accessor in ffa_setup_and_transmit().

This will enable adding the support for new format transparently without
any changes here again.

77bbfe607b firmware: arm_scmi: Add support for clock parents
SCMI v3.2 spec introduces CLOCK_POSSIBLE_PARENTS_GET, CLOCK_PARENT_SET
and CLOCK_PARENT_GET. Add support for these to enable clock parents
and use them in the clock driver.

908af696c5 firmware: arm_scpi: Use device_get_match_data()
Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

c9b21ef0d0 firmware: arm_ffa: Simplify the computation of transmit and fragment length
The computation of endpoint memory access descriptor's composite memory
region descriptor offset is using COMPOSITE_CONSTITUENTS_OFFSET which is
unnecessary complicated. Composite memory region descriptor always follow
the endpoint memory access descriptor array and hence it is computed
accordingly. COMPOSITE_CONSTITUENTS_OFFSET is useless and wrong for any
input other than endpoint memory access descriptor count.

Let us drop the usage of COMPOSITE_CONSTITUENTS_OFFSET to simplify the
computation of total transmit and fragment length in the memory
transactions.

1b6bf41b7a firmware: arm_ffa: Add notification handling mechanism
With all the necessary plumbing in place, let us add handling the
notifications as part of schedule receiver interrupt handler. In order
to do so, we need to just register scheduling callback on behalf of the
driver partition.
