Objtool changes for v6.1:
- Remove the "ANNOTATE_NOENDBR on ENDBR" warning: it's not
really useful and only found a non-bug false positive so far.
- Properly decode LOOP/LOOPE/LOOPNE, which were missing from
the x86 decoder. Because these instructions are rather
ineffective, they never showed up in compiler output,
but they are simple enough to support, so add them for
completeness.
- A bit more cross-arch preparatory work.

Locking changes for v6.1:
- Disable preemption in rwsem_write_trylock()'s attempt to
take the rwsem, to avoid RT tasks hogging the CPU, which
managed to preempt this function after the owner has
been cleared but before a new owner is set. Also add
debug checks to enforce this.
- Add __lockfunc to more slow path functions and add
__sched to semaphore functions.
- Mark spinlock APIs noinline when the respective CONFIG_INLINE_SPIN_*
toggles are disabled, to reduce LTO text size.
- Print more debug information when lockdep gets confused
in look_up_lock_class().
- Improve header file abuse checks.
- Misc cleanups

ucounts: Split rlimit and ucount values and max values
After the ucount rlimit code was merged a bunch of small but
siginificant bugs were found and fixed. At the time it was realized
that part of the problem was that while the ucount rlimits were very
similar to the oridinary ucounts (in being nested counts with limits)
the semantics were slightly different and the code would be less error
prone if there was less sharing. This is the long awaited cleanup
that should hopefully keep things more comprehensible and less error
prone for whoever needs to touch that code next.

ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT
Recently I had a conversation where it was pointed out to me that
SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
difficult for a tracer to handle.
Keeping SIGKILL working after the process has been killed is pain
from an implementation point of view.
So since the debuggers don't want this behavior let's see if we can
remove this wart for the userspace API
If a regression is detected it should only need to be the last change
that is the reverted. The other two are just general cleanups that
make the last patch simpler.

signal: Ensure SIGNAL_GROUP_EXIT gets set in do_group_exit
signal: Guarantee that SIGNAL_GROUP_EXIT is set on process exit
signal: Drop signals received after a fatal signal has been processed

The first batch of KVM patches, mostly covering x86, which I
am sending out early due to me travelling next week. There is a lone mm patch for which Andrew gave an informal ack at https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org. I will send the bulk of ARM work, as well as other architectures, at the end of next week. ARM: * Account stage2 page table allocations in memory stats. x86: * Account EPT/NPT arm64 page table allocations in memory stats. * Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses. * Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of Hyper-V now support eVMCS fields associated with features that are enumerated to the guest. * Use KVM's sanitized VMCS config as the basis for the values of nested VMX capabilities MSRs. * A myriad event/exception fixes and cleanups. Most notably, pending exceptions morph into VM-Exits earlier, as soon as the exception is queued, instead of waiting until the next vmentry. This fixed a longstanding issue where the exceptions would incorrecly become double-faults instead of triggering a vmexit; the common case of page-fault vmexits had a special workaround, but now it's fixed for good. * A handful of fixes for memory leaks in error paths. * Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow. * Never write to memory from non-sleepable kvm_vcpu_check_block() * Selftests refinements and cleanups. * Misc typo cleanups. Generic: * remove KVM_REQ_UNHALT -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmM2zwcUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroNpbwf+MlVeOlzE5SBdrJ0TEnLmKUel1lSz QnZzP5+D65oD0zhCilUZHcg6G4mzZ5SdVVOvrGJvA0eXh25ruLNMF6jbaABkMLk/ FfI1ybN7A82hwJn/aXMI/sUurWv4Jteaad20JC2DytBCnsW8jUqc49gtXHS2QWy4 3uMsFdpdTAg4zdJKgEUfXBmQviweVpjjl3ziRyZZ7yaeo1oP7XZ8LaE1nR2l5m0J mfjzneNm5QAnueypOh5KhSwIvqf6WHIVm/rIHDJ1HIFbgfOU0dT27nhb1tmPwAcE +cJnnMUHjZqtCXteHkAxMClyRq0zsEoKk0OGvSOOMoq3Q0DavSXUNANOig== =/hqX -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "The first batch of KVM patches, mostly covering x86.

Merge tag 'efi-next-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
"A bit more going on than usual in the EFI subsystem. The main driver
for this has been the introduction of the LoonArch architecture last
cycle, which inspired some cleanup and refactoring of the EFI code.
Another driver for EFI changes this cycle and in the future is
confidential compute.
The LoongArch architecture does not use either struct bootparams or DT
natively [yet], and so passing information between the EFI stub and
the core kernel using either of those is undesirable. And in general,
overloading DT has been a source of issues on arm64, so using DT for
this on new architectures is a to avoid for the time being (even if we
might converge on something DT based for non-x86 architectures in the
future). For this reason, in addition to the patch that enables EFI
boot for LoongArch, there are a number of refactoring patches applied
on top of which separate the DT bits from the generic EFI stub bits.
These changes are on a separate topich branch that has been shared
with the LoongArch maintainers, who will include it in their pull
request as well. This is not ideal, but the best way to manage the
conflicts without stalling LoongArch for another cycle.
Another development inspired by LoongArch is the newly added support
for EFI based decompressors. Instead of adding yet another
arch-specific incarnation of this pattern for LoongArch, we are
introducing an EFI app based on the existing EFI libstub
infrastructure that encapulates the decompression code we use on other
architectures, but in a way that is fully generic. This has been
developed and tested in collaboration with distro and systemd folks,
who are eager to start using this for systemd-boot and also for arm64
secure boot on Fedora. Note that the EFI zimage files this introduces
can also be decompressed by non-EFI bootloaders if needed, as the
image header describes the location of the payload inside the image,
and the type of compression that was used. (Note that Fedora's arm64
GRUB is buggy [0] so you'll need a recent version or switch to
systemd-boot in order to use this.)
Finally, we are adding TPM measurement of the kernel command line
provided by EFI. There is an oversight in the TCG spec which results
in a blind spot for command line arguments passed to loaded images,
which means that either the loader or the stub needs to take the
measurement. Given the combinatorial explosion I am anticipating when
it comes to firmware/bootloader stacks and firmware based attestation
protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now
when it comes to EFI measured boot, which is that the kernel measures
the initrd and command line. Intermediate loaders can measure
additional assets if needed, but with the baseline in place, we can
deploy measured boot in a meaningful way even if you boot into Linux
straight from the EFI firmware.
Summary:
- implement EFI boot support for LoongArch
- implement generic EFI compressed boot support for arm64, RISC-V and
LoongArch, none of which implement a decompressor today
- measure the kernel command line into the TPM if measured boot is in
effect
- refactor the EFI stub code in order to isolate DT dependencies for
architectures other than x86
- avoid calling SetVirtualAddressMap() on arm64 if the configured
size of the VA space guarantees that doing so is unnecessary
- move some ARM specific code out of the generic EFI source files
- unmap kernel code from the x86 mixed mode 1:1 page tables"

Here's the main clk pull request for this merge window. We have some
late breaking reports that a patch series to rework clk rate range
support broke boot on some devices, so I've left that branch out of this
PR. Hopefully we can get to that next week, or punt on it and let it
bake another cycle. That means we don't really have any changes to the
core framework this time around besides a few typo fixes. Instead this
is all clk driver updates and fixes.
The usual suspects are here (again), with Qualcomm dominating the
diffstat. We look to have gained support for quite a few new Qualcomm
SoCs and Dmitry worked on updating many of the existing Qualcomm drivers
to use clk_parent_data. After that we have MediaTek drivers getting some
much needed updates, in particular to support GPU DVFS. There are also
quite a few Samsung clk driver patches, but that's mostly because there
was a maintainer change and so last release we missed some of those
patches.
Overall things look normal, but I'm slowly reviewing core framework code
nowadays and that shows given the rate range patches had to be yanked
last minute. Let's hope this situation changes soon.

Merge tag 'gpio-updates-for-v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have a single new driver, support for a bunch of new models,
improvements in drivers and core gpiolib code as well device-tree
bindings changes.
Summary:
New driver:
- IMX System Controller Unit GPIOs
GPIO core:
- add fdinfo output for the GPIO character device file descriptors
(allows user-space to determine which processes own which GPIO
lines)
- improvements to OF GPIO code
- new quirk for Asus UM325UAZ in gpiolib-acpi
- new quirk for Freescale SPI in gpiolib-of
Driver improvements:
- add a new macro that reduces the amount of boilerplate code in ISA
drivers and use it in relevant drivers
- support two new models in gpio-pca953x
- support new model in gpio-f7188x
- convert more drivers to use immutable irq chips
- other minor tweaks
Device-tree bindings:
- add DT bindings for gpio-imx-scu
- convert Xilinx GPIO bindings to YAML
- reference the properties from the SPI peripheral device-tree
bindings instead of providing custom ones in the GPIO controller
document
- add parsing of GPIO hog nodes to the DT bindings for gpio-mpfs-gpio
- relax the node name requirements in gpio-stmpe
- add new models for gpio-rcar and gpio-pxa95xx
- add a new vendor prefix: Diodes (for Diodes, Inc.)
Misc:
- pulled in the immutable branch from the x86 platform drivers tree
including support for a new simatic board that depends on GPIO
changes"

Staging driver changes for 6.1-rc1
Here is the large set of staging driver changes for 6.1-rc1.
Nothing really interesting in here at all except we deleted a driver
(fwserial) as no one had been using it for a long time. Other than
that, just the normal cleanups and minor fixes:
- rtl8723bs driver cleanups
- loads of r8188eu driver cleanups, making the driver smaller and
fixing up some firmware dependency issues.
- vt6655 driver cleanups.
- lots of other small staging driver cleanups.
All of these have been in linux-next for a while with no reported
issues.

NO_IRQ is used to check the return of irq_of_parse_and_map(). On some architecture NO_IRQ is 0, on other architectures it is -1. irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.

The struct sdesc is just a wrapper around shash_desc, with exact same

passed to the crypto API anyway.
Also remove the crypto_shash pointers as they can be accessed via
shash_desc->tfm (and are actually only used in the setkey calls).

When we probe about 200 virtio_blk devices,it will fail and the stack is printed as follows: [25338.485128] virtio-pci 0000:b3:00.0: virtio_pci: leaving for legacy driver [25338.496174] genirq: Flags mismatch irq 0. 00000080 (virtio418) vs. 00015a00 (timer) [25338.503822] CPU: 20 PID: 5431 Comm: kworker/20:0 Kdump: loaded Tainted: G OE --------- - - 4.18.0-305.30.1.el8.x86_64 [25338.516403] Hardware name: Inspur NF5280M5/YZMB-00882-10E, BIOS 4.1.21 08/25/2021 [25338.523881] Workqueue: events work_for_cpu_fn [25338.528235] Call Trace: [25338.530687] dump_stack+0x5c/0x80 [25338.534000] __setup_irq.cold.53+0x7c/0xd3 [25338.538098] request_threaded_irq+0xf5/0x160 [25338.542371] vp_find_vqs+0xc7/0x190 [25338.545866] init_vq+0x17c/0x2e0 [virtio_blk] [25338.550223] ? ncpus_cmp_func+0x10/0x10 [25338.554061] virtblk_probe+0xe6/0x8a0 [virtio_blk] [25338.558846] virtio_dev_probe+0x158/0x1f0 [25338.562861] really_probe+0x255/0x4a0 [25338.566524] ? __driver_attach_async_helper+0x90/0x90 [25338.571567] driver_probe_device+0x49/0xc0 [25338.575660] bus_for_each_drv+0x79/0xc0 [25338.579499] __device_attach+0xdc/0x160 [25338.583337] bus_probe_device+0x9d/0xb0 [25338.587167] device_add+0x418/0x780 [25338.590654] register_virtio_device+0x9e/0xe0 [25338.595011] virtio_pci_probe+0xb3/0x140 [25338.598941] local_pci_probe+0x41/0x90 [25338.602689] work_for_cpu_fn+0x16/0x20 [25338.606443] process_one_work+0x1a7/0x360 [25338.610456] ? create_worker+0x1a0/0x1a0 [25338.614381] worker_thread+0x1cf/0x390 [25338.618132] ? create_worker+0x1a0/0x1a0 [25338.622051] kthread+0x116/0x130 [25338.625283] ? kthread_flush_work_fn+0x10/0x10 [25338.629731] ret_from_fork+0x1f/0x40 [25338.633395] virtio_blk: probe of virtio418 failed with error -16 The log : "genirq: Flags mismatch irq 0. 00000080 (virtio418) vs. 00015a00 (timer)" was printed because of the irq 0 is used by timer exclusive,and when vp_find_vqs call vp_find_vqs_msix and returns false twice (for whatever reason), then it will call vp_find_vqs_intx as a fallback. Because vp_dev->pci_dev->irq is zero, we request irq 0 with flag IRQF_SHARED, and get a backtrace like above. According to PCI spec about "Interrupt Pin" Register (Offset 3Dh): "The Interrupt Pin register is a read-only register that identifies the legacy interrupt Message(s) the Function uses. Valid values are 01h, 02h, 03h, and 04h that map to legacy interrupt Messages for INTA, INTB, INTC, and INTD respectively. A value of 00h indicates that the Function uses no legacy interrupt Message(s)." So if vp_dev->pci_dev->pin is zero, we should not request legacy interrupt.

vDPA: conditionally read MTU and MAC in dev cfg space
The spec says: mtu only exists if VIRTIO_NET_F_MTU is set The mac address field always exists (though is only valid if VIRTIO_NET_F_MAC is set) So vdpa_dev_net_config_fill() should read MTU and MAC conditionally on the feature bits.
