4ba1329cbb Urgent RCU pull request for v5.19
This pull request contains a pair of commits that fix 282d8998e9 ("srcu:
 Prevent expedited GPs and blocking readers from consuming CPU"), which
 was itself a fix to an SRCU expedited grace-period problem that could
 prevent kernel live patching (KLP) from completing.  That SRCU fix for
 KLP introduced large (as in minutes) boot-time delays to embedded Linux
 kernels running on qemu/KVM.  These delays were due to the emulation of
 certain MMIO operations controlling memory layout, which were emulated
 with one expedited grace period per access.  Common configurations
 required thousands of boot-time MMIO accesses, and thus thousands of
 boot-time expedited SRCU grace periods.
 
 In these configurations, the occasional sleeps that allowed KLP to proceed
 caused excessive boot delays.  These commits preserve enough sleeps to
 permit KLP to proceed, but few enough that the virtual embedded kernels
 still boot reasonably quickly.
 
 This represents a regression introduced in the v5.19 merge window,
 and the bug is causing significant inconvenience, hence this pull request.

7fb5e50831 mmu_gather: fix the CONFIG_MMU_GATHER_NO_RANGE case
Sudip reports that alpha doesn't build properly, with errors like

  include/asm-generic/tlb.h:401:1: error: redefinition of 'tlb_update_vma_flags'
    401 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma)
        | ^~~~~~~~~~~~~~~~~~~~
  include/asm-generic/tlb.h:372:1: note: previous definition of 'tlb_update_vma_flags' with type 'void(struct mmu_gather *, struct vm_area_struct *)'
    372 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma) { }

the cause being that We have this odd situation where some architectures
were never converted to the newer TLB flushing interfaces that have a
range for the flush.  Instead people left them alone, and we have them
select the MMU_GATHER_NO_RANGE config option to make the tlb header
files account for this.

Peter Zijlstra cleaned some of these nasty header file games up in
commits

  1e9fdf21a4 ("mmu_gather: Remove per arch tlb_{start,end}_vma()")
  18ba064e42 ("mmu_gather: Let there be one tlb_{start,end}_vma() implementation")

but tlb_update_vma_flags() was left alone, and then commit b67fbebd4c
("mmu_gather: Force tlb-flush VM_PFNMAP vmas") ended up removing only
_one_ of the two stale duplicate dummy inline functions.

This removes the other stale one.

Somebody braver than me should try to remove MMU_GATHER_NO_RANGE
entirely, but it requires fixing up the oddball architectures that use
it: alpha, m68k, microblaze, nios2 and openrisc.

The fixups should be fairly straightforward ("fix the build errors it
exposes by adding the appropriate range arguments"), but the reason this
wasn't done in the first place is that so few people end up working on
those architectures.  But it could be done one architecture at a time,
hint, hint.

fa9482e0b2 ublk_drv: fix error handling of ublk_add_dev
__ublk_destroy_dev() is called for handling error in ublk_add_dev(),
but either tagset isn't allocated or mutex isn't initialized.

So fix the issue by letting replacing ublk_add_dev with a
ublk_add_tag_set function that is much more limited in scope and
instead unwind every single step directly in ublk_ctrl_add_dev.
To allow for this refactor the device freeing so that there is
a helper for freeing the device number instead of coupling that
with freeing the mutex and the memory.

Note that this now copies the dev_info to userspace before adding
the character device.  This not only simplifies the erro handling
in ublk_ctrl_add_dev, but also means that the character device
can only be seen by userspace if the device addition succeeded.

Based on a patch from Ming Lei.

Let's introduce multi-reference pclusters at runtime. In details,
if one pcluster is requested by multiple extents at almost the same
time (even belong to different files), the longest extent will be
decompressed as representative and the other extents are actually
copied from the longest one in one round.

After this patch, fully-referenced extents can be correctly handled
and the full decoding check needs to be bypassed for
partial-referenced extents.

eaa225b6b5 drm/komeda: Fix handling of atomic commits in the atomic_commit_tail hook
Komeda driver relies on the generic DRM atomic helper functions to handle
commits. It only implements an atomic_commit_tail hook for the
mode_config_helper_funcs and even that one is pretty close to the generic
implementation with the exception of additional dma_fence signalling.

What the generic helper framework doesn't do is waiting for the actual
hardware to signal that the commit parameters have been written into the
appropriate registers. As we signal CRTC events only on the irq handlers,
we need to flush the configuration and wait for the hardware to respond.

Add the Komeda specific implementation for atomic_commit_hw_done() that
flushes and waits for flip done before calling drm_atomic_helper_commit_hw_done().

The fix was prompted by a patch from Carsten Haitzler where he was trying to
solve the same issue but in a different way that I think can lead to wrong
event signaling to userspace.

ARM: pxa2xx: Fix GPIO descriptor tables
Laurence reports:

"Kernel >5.18 on Zaurus has a bug where the power management code can't
talk to devices, emitting the following errors:

sharpsl-pm sharpsl-pm: Error: AC check failed: voltage -22.
sharpsl-pm sharpsl-pm: Charging Error!
sharpsl-pm sharpsl-pm: Warning: Cannot read main battery!

Looking at the recent changes, I found that commit 31455bbda2 ("spi:
pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated
SPI chip select platform device code with a gpiod lookup table. However,
this didn't seem to work until I changed the `dev_id` member from the
device name to the bus id. I'm not entirely sure why this is necessary,
but I suspect it is related to the fact that in sysfs SPI devices are
attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather
than directly to the device."

After reviewing the change I conclude that the same fix is needed
for all affected boards.

asm-generic: remove a broken and needless ifdef conditional
Commit 527701eda5 ("lib: Add a generic version of devmem_is_allowed()")
introduces the config symbol GENERIC_LIB_DEVMEM_IS_ALLOWED, but then
falsely refers to CONFIG_GENERIC_DEVMEM_IS_ALLOWED (note the missing LIB
in the reference) in ./include/asm-generic/io.h.

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:

GENERIC_DEVMEM_IS_ALLOWED
Referencing files: include/asm-generic/io.h

The actual fix, though, is simply to not to make this function declaration
dependent on any kernel config. For architectures that intend to use
the generic version, the arch's 'select GENERIC_LIB_DEVMEM_IS_ALLOWED' will
lead to picking the function definition, and for other architectures, this
function is simply defined elsewhere.

The wrong '#ifndef' on a non-existing config symbol also always had the
same effect (although more by mistake than by intent). So, there is no
functional change.

Remove this broken and needless ifdef conditional.

ASoC: Intel: avs: Use lookup table to create modules
As reported by Nathan, when building avs driver using clang with:
  CONFIG_COMPILE_TEST=y
  CONFIG_FORTIFY_SOURCE=y
  CONFIG_KASAN=y
  CONFIG_PCI=y
  CONFIG_SOUND=y
  CONFIG_SND=y
  CONFIG_SND_SOC=y
  CONFIG_SND_SOC_INTEL_AVS=y

there are reports of too big stack use, like:
  sound/soc/intel/avs/path.c:815:18: error: stack frame size (2176) exceeds limit (2048) in 'avs_path_create' [-Werror,-Wframe-larger-than]
  struct avs_path *avs_path_create(struct avs_dev *adev, u32 dma_id,
                   ^
  1 error generated.

This is apparently caused by inlining many calls to guid_equal which
inlines fortified memcpy, using 2 size_t variables.

Instead of hardcoding many calls to guid_equal, use lookup table with
one call, this improves stack usage.

ASoC: amd: vangogh: Use non-legacy DAI naming for cs35l41
Unlike most CODEC drivers, the CS35L41 driver did not have the
non_legacy_dai_naming set, meaning the corresponding DAI has been
traditionally registered using the legacy naming: spi-VLV1776:0x

The recent migration to the new legacy DAI naming style has implicitly
corrected that behavior and DAI gets now registered via the non-legacy
naming, i.e. cs35l41-pcm.

The problem is the acp5x platform driver is now broken as it continues
to refer to the above mentioned codec using the legacy DAI naming in
function acp5x_cs35l41_hw_params() and, therefore, the related setup
is not being executed anymore.

Let's fix that by replacing the obsolete DAI name with the correct one.
