7445b2dcd7 Fix for the SLS mitigation, which makes a "SETcc/RET" pair grow to
"SETcc/RET/INT3".  This doesn't fit anymore in 4 bytes, so the

fe83f5eae4 kvm/emulate: Fix SETcc emulation function offsets with SLS
The commit in Fixes started adding INT3 after RETs as a mitigation
against straight-line speculation.

The fastop SETcc implementation in kvm's insn emulator uses macro magic
to generate all possible SETcc functions and to jump to them when
emulating the respective instruction.

However, it hardcodes the size and alignment of those functions to 4: a
three-byte SETcc insn and a single-byte RET. BUT, with SLS, there's an
INT3 that gets slapped after the RET, which brings the whole scheme out
of alignment:

  15:   0f 90 c0                seto   %al
  18:   c3                      ret
  19:   cc                      int3
  1a:   0f 1f 00                nopl   (%rax)
  1d:   0f 91 c0                setno  %al
  20:   c3                      ret
  21:   cc                      int3
  22:   0f 1f 00                nopl   (%rax)
  25:   0f 92 c0                setb   %al
  28:   c3                      ret
  29:   cc                      int3

and this explodes like this:

14702b3b24 ARM: SoC fix for 5.17, part 4
Here is one last regression fix for 5.17, reverting a patch
 that went into 5.16 as a cleanup that ended up breaking
 external interrupts on Layerscape chips.
 
 The revert makes it work again, but also reintroduces a
 build time warning about the nonstandard DT binding that
 will have to be dealt with in the future.

3cf6a32f3f perf symbols: Fix symbol size calculation condition
Before this patch, the symbol end address fixup to be called, needed two
conditions being met:

  if (prev->end == prev->start && prev->end != curr->start)

Where
  "prev->end == prev->start" means that prev is zero-long
                             (and thus needs a fixup)
and
  "prev->end != curr->start" means that fixup hasn't been applied yet

However, this logic is incorrect in the following situation:

*curr  = {rb_node = {__rb_parent_color = 278218928,
  rb_right = 0x0, rb_left = 0x0},
  start = 0xc000000000062354,
  end = 0xc000000000062354, namelen = 40, type = 2 '\002',
  binding = 0 '\000', idle = 0 '\000', ignore = 0 '\000',
  inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false,
  name = 0x1159739e "kprobe_optinsn_page\t[__builtin__kprobes]"}

*prev = {rb_node = {__rb_parent_color = 278219041,
  rb_right = 0x109548b0, rb_left = 0x109547c0},
  start = 0xc000000000062354,
  end = 0xc000000000062354, namelen = 12, type = 2 '\002',
  binding = 1 '\001', idle = 0 '\000', ignore = 0 '\000',
  inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false,
  name = 0x1095486e "optinsn_slot"}

In this case, prev->start == prev->end == curr->start == curr->end,
thus the condition above thinks that "we need a fixup due to zero
length of prev symbol, but it has been probably done, since the
prev->end == curr->start", which is wrong.

After the patch, the execution path proceeds to arch__symbols__fixup_end
function which fixes up the size of prev symbol by adding page_size to
its end offset.

1c4debc443 selftests: vm: fix clang build error multiple output files
When building the vm selftests using clang, some errors are seen due to
having headers in the compilation command:

  clang -Wall -I ../../../../usr/include  -no-pie    gup_test.c ../../../../mm/gup_test.h -lrt -lpthread -o .../tools/testing/selftests/vm/gup_test
  clang: error: cannot specify -o when generating multiple output files
  make[1]: *** [../lib.mk:146: .../tools/testing/selftests/vm/gup_test] Error 1

Rework to add the header files to LOCAL_HDRS before including ../lib.mk,
since the dependency is evaluated in '$(OUTPUT)/%:%.c $(LOCAL_HDRS)' in
file lib.mk.

7b0b1332cf ocfs2: fix crash when initialize filecheck kobj fails
Once s_root is set, genric_shutdown_super() will be called if
fill_super() fails.  That means, we will call ocfs2_dismount_volume()
twice in such case, which can lead to kernel crash.

Fix this issue by initializing filecheck kobj before setting s_root.

8208257d2d configs/debug: restore DEBUG_INFO=y for overriding
Previously, I failed to realize that Kees' patch [1] has not been merged
into the mainline yet, and dropped DEBUG_INFO=y too eagerly from the
mainline.  As the results, "make debug.config" won't be able to flip
DEBUG_INFO=n from the existing .config.  This should close the gaps of a
few weeks before Kees' patch is there, and work regardless of their
merging status anyway.

029c4628b2 mm: swap: get rid of livelock in swapin readahead
In our testing, a livelock task was found.  Through sysrq printing, same
stack was found every time, as follows:

  __swap_duplicate+0x58/0x1a0
  swapcache_prepare+0x24/0x30
  __read_swap_cache_async+0xac/0x220
  read_swap_cache_async+0x58/0xa0
  swapin_readahead+0x24c/0x628
  do_swap_page+0x374/0x8a0
  __handle_mm_fault+0x598/0xd60
  handle_mm_fault+0x114/0x200
  do_page_fault+0x148/0x4d0
  do_translation_fault+0xb0/0xd4
  do_mem_abort+0x50/0xb0

The reason for the livelock is that swapcache_prepare() always returns
EEXIST, indicating that SWAP_HAS_CACHE has not been cleared, so that it
cannot jump out of the loop.  We suspect that the task that clears the
SWAP_HAS_CACHE flag never gets a chance to run.  We try to lower the
priority of the task stuck in a livelock so that the task that clears
the SWAP_HAS_CACHE flag will run.  The results show that the system
returns to normal after the priority is lowered.

In our testing, multiple real-time tasks are bound to the same core, and
the task in the livelock is the highest priority task of the core, so
the livelocked task cannot be preempted.

Although cond_resched() is used by __read_swap_cache_async, it is an
empty function in the preemptive system and cannot achieve the purpose
of releasing the CPU.  A high-priority task cannot release the CPU
unless preempted by a higher-priority task.  But when this task is
already the highest priority task on this core, other tasks will not be
able to be scheduled.  So we think we should replace cond_resched() with
schedule_timeout_uninterruptible(1), schedule_timeout_interruptible will
call set_current_state first to set the task state, so the task will be
removed from the running queue, so as to achieve the purpose of giving
up the CPU and prevent it from running in kernel mode for too long.

(akpm: ugly hack becomes uglier.  But it fixes the issue in a
backportable-to-stable fashion while we hopefully work on something
better)

b04683ff8f iavf: Fix hang during reboot/shutdown
Recent commit 974578017f ("iavf: Add waiting so the port is
initialized in remove") adds a wait-loop at the beginning of
iavf_remove() to ensure that port initialization is finished
prior unregistering net device. This causes a regression
in reboot/shutdown scenario because in this case callback
iavf_shutdown() is called and this callback detaches the device,
makes it down if it is running and sets its state to __IAVF_REMOVE.
Later shutdown callback of associated PF driver (e.g. ice_shutdown)
is called. That callback calls among other things sriov_disable()
that calls indirectly iavf_remove() (see stack trace below).
As the adapter state is already __IAVF_REMOVE then the mentioned
loop is end-less and shutdown process hangs.

The patch fixes this by checking adapter's state at the beginning
of iavf_remove() and skips the rest of the function if the adapter
is already in remove state (shutdown is in progress).

Reproducer:
1. Create VF on PF driven by ice or i40e driver
2. Ensure that the VF is bound to iavf driver
3. Reboot

8e0341aefc net: mscc: ocelot: fix backwards compatibility with single-chain tc-flower offload
ACL rules can be offloaded to VCAP IS2 either through chain 0, or, since
the blamed commit, through a chain index whose number encodes a specific
PAG (Policy Action Group) and lookup number.

The chain number is translated through ocelot_chain_to_pag() into a PAG,
and through ocelot_chain_to_lookup() into a lookup number.

The problem with the blamed commit is that the above 2 functions don't
have special treatment for chain 0. So ocelot_chain_to_pag(0) returns
filter->pag = 224, which is in fact -32, but the "pag" field is an u8.

So we end up programming the hardware with VCAP IS2 entries having a PAG
of 224. But the way in which the PAG works is that it defines a subset
of VCAP IS2 filters which should match on a packet. The default PAG is
0, and previous VCAP IS1 rules (which we offload using 'goto') can
modify it. So basically, we are installing filters with a PAG on which
no packet will ever match. This is the hardware equivalent of adding
filters to a chain which has no 'goto' to it.

Restore the previous functionality by making ACL filters offloaded to
chain 0 go to PAG 0 and lookup number 0. The choice of PAG is clearly
correct, but the choice of lookup number isn't "as before" (which was to
leave the lookup a "don't care"). However, lookup 0 should be fine,
since even though there are ACL actions (policers) which have a
requirement to be used in a specific lookup, that lookup is 0.

424e7834e2 bnx2x: fix built-in kernel driver load failure
Commit b7a49f7305 ("bnx2x: Utilize firmware 7.13.21.0")
added request_firmware() logic in probe() which caused
load failure when firmware file is not present in initrd (below),
as access to firmware file is not feasible during probe.

  Direct firmware load for bnx2x/bnx2x-e2-7.13.15.0.fw failed with error -2
  Direct firmware load for bnx2x/bnx2x-e2-7.13.21.0.fw failed with error -2

This patch fixes this issue by -

1. Removing request_firmware() logic from the probe()
   such that .ndo_open() handle it as it used to handle
   it earlier

2. Given request_firmware() is removed from probe(), so
   driver has to relax FW version comparisons a bit against
   the already loaded FW version (by some other PFs of same
   adapter) to allow different compatible/close enough FWs with which
   multiple PFs may run with (in different environments), as the
   given PF who is in probe flow has no idea now with which firmware
   file version it is going to initialize the device in ndo_open()

This happens if panel-edp.ko has been configured with

  DRM_PANEL_EDP=y
  DRM_DP_HELPER=y
  DRM_KMS_HELPER=m

which builds DP helpers into the kernel and KMS helpers sa a module.
Making DRM_PANEL_EDP select DRM_KMS_HELPER resolves this problem.

To avoid a resulting cyclic dependency with DRM_PANEL_BRIDGE, don't
make the latter depend on DRM_KMS_HELPER and fix the one DRM bridge
drivers that doesn't already select DRM_KMS_HELPER. As KMS helpers
cannot be selected directly by the user, config symbols should avoid
depending on it anyway.

Revert "arm64: dts: freescale: Fix 'interrupt-map' parent address cells"
This reverts commit 869f0ec048. That
updated the expected device tree binding format for the ls-extirq
driver, without also updating the parsing code (ls_extirq_parse_map)
to the new format.

The context is that the ls-extirq driver uses the standard
"interrupt-map" OF property in a non-standard way, as suggested by
Rob Herring during review:
https://lore.kernel.org/lkml/20190927161118.GA19333@bogus/

This has turned out to be problematic, as Marc Zyngier discovered
through commit 0412841812 ("of/irq: Allow matching of an interrupt-map
local to an interrupt controller"), later fixed through commit
de4adddcbc ("of/irq: Add a quirk for controllers with their own
definition of interrupt-map"). Marc's position, expressed on multiple
opportunities, is that:

(a) [ making private use of the reserved "interrupt-map" name in a
    driver ] "is wrong, by the very letter of what an interrupt-map
    means. If the interrupt map points to an interrupt controller,
    that's the target for the interrupt."
https://lore.kernel.org/lkml/87k0g8jlmg.wl-maz@kernel.org/

(b) [ updating the driver's bindings to accept a non-reserved name for
    this property, as an alternative, is ] "is totally pointless. These
    machines have been in the wild for years, and existing DTs will be
    there *forever*."
https://lore.kernel.org/lkml/87ilvrk1r0.wl-maz@kernel.org/

Considering the above, the Linux kernel has quirks in place to deal with
the ls-extirq's non-standard use of the "interrupt-map". These quirks
may be needed in other operating systems that consume this device tree,
yet this is seen as the only viable solution.

Therefore, the premise of the patch being reverted here is invalid.
It doesn't matter whether the driver, in its non-standard use of the
property, complies to the standard format or not, since this property
isn't expected to be used for interrupt translation by the core.

This change restores LS1088A, LS2088A/LS2085A and LX2160A to their
previous bindings, which allows these systems to continue to use
external interrupt lines with the correct polarity.

original commit fe141cedc4 does not explain why this
check was introduced. So remove the bus flags check,
because it stops the initialization of the display with
valid bus flags.

Fixes: fe141cedc4 ("drm/imx: pd: Use bus format/flags provided by the bridge when available")

45b4eb7ee6 Revert "ath10k: drop beacon and probe response which leak from other channel"
This reverts commit 3bf2537ec2.

I was reported privately that this commit breaks AP and mesh mode on QCA9984
(firmware 10.4-3.9.0.2-00156). So revert the commit to fix the regression.

There was a conflict due to cfg80211 API changes but that was easy to fix.

Revert commit e38f9ff63e ("ACPI: scan: Do not add device IDs from _CID

Intel Wired LAN Driver Updates 2022-03-15

This series contains updates to ice and iavf drivers.

Maciej adjusts null check logic on Tx ring to prevent possible NULL
pointer dereference for ice.

Sudheer moves destruction of Flow Director lock as it was being accessed
after destruction for ice.

Przemyslaw removes an excess mutex unlock as it was being double
unlocked for iavf.

886e44c929 hv_netvsc: Add check for kvmalloc_array
As the potential failure of the kvmalloc_array(),
it should be better to check and restore the 'data'

NULL pointer.

16b2dd8cdf iavf: Fix double free in iavf_reset_task
Fix double free possibility in iavf_disable_vf, as crit_lock is
freed in caller, iavf_reset_task. Add kernel-doc for iavf_disable_vf.
Remove mutex_unlock in iavf_disable_vf.
Without this patch there is double free scenario, when calling
iavf_reset_task.

f153546913 ice: fix NULL pointer dereference in ice_update_vsi_tx_ring_stats()
It is possible to do NULL pointer dereference in routine that updates
Tx ring stats. Currently only stats and bytes are updated when ring
pointer is valid, but later on ring is accessed to propagate gathered Tx
stats onto VSI stats.

Change the existing logic to move to next ring when ring is NULL.
