When recording with cache-misses and arm_spe_x event, I found that it
will just fail without showing any error info if i put cache-misses
after 'arm_spe_x' event.

  [root@localhost 0620]# perf record -e cache-misses \
				-e arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.067 MB perf.data ]

  [root@localhost 0620]# perf record -e arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ \
				     -e  cache-misses sleep 1
  [root@localhost 0620]#

The current code can only work if the only event to be traced is an
'arm_spe_x', or if it is the last event to be specified. Otherwise the
last event type will be checked against all the arm_spe_pmus[i]->types,
none will match and an out of bound 'i' index will be used in
arm_spe_recording_init().

We don't support concurrent multiple arm_spe_x events currently, that
is checked in arm_spe_recording_options(), and it will show the relevant
info. So add the check and record of the first found 'arm_spe_pmu' to
fix this issue here.

Commit 5aa98879 ("s390/cpum_sf: prohibit callchain data collection")
prohibits call graph sampling for hardware events on s390. The
information recorded is out of context and does not match.

On s390 this commit now breaks test case 68 Zstd perf.data

Therefore omit call graph sampling on s390 in this test.

Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()
family of modifiers to handle broken userspace
Xorg modesetting and Mesa drivers. Existing Mesa
drivers are still aware of only these older
format modifiers which do not differentiate
between different variations of the block linear
layout. When the format modifier support flag was
flipped in the nouveau kernel driver, the X.org
modesetting driver began attempting to use its
format modifier-enabled framebuffer path. Because
the set of format modifiers advertised by the
kernel prior to this change do not intersect with
the set of format modifiers advertised by Mesa,
allocating GBM buffers using format modifiers
fails and the modesetting driver falls back to
non-modifier allocation. However, it still later
queries the modifier of the GBM buffer when
creating its DRM-KMS framebuffer object, receives
the old-format modifier from Mesa, and attempts
to create a framebuffer with it. Since the kernel
is still not aware of these formats, this fails.

Userspace should not be attempting to query format
modifiers of GBM buffers allocated with a non-
format-modifier-aware allocation path, but to
avoid breaking existing userspace behavior, this
change accepts the old-style format modifiers when
creating framebuffers and applying them to planes
by translating them to the equivalent new-style
modifier. To accomplish this, some layout
parameters must be assumed to match properties of
the device targeted by the relevant ioctls. To
avoid perpetuating misuse of the old-style
modifiers, this change does not advertise support
for them. Doing so would imply compatibility
between devices with incompatible memory layouts.

Tested with Xorg 1.20 modesetting driver,

Fix kernel oops observed when an ext adv data is larger than 31 bytes.

This can be reproduced by setting up an advertiser with advertisement
larger than 31 bytes.  The issue is not sensitive to the advertisement
content.  In particular, this was reproduced with an advertisement of
229 bytes filled with 'A'.  See stack trace below.

This is fixed by not catching ext_adv as legacy adv are only cached to
be able to concatenate a scanable adv with its scan response before
sending it up through mgmt.

With ext_adv, this is no longer necessary.

  io_uring: fix ->work corruption with poll_add

Daniel Díaz and Kees Cook independently reported that commit
f227e3ec ("random32: update the net random state on interrupt and
activity") broke arm64 due to a circular dependency on include files
since the addition of percpu.h in random.h.

The correct fix would definitely be to move all the prandom32 stuff out
of random.h but for backporting, a smaller solution is preferred.

This one replaces linux/percpu.h with asm/percpu.h, and this fixes the
problem on x86_64, arm64, arm, and mips.  Note that moving percpu.h
around didn't change anything and that removing it entirely broke
differently.  When backporting, such options might still be considered
if this patch fails to help.

[ It turns out that an alternate fix seems to be to just remove the
  troublesome <asm/pointer_auth.h> remove from the arm64 <asm/smp.h>
  that causes the circular dependency.

  But we might as well do the whole belt-and-suspenders thing, and
  minimize inclusion in <linux/random.h> too. Either will fix the
  problem, and both are good changes.   - Linus ]

Commit f7b93d42 ("arm64/alternatives: use subsections for replacement
sequences") breaks LLVM's integrated assembler, because due to its
one-pass design, it cannot compute instruction sequence lengths before the
layout for the subsection has been finalized. This change fixes the build
by moving the .org directives inside the subsection, so they are processed
after the subsection layout is known.

This patch fixes a race condition that causes a use-after-free during
amdgpu_dm_atomic_commit_tail. This can occur when 2 non-blocking commits
are requested and the second one finishes before the first. Essentially,
this bug occurs when the following sequence of events happens:

1. Non-blocking commit #1 is requested w/ a new dm_state #1 and is
deferred to the workqueue.

2. Non-blocking commit #2 is requested w/ a new dm_state #2 and is
deferred to the workqueue.

3. Commit #2 starts before commit #1, dm_state #1 is used in the
commit_tail and commit #2 completes, freeing dm_state #1.

4. Commit #1 starts after commit #2 completes, uses the freed dm_state
1 and dereferences a freelist pointer while setting the context.

Since this bug has only been spotted with fast commits, this patch fixes
the bug by clearing the dm_state instead of using the old dc_state for
fast updates. In addition, since dm_state is only used for its dc_state
and amdgpu_dm_atomic_commit_tail will retain the dc_state if none is found,
removing the dm_state should not have any consequences in fast updates.

This use-after-free bug has existed for a while now, but only caused a
noticeable issue starting from 5.7-rc1 due to 3202fa62 ("slub: relocate
freelist pointer to middle of object") moving the freelist pointer from
dm_state->base (which was unused) to dm_state->context (which is
dereferenced).

Compiler leaves a 4-byte hole near the end of `dev_info`, causing
amdgpu_info_ioctl() to copy uninitialized kernel stack memory to userspace
when `size` is greater than 356.

In 2015 we tried to fix this issue by doing `= {};` on `dev_info`, which
unfortunately does not initialize that 4-byte hole. Fix it by using
memset() instead.

It turns out that the plugin right now ends up being really unhappy

This is probably a trivial fix for the latent_entropy plugin, but for
now, just remove net_rand_state from the list of things the plugin
worries about.

Recently ASPM handling was changed to allow ASPM on PCIe-to-PCI/PCI-X
bridges.  Unfortunately the ASMedia ASM1083/1085 PCIe to PCI bridge device
doesn't seem to function properly with ASPM enabled.  On an Asus PRIME
H270-PRO motherboard, it causes errors like these:

  pcieport 0000:00:1c.0: AER: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Transmitter ID)
  pcieport 0000:00:1c.0: AER:   device [8086:a292] error status/mask=00003000/00002000
  pcieport 0000:00:1c.0: AER:    [12] Timeout
  pcieport 0000:00:1c.0: AER: Corrected error received: 0000:00:1c.0
  pcieport 0000:00:1c.0: AER: can't find device of ID00e0

In addition to flooding the kernel log, this also causes the machine to
wake up immediately after suspend is initiated.

The device advertises ASPM L0s and L1 support in the Link Capabilities
register, but the ASMedia web page for ASM1083 [1] claims "No PCIe ASPM
support".

Windows 10 (build 2004) enables L0s, but it also logs correctable PCIe
errors.

Add a quirk to disable ASPM for this device.

The lookaside count is improperly initialized to the size of the
Receive Queue with the additional +1.  In the traces below, the
RQ size is 384, so the count was set to 385.

The lookaside count is then rarely refreshed.  Note the high and
incorrect count in the trace below:

rvt_get_rwqe: [hfi1_0] wqe ffffc900078e9008 wr_id 55c7206d75a0 qpn c
	qpt 2 pid 3018 num_sge 1 head 1 tail 0, count 385
rvt_get_rwqe: (hfi1_rc_rcv+0x4eb/0x1480 [hfi1] <- rvt_get_rwqe) ret=0x1

The head,tail indicate there is only one RWQE posted although the count
says 385 and we correctly return the element 0.

The next call to rvt_get_rwqe with the decremented count:

rvt_get_rwqe: [hfi1_0] wqe ffffc900078e9058 wr_id 0 qpn c
	qpt 2 pid 3018 num_sge 0 head 1 tail 1, count 384
rvt_get_rwqe: (hfi1_rc_rcv+0x4eb/0x1480 [hfi1] <- rvt_get_rwqe) ret=0x1

Note that the RQ is empty (head == tail) yet we return the RWQE at tail 1,
which is not valid because of the bogus high count.

Best case, the RWQE has never been posted and the rc logic sees an RWQE
that is too small (all zeros) and puts the QP into an error state.

In the worst case, a server slow at posting receive buffers might fool
rvt_get_rwqe() into fetching an old RWQE and corrupt memory.

Fix by deleting the faulty initialization code and creating an
inline to fetch the posted count and convert all callers to use
new inline.
