a6a87c3616 Input: i8042 - add TUXEDO devices to i8042 quirk tables
A lot of modern Clevo barebones have touchpad and/or keyboard issues after
suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them
have an external PS/2 port so this can safely be set for all of them.

I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use. No negative effects could be
observed when setting all four.

The list is quite massive as neither the TUXEDO nor the Clevo dmi strings
have been very consistent historically. I tried to keep the list as short
as possible without risking on missing an affected device.

This is revision 3. The Clevo N150CU barebone is still removed as it might
have problems with the fix and needs further investigations. The
SchenkerTechnologiesGmbH System-/Board-Vendor string variations are
added. This is now based in the quirk table refactor. This now also
includes the additional noaux flag for the NS7xMU.

Make new quirk table easily debugable with some debug output.

With no functional change, evaluation of i8042_reset_quirk and
i8042_reset_never_quirk had to be moved for this.

ff946268a0 Input: i8042 - merge quirk tables
Merge i8042 quirk tables to reduce code duplication for devices that need
more than one quirk. Before every quirk had its own table with devices
needing that quirk. If a new quirk needed to be added a new table had to
be created. When a device needed multiple quirks, it appeared in multiple
tables. Now only one table called i8042_dmi_quirk_table exists. In it every
device has one entry and required quirks are coded in the .driver_data
field of the struct dmi_system_id used by this table. Multiple quirks for
one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines.

Also align quirkable options with command line parameters and make vendor
wide quirks per device overwriteable on a per device basis. The first match
is honored while following matches are ignored. So when a vendor wide quirk
is defined in the table, a device can inserted before and therefore
ignoring the vendor wide define.

Currently, the response to the power cap command overwrites the
first eight bytes of the poll response, since the commands use
the same buffer. This means that user's get the wrong data between
the time of sending the power cap and the next poll response update.
Fix this by specifying a different buffer for the power cap command
response.

b5d281f6c1 PM / devfreq: Rework freq_table to be local to devfreq struct
On a devfreq PROBE_DEFER, the freq_table in the driver profile struct,
is never reset and may be leaved in an undefined state.

This comes from the fact that we store the freq_table in the driver
profile struct that is commonly defined as static and not reset on
PROBE_DEFER.
We currently skip the reinit of the freq_table if we found
it's already defined since a driver may declare his own freq_table.

This logic is flawed in the case devfreq core generate a freq_table, set
it in the profile struct and then PROBE_DEFER, freeing the freq_table.
In this case devfreq will found a NOT NULL freq_table that has been
freed, skip the freq_table generation and probe the driver based on the
wrong table.

To fix this and correctly handle PROBE_DEFER, use a local freq_table and
max_state in the devfreq struct and never modify the freq_table present
in the profile struct if it does provide it.

0cca7e8dcf PM / devfreq: Fix cpufreq passive unregister erroring on PROBE_DEFER
With the passive governor, the cpu based scaling can PROBE_DEFER due to
the fact that CPU policy are not ready.
The cpufreq passive unregister notifier is called both from the
GOV_START errors and for the GOV_STOP and assume the notifier is
successfully registred every time. With GOV_START failing it's wrong to
loop over each possible CPU since the register path has failed for
some CPU policy not ready. Change the logic and unregister the notifer
based on the current allocated parent_cpu_data list to correctly handle
errors and the governor unregister path.

struct is freed and then reallocaed on probe retry.

20b8264394 drm/fourcc: fix integer type usage in uapi header
Kernel uapi headers are supposed to use __[us]{8,16,32,64} types defined
by <linux/types.h> as opposed to 'uint32_t' and similar. See [1] for the
relevant discussion about this topic. In this particular case, the usage
of 'uint64_t' escaped headers_check as these macros are not being called
here. However, the following program triggers a compilation error:

  #include <drm/drm_fourcc.h>

  int main()
  {
  	unsigned long x = AMD_FMT_MOD_CLEAR(RB);
  	return 0;
  }

gcc error:
  drm.c:5:27: error: ‘uint64_t’ undeclared (first use in this function)

This patch changes AMD_FMT_MOD_{SET,CLEAR} macros to use the correct
integer types, which fixes the above issue.

8944c6fb8a xfs: dont treat rt extents beyond EOF as eofblocks to be cleared
On a system with a realtime volume and a 28k realtime extent,
generic/491 fails because the test opens a file on a frozen filesystem
and closing it causes xfs_release -> xfs_can_free_eofblocks to
mistakenly think that the the blocks of the realtime extent beyond EOF
are posteof blocks to be freed.  Realtime extents cannot be partially
unmapped, so this is pointless.  Worse yet, this triggers posteof
cleanup, which stalls on a transaction allocation, which is why the test
fails.

Teach the predicate to account for realtime extents properly.

e53bcffad0 xfs: don't hold xattr leaf buffers across transaction rolls
Now that we've established (again!) that empty xattr leaf buffers are
ok, we no longer need to bhold them to transactions when we're creating
new leaf blocks.  Get rid of the entire mechanism, which should simplify
the xattr code quite a bit.

The original justification for using bhold here was to prevent the AIL
from trying to write the empty leaf block into the fs during the brief
time that we release the buffer lock.  The reason for /that/ was to
prevent recovery from tripping over the empty ondisk block.

7be3bd8856 xfs: empty xattr leaf header blocks are not corruption
TLDR: Revert commit 51e6104fdb95 ("xfs: detect empty attr leaf blocks in
xfs_attr3_leaf_verify") because it was wrong.

Every now and then we get a corruption report from the kernel or
xfs_repair about empty leaf blocks in the extended attribute structure.
We've long thought that these shouldn't be possible, but prior to 5.18
one would shake loose in the recoveryloop fstests about once a month.

A new addition to the xattr leaf block verifier in 5.19-rc1 makes this
happen every 7 minutes on my testing cloud.  I added a ton of logging to
detect any time we set the header count on an xattr leaf block to zero.
This produced the following dmesg output on generic/388:

XFS (sda4): ino 0x21fcbaf leaf 0x129bf78 hdcount==0!

So now we know that someone is creating empty xattr leaf blocks as part
of converting a sf xattr structure into a leaf xattr structure.  The
conversion routine logs any existing sf attributes in the same
transaction that creates the leaf block, so we know this is a setxattr
to a file that has no attributes at all.

Next, g/388 calls the shutdown ioctl and cycles the mount to trigger log
recovery.  I also augmented buffer item recovery to call ->verify_struct
on any attr leaf blocks and complain if it finds a failure:

XFS (sda4): Unmounting Filesystem

I think I see what's going on here -- setxattr is racing with something
that shuts down the filesystem:

As you can see, the bhold keeps the leaf buffer locked and thus prevents
the *AIL* from tripping over the ichdr.count==0 check in the write
verifier.  Unfortunately, it doesn't prevent the log from getting
flushed to disk, which sets up log recovery to fail.

So.  It's clear that the kernel has always had the ability to persist
attr leaf blocks with ichdr.count==0, which means that it's part of the
ondisk format now.

Unfortunately, this check has been added and removed multiple times
throughout history.  It first appeared in[1] kernel 3.10 as part of the
early V5 format patches.  The check was later discovered to break log
recovery and hence disabled[2] during log recovery in kernel 4.10.
Simultaneously, the check was added[3] to xfs_repair 4.9.0 to try to
weed out the empty leaf blocks.  This was still not correct because log
recovery would recover an empty attr leaf block successfully only for
regular xattr operations to trip over the empty block during of the
block during regular operation.  Therefore, the check was removed
entirely[4] in kernel 5.7 but removal of the xfs_repair check was
forgotten.  The continued complaints from xfs_repair lead to us
mistakenly re-adding[5] the verifier check for kernel 5.19.  Remove it
once again.

[1] 517c22207b04 ("xfs: add CRCs to attr leaf blocks")
[2] 2e1d23370e75 ("xfs: ignore leaf attr ichdr.count in verifier
                   during log replay")

[5] 51e6104fdb95 ("xfs: detect empty attr leaf blocks in
                   xfs_attr3_leaf_verify")

Looking at the rest of the xattr code, it seems that files with empty
leaf blocks behave as expected -- listxattr reports no attributes;
getxattr on any xattr returns nothing as expected; removexattr does
nothing; and setxattr can add attributes just fine.

Instead of open-coding the command iov traversal, simply call
crypto_ahash_digest with the command sg that is already allocated (we
already do that for the send path). Rename nvmet_tcp_send_ddgst to
nvmet_tcp_calc_ddgst and call it from send and recv paths.

b21bd5a4b1 powerpc/bpf: Fix use of user_pt_regs in uapi
Trying to build a .c file that includes <linux/bpf_perf_event.h>:
  $ cat test_bpf_headers.c
  #include <linux/bpf_perf_event.h>

throws the below error:
  /usr/include/linux/bpf_perf_event.h:14:28: error: field ‘regs’ has incomplete type
     14 |         bpf_user_pt_regs_t regs;
	|                            ^~~~

This is because we typedef bpf_user_pt_regs_t to 'struct user_pt_regs'
in arch/powerpc/include/uaps/asm/bpf_perf_event.h, but 'struct
user_pt_regs' is not exposed to userspace.

Powerpc has both pt_regs and user_pt_regs structures. However, unlike
arm64 and s390, we expose user_pt_regs to userspace as just 'pt_regs'.
As such, we should typedef bpf_user_pt_regs_t to 'struct pt_regs' for
userspace.

Within the kernel though, we want to typedef bpf_user_pt_regs_t to
'struct user_pt_regs'.

Remove arch/powerpc/include/uapi/asm/bpf_perf_event.h so that the
uapi/asm-generic version of the header is exposed to userspace.
Introduce arch/powerpc/include/asm/bpf_perf_event.h so that we can
typedef bpf_user_pt_regs_t to 'struct user_pt_regs' for use within the
kernel.

Note that this was not showing up with the bpf selftest build since
tools/include/uapi/asm/bpf_perf_event.h didn't include the powerpc
variant.

fbdev: Disable sysfb device registration when removing conflicting FBs
The platform devices registered by sysfb match with firmware-based DRM or
fbdev drivers, that are used to have early graphics using a framebuffer
provided by the system firmware.

DRM or fbdev drivers later are probed and remove conflicting framebuffers,
leading to these platform devices for generic drivers to be unregistered.

But the current solution has a race, since the sysfb_init() function could
be called after a DRM or fbdev driver is probed and request to unregister
the devices for drivers with conflicting framebuffes.

To prevent this, disable any future sysfb platform device registration by
calling sysfb_disable(), if a driver requests to remove the conflicting
framebuffers.

wait_for_completion_timeout() returns unsigned long not int.
It returns 0 if timed out, and positive if completed.
The check for <= 0 is ambiguous and should be == 0 here

As of commit 5801f064e351 ("net: ipv6: unexport __init-annotated seg6_hmac_init()"),
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.

This remove the EXPORT_SYMBOL to fix modpost warning:

WARNING: modpost: vmlinux.o(___ksymtab+seg6_hmac_net_init+0x0): Section mismatch in reference from the variable __ksymtab_seg6_hmac_net_init to the function .init.text:seg6_hmac_net_init()
The symbol seg6_hmac_net_init is exported and annotated __init
Fix this by removing the __init annotation of seg6_hmac_net_init or drop the export.
