4e8ff73eb7 KVM: arm64: Get sys_reg encoding from descriptor in idregs_debug_show()
KVM is about to add support for more VM-scoped feature ID regs that
live outside of the id_regs[] array, which means the index of the
debugfs iterator may not actually be an index into the array.

Prepare by getting the sys_reg encoding from the descriptor itself.

90d32e9201 tools/perf: Handle perftool-testsuite_probe testcases fail when kernel debuginfo is not present
Running "perftool-testsuite_probe" fails as below:

	./perf test -v "perftool-testsuite_probe"
	83: perftool-testsuite_probe  : FAILED

There are three fails:

1. Regexp not found: "\s*probe:inode_permission(?:_\d+)?\s+\(on inode_permission(?:[:\+][0-9A-Fa-f]+)?@.+\)"
   -- [ FAIL ] -- perf_probe :: test_adding_kernel :: listing added probe :: perf probe -l (output regexp parsing)

2. Regexp not found: "probe:vfs_mknod"
   Regexp not found: "probe:vfs_create"
   Regexp not found: "probe:vfs_rmdir"
   Regexp not found: "probe:vfs_link"
   Regexp not found: "probe:vfs_write"
   -- [ FAIL ] -- perf_probe :: test_adding_kernel :: wildcard adding support (command exitcode + output regexp parsing)

3. Regexp not found: "Failed to find"
   Regexp not found: "somenonexistingrandomstuffwhichisalsoprettylongorevenlongertoexceed64"
   Regexp not found: "in this function|at this address"
   Line did not match any pattern: "The /boot/vmlinux file has no debug information."
   Line did not match any pattern: "Rebuild with CONFIG_DEBUG_INFO=y, or install an appropriate debuginfo package."

These three tests depends on kernel debug info.
1. Fail 1 expects file name along with probe which needs debuginfo
2. Fail 2 :
    perf probe -nf --max-probes=512 -a 'vfs_* $params'
    Debuginfo-analysis is not supported.
     Error: Failed to add events.

3. Fail 3 :
   perf probe 'vfs_read somenonexistingrandomstuffwhichisalsoprettylongorevenlongertoexceed64'
   Debuginfo-analysis is not supported.
   Error: Failed to add events.

There is already helper function skip_if_no_debuginfo in
lib/probe_vfs_getname.sh which does perf probe and returns
"2" if debug info is not present. Use the skip_if_no_debuginfo
function and skip only the three tests which needs debuginfo
based on the result.

b1d90a862c drm/xe: Use the encoder suspend helper also used by the i915 driver
Use the suspend encoders helper which is also used by the i915 driver.
This fixes an issue in the xe driver where the encoder
suspend_complete() hook is not called and was an overlook when this hook
was added in commit b61fad5f7e ("drm/i915/tc: Call TypeC port
flush_work/cleanup without modeset locks held") for i915, but not added
to the xe driver (which was still in a separate source tree at the above
point).

v2: Fix checkpatch warn in commit log. (Rodrigo)

the logical place for encoder functions.

This also allows sharing the above helpers with the xe driver, done in a

While at it rename the functions using the usual intel_encoder prefix
and in the functions rename the dev_priv parameter to i915.

v2: Remove extra w/s in the include section. (Jani)

regulator: dt-bindings: mt6315: Document MT6319 PMIC
The MT6319 is a pin-compatible drop-in replacement for MT6315 with
slightly better electrical characteristics.

It's unclear whether there are any differences, since the downstream
implementation doesn't describe the MT6319 separately. Neither does the
implementation check chip IDs, even though those are available.

Add a new compatible for the MT6319 just in case differences are
discovered later and fall back to the MT6315 compatible.

variable 'mode' is of a simple 'int' type.
Change 'mode' variable type from 'int' to 'enum operation_mode_e' in
order to improve compiler type checking.
Built and tested this with different monitor cmdline params. Everything
works as expected, that is nothing changed and no regressions encountered.

a286db937e cpupower: Remove absent 'v' parameter from monitor man page
Remove not supported '-v' parameter from the cpupower's 'monitor'
command description.
There is a '-v' parameter described in cpupower's 'monitor' command man
page. It isn't supported at the moment, and perhaps has never been
supported. When I run the monitor with this parameter I get the
following:

$ sudo LD_LIBRARY_PATH=lib64/ bin/cpupower monitor -v
monitor: invalid option -- 'v'
invalid or unknown argument
$ sudo LD_LIBRARY_PATH=lib64/ bin/cpupower monitor -V
monitor: invalid option -- 'V'

As the driver supports more devices over time the single MODULE_ALIAS

ASoC: fsl-asoc-card: set priv->pdev before using it
priv->pdev pointer was set after being used in
fsl_asoc_card_audmux_init().
Move this assignment at the start of the probe function, so
sub-functions can correctly use pdev through priv.

fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
dev struct, used with dev_err macros.
As priv is zero-initialised, there would be a NULL pointer dereference.
Note that if priv->dev is dereferenced before assignment but never used,
for example if there is no error to be printed, the driver won't crash
probably due to compiler optimisations.

ab069ce125 mmc: sdhci: Do not lock spinlock around mmc_gpio_get_ro()
sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.

However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().

So remove the locking.

fbd64f902b mmc: sdhci: Do not invert write-protect twice
mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.

sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.

Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".

Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.

Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.

Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

5a1906a476 gfs2: Revert "check for no eligible quota changes"
Since the previous commit, function gfs2_quota_sync() will not cause the
sync generation to creep forward by one every time the function is
called; this helps keep things a but more tidy.  We also don't care that
this function allocates a page of memory every time it is called, so no
good reason for keeping qd_changed() anymore, which just duplicates
qd_grab_sync().

This reverts commit 06aa6fd31a.

d9a75a6069 gfs2: Be more careful with the quota sync generation
The quota sync generation is only ever updated under sd_quota_sync_mutex
by gfs2_quota_sync(), but its current value is fetched ouside of that
mutex, so use WRITE_ONCE() and READ_ONCE() when accessing it without
holding that mutex.

Pass the current sync generation to do_sync() from its callers to ensure
that we're not recording the wrong generation when the syncing is
done.  Also, make sure that qd->qd_sync_gen only ever moves forward.

In gfs2_quota_sync(), only write the new sync generation when we know
that there are changes.  This eliminates the need for function
sd_changed(), which we will remove in the next commit.
