On some platform(.e.g. i.MX8QM MEK), the "extal" clock is different
with the mclk of codec, then the clock rate is also different.
So it is better to get clock rate of "extal" rate by clk_get_rate,
don't reuse the clock rate of mclk.

Currently list of Qualcomm drivers is growing, so put them in to a

This allows solutions like ALSA UCM to utilize hardware mono downmix
for cases where mono output to a single speaker is desired only in

Use the new common snd_soc_of_parse_aux_devs() helper function
to parse auxiliary devices from the device tree. The new helper
is just a copy of meson_card_add_aux_devices() so there is no
functional change.

simple-card.c and meson-card-utils.c use pretty much the same
helper function to parse auxiliary devices from the device tree.
Make it easier for other drivers to parse these from the device tree
as well by adding a shared helper function to soc-core.c.
snd_soc_of_parse_aux_devs() is pretty much a copy of
meson_card_add_aux_devices() from meson-card-utils.c
with two minor changes:
- Make property name configurable as parameter
- Change dev_err() message slightly for consistency with other
error messages in soc-core.c

"AVDD" is for analog power supply, "DVDD" is for digital power
supply, they can improve the power management.
As the regulator is enabled in pm runtime resume, which is
behind the component driver probe, so accessing registers in
component driver probe will fail. Fix this issue by enabling
regcache_cache_only after pm_runtime_enable.

IA32_MCG_STATUS.RIPV indicates whether the return RIP value pushed onto
the stack as part of machine check delivery is valid or not.
Various drivers copied a code fragment that uses the RIPV bit to
determine the severity of the error as either HW_EVENT_ERR_UNCORRECTED
or HW_EVENT_ERR_FATAL, but this check is reversed (marking errors where
RIPV is set as "FATAL").
Reverse the tests so that the error is marked fatal when RIPV is not set.

I do not know when ConfigInfoView::createStandardContextMenu() is
called.
Because QTextEdit::createStandardContextMenu() is not virtual,
ConfigInfoView::createStandardContextMenu() cannot override it.
Even if right-click the ConfigInfoView window, the "Show Debug Info"
menu does not show up.
Build up the menu in the constructor, and invoke it from the
contextMenuEvent().

If you right-click in the ConfigList window, you will see the following
messages in the console:
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:888
QObject::connect: (sender name: 'config')
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:897
QObject::connect: (sender name: 'config')
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:906
QObject::connect: (sender name: 'config')
Right, there is no such slot in QAction. I think this is a typo of
setChecked.
Due to this bug, when you toggled the menu "Option->Show Name/Range/Data"
the state of the context menu was not previously updated. Fix this.

drain_pages
drain_pages_zone
free_pcppages_bulk
where drain_pages() in this case is called under the assumption that
the unplugged cpu is no longer executing. To ensure that is the case,
and early call is made to __cpu_die()->pseries_cpu_die(), which runs a
loop that waits for the cpu to reach a halted state by polling its
status via query-cpu-stopped-state RTAS calls. It only polls for 25
iterations before giving up, however, and in the trace above this
results in the following being printed only .1 seconds after the
hotplug worker thread begins processing the unplug request:
pseries-hotplug-cpu: Attempting to remove CPU <NULL>, drc index: 1000013a
Querying DEAD? cpu 314 (314) shows 2
At that point the worker thread assumes the unplugged CPU is in some
unknown/dead state and procedes with the cleanup, causing the race
with the XIVE cleanup code executed by the unplugged CPU.
Fix this by waiting indefinitely, but also making an effort to avoid
spurious lockup messages by allowing for rescheduling after polling
the CPU status and printing a warning if we wait for longer than 120s.

On BOOK3S_32, when we have modules and strict kernel RWX, modules
are not in vmalloc space but in a dedicated segment that is
below PAGE_OFFSET.
So KASAN_SHADOW_START must take it into account.
MODULES_VADDR can't be used because it is not defined yet
in kasan.h

is in the middle of reset. The reset path has deleted the association and
freed aen_op->fcp_req.private. Add a check for this private pointer before
