The vega10_odn_update_soc_table() function does not allow the SCLK
dependent voltage to be set for power-state 7 to a value below the default

	make[3]: *** No rule to make target '/linux-build/bpf/test_stub.o', needed by '/linux-build/bpf/test_verifier'

91636a8204 ALSA: hda: Allow non-Intel device probe gracefully
The recent addition of snd_intel_dsp_driver_probe() check caused a
spurious kernel warning when the driver is loaded for a non-Intel
hardware due to snd_BUG_ON().  Moreover, for such a hardware, we
should always return SND_INTEL_DSP_DRIVER_ANY, not check the
dsp_driver option at all.

This patch fixes these issues for non-Intel devices.

406857f773 ACPI: EC: add support for hardware-reduced systems
As defined in the ACPI spec section 12.11, ACPI hardware-reduced
platforms define the EC SCI interrupt as a GpioInt in the _CRS object.

This replaces the previous way of using a GPE for this interrupt;
GPE blocks are not available on reduced hardware platforms.

Add support for handling this interrupt as an EC event source, and
avoid GPE usage on reduced hardware platforms.

This enables the use of several media keys (e.g. screen brightness
up/down) on Asus UX434DA.

ASoC: SOF: ignore suspend/resume for D0ix compatible streams
During system suspend, the PM framework will freeze all applications and
the ALSA/ASoC core will suspend all RUNNING PCM streams.

However, D0ix-compatible PCM streams should keep the related pipelines
active in the DSP when the system is entering S0ix. The TRIGGER_SUSPEND
event is trapped in such cases to prevent the pipelines from being
stopped. Likewise, the TRIGGER_RESUME/START events should not affect the
pipeline state.

The SOF driver also triggers some DSP Firmware pipelines based on the
DAPM widgets power events. In such cases, we also ignore PRE_PMU and
POST_PMD events to keep the pipelines active.

D0i3 is a platform-defined substate of D0, so we need a

00e250367c ACPI: button: Add DMI quirk for Asus T200TA
The Asus T200TA lid has some weird behavior where _LID keeps reporting
closed after every second openening of the lid. Causing immediate
re-suspend after opening every other open.

I've looked at the AML code but it involves talking to the EC and we
have no idea what the EC is doing. Setting lid_init_state to
ACPI_BUTTON_LID_INIT_OPEN fixes the unwanted behavior, so this commit
adds a DMI based quirk to use ACPI_BUTTON_LID_INIT_OPEN on the T200TA.

932e1ba486 ACPI: button: Add DMI quirk for Medion Akoya E2215T
The Medion Akoya E2215T's ACPI _LID implementation is quite broken:

 1. For notifications it uses an ActiveLow Edge GpioInt, rather then
    an ActiveBoth one, meaning that the device is only notified when the
    lid is closed, not when it is opened.

2. Matching with this its _LID method simply always returns 0 (closed)

  In order for the Linux LID code to work properly with this implementation,
  the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN.

This commit adds a DMI quirk for this.

d7cd08231a ACPI: button: Turn lid_blacklst DMI table into a generic quirk table
Commit 3540c32a9a ("ACPI / button: Add quirks for initial lid state
notification") added 3 different modes to the LID handling code to deal
with various buggy implementations.

Until now users which need one of the 2 non-default modes to get their
HW to work have to pass a kernel commandline option for this.

E.g. https://bugzilla.kernel.org/show_bug.cgi?id=106151 was closed with a
note that the user has to add "button.lid_init_state=open" to the kernel
commandline to get the LID code to not cause undesirable suspends on his
Samsung N210 Plus.

This commit modifies the existing lid_blacklst DMI table so that it can
be used not only to completely disable the LID code on devices where
the ACPI tables are broken beyond repair, but also to select one of the 2
non default LID handling modes on devices where this is necessary.

This will allow us to add quirks to make the LID work OOTB on broken
devices. Getting this working OOTB is esp. important because the typical
breakage is false LID closed reporting, causing undesirable suspends which
basically make the system unusable.

593681e2c7 ACPI: button: Allow disabling LID support with the lid_init_state module option
Add a new "disabled" value for the lid_init_state module option, which can
be used to disable LID support on devices where it is completely broken.

Sometimes devices seem to spontaneously suspend and the cause for this is
not clear. The LID switch is known to be one possible cause for this,
this commit allows easily disabling the LID switch for testing if it
is the cause.

For example some devices which do not even have a lid, still have a LID
device in their ACPI tables, pointing to a floating GPIO.

This is not really related to the initial LID state, but re-using the
existing option keeps things simple and it will make it much easier to
add DMI quirks which can either disable the LID completely or set another
non-default lid_init_state value, both of which are necessary on some
devices.

065bd4d35b ACPI: button: Refactor lid_init_state module parsing code
Replace the weird strncmp() calls in param_set_lid_init_state(),
which look to me like they will also accept things like "opennnn"
to use sysfs_match_string instead.

Also rewrite param_get_lid_init_state() using the new lid_init_state_str
array. Instead of doing a straightforward one line replacement, e.g. :
  return sprintf(buffer, lid_init_state_str[lid_init_state]);
print all possible values, putting [] around the selected value, so
that users can easily find out what the possible values are.

dd7dafd1ad rcu: Make kernel-mode nohz_full CPUs invoke the RCU core processing
If a nohz_full CPU is idle or executing in userspace, it makes good sense
to keep it out of RCU core processing.  After all, the RCU grace-period
kthread can see its quiescent states and all of its callbacks are
offloaded, so there is nothing for RCU core processing to do.

However, if a nohz_full CPU is executing in kernel space, the RCU
grace-period kthread cannot do anything for it, so such a CPU must report
its own quiescent states.  This commit therefore makes nohz_full CPUs
skip RCU core processing only if the scheduler-clock interrupt caught
them in idle or in userspace.
