Added custom channel-specific (temp1) attribute for resolution. The wait
time for a conversion in one-shot mode (enable = 0) depends on the
resolution.
When resolution is 12-bit, the conversion time is 140ms, but the minimum
update_interval is 125ms. Handled this problem by waiting an additional
15ms (125ms + 15ms = 140ms).
Added 'mask' parameter to the shutdown_write() function. Now it can
either write or update bits, depending on the value of mask. This is
needed, because for alarms a write is necessary, but for resolution only
the resolution bits should be updated.

Currently, i8k_dmi_table contains both entries used for DMI
matching and entries used to override config options. This
does not allow for differentiating between "its safe to issue
raw SMM calls on this machine" and "its not safe to issue raw
SMM calls on this machine, but here are some config values".
Since future SMM backends will need to differentiate between
those two cases, move those config entries into a separate
table. i8k_dmi_table now serves as a general "its safe to issue
raw SMM calls" table.

The EliteDesk 800 G6 stores a raw WMI string within the ACPI object in its
BIOS corresponding to one instance of HPBIOS_PlatformEvents.Name. This is
evidently a valid way of representing a WMI data item as far as the
Microsoft ACPI-WMI mapper is concerned, but is preventing the driver from
loading.
This seems quite rare, but add support for such strings. Treating this as a
quirk pretty much means adding that support anyway.
Also clean up an oversight in update_numeric_sensor_from_wobj() in which
the result of hp_wmi_strdup() was being used without error checking.

Based on the documentation below, the maximum number of Fan tach
channels is 16:
Documentation/devicetree/bindings/hwmon/aspeed-pwm-tacho.txt:45:
45 - aspeed,fan-tach-ch : should specify the Fan tach input channel.
46 integer value in the range 0 through 15, with 0 indicating
47 Fan tach channel 0 and 15 indicating Fan tach channel 15.
48 At least one Fan tach input channel is required.
However, the compiler doesn't know that, and legitimaly warns about a potential
overwrite in array `u8 fan_tach_ch_source[16]` in `struct aspeed_pwm_tacho_data`,
in case `index` takes a value outside the boundaries of the array:
drivers/hwmon/aspeed-pwm-tacho.c:
179 struct aspeed_pwm_tacho_data {
...
184 bool fan_tach_present[16];
...

Fix this by sanity checking `index` before using it to index arrays of
size 16 elements in `struct aspeed_pwm_tacho_data`. Also, pass `dev` as
argument to function `aspeed_create_fan_tach_channel()`, and add an error

- Add a forgotten CPU vendor check in the AMD microcode post-loading

x86/CPU/AMD: Check vendor in the AMD microcode callback
x86/sev: Fix kernel crash due to late update to read-only ghcb_version
* Set .owner for various KVM file_operations so that files refcount the
KVM module until KVM is done executing _all_ code, including the last
few instructions of kvm_put_kvm(). And then revert the misguided
attempt to rely on "struct kvm" refcounts to pin KVM-the-module.
ARM:
* Do not redo the mapping of vLPIs, if they have already been mapped
s390:
* Do not leave bits behind in PTEs
* Properly catch page invalidations that affect the prefix of a nested
guest
x86:
* When checking if a _running_ vCPU is "in-kernel", i.e. running at CPL0,
get the CPL directly instead of relying on preempted_in_kernel (which
is valid if and only if the vCPU was preempted, i.e. NOT running).
* Fix a benign "return void" that was recently introduced.
Selftests:
* Makefile tweak for dependency generation
* -Wformat fix
