[ Upstream commit 720e5c03e5cb26d33d97f55192b791bb48478aa5 ]
It is expected that the returned counters by .get_survey are monotonic
increasing. But the data from ath10k gets reset to zero regularly. Channel
active/busy time are then showing incorrect values (less than previous or
sometimes zero) for the currently active channel during successive survey
dump commands.
example:
$ iw dev wlan0 survey dump
Survey data from wlan0
frequency: 5180 MHz [in use]
channel active time: 54995 ms
channel busy time: 432 ms
channel receive time: 0 ms
channel transmit time: 59 ms
...
$ iw dev wlan0 survey dump
Survey data from wlan0
frequency: 5180 MHz [in use]
channel active time: 32592 ms
channel busy time: 254 ms
channel receive time: 0 ms
channel transmit time: 0 ms
...
The correct way to handle this is to use the non-clearing
WMI_BSS_SURVEY_REQ_TYPE_READ wmi_bss_survey_req_type. The firmware will
then accumulate the survey data and handle wrap arounds.

There are some updates for the Icelake model specific uncore performance
monitors. (The update can be found at 10th generation intel core
processors families specification update Revision 004, ICL068)
1) Counter 0 of ARB uncore unit is not available for software use
2) The global 'enable bit' (bit 29) and 'freeze bit' (bit 31) of
MSR_UNC_PERF_GLOBAL_CTRL cannot be used to control counter behavior.
Needs to use local enable in event select MSR.
Accessing the modified bit/registers will be ignored by HW. Users may
observe inaccurate results with the current code.
The changes of the MSR_UNC_PERF_GLOBAL_CTRL imply that groups cannot be
read atomically anymore. Although the error of the result for a group
becomes a bit bigger, it still far lower than not using a group. The
group support is still kept. Only Remove the *_box() related
implementation.
Since the counter 0 of ARB uncore unit is not available, update the MSR
address for the ARB uncore unit.
There is no change for IMC uncore unit, which only include free-running
counters.

We've met problems that occasionally tasks with full cpumask
(e.g. by putting it into a cpuset or setting to full affinity)
were migrated to our isolated cpus in production environment.
After some analysis, we found that it is due to the current
select_idle_smt() not considering the sched_domain mask.
Steps to reproduce on my 31-CPU hyperthreads machine:
1. with boot parameter: "isolcpus=domain,2-31"
(thread lists: 0,16 and 1,17)
2. cgcreate -g cpu:test; cgexec -g cpu:test "test_threads"
3. some threads will be migrated to the isolated cpu16~17.
Fix it by checking the valid domain mask in select_idle_smt().

In tx2_uncore_pmu_init_dev(), a call to acpi_dev_get_resources() is used
to create a list _CRS resources which is searched for the device base
address. There is an error check following this:
if (!rentry->res)
return NULL
In no case, will rentry->res be NULL, so the test is useless. Even
if the test worked, it comes before the resource list memory is
freed. None of this really matters as long as the ACPI table has
the memory resource. Let's clean it up so that it makes sense and
will give a meaningful error should firmware leave out the memory
resource.

This is due to use of an uninitialized local resource struct in the xgene
pmu driver. The thunderx2_pmu driver avoids this by using the resource list
constructed by acpi_dev_get_resources() rather than using a callback from
that function. The callback in the xgene driver didn't fully initialize
the resource. So get rid of the callback and search the resource list as
done by thunderx2.

Commit
0c2a3913d6f5 ("x86/fpu: Parse clearcpuid= as early XSAVE argument")
changed clearcpuid parsing from __setup() to cmdline_find_option().
While the __setup() function would have been called for each clearcpuid=
parameter on the command line, cmdline_find_option() will only return
the last one, so the change effectively made it impossible to disable
more than one bit.
Allow a comma-separated list of bit numbers as the argument for
clearcpuid to allow multiple bits to be disabled again. Log the bits
being disabled for informational purposes.
Also fix the check on the return value of cmdline_find_option(). It
returns -1 when the option is not found, so testing as a boolean is
incorrect.
