[PATCH v2 0/3] cpufreq: intel_pstate: Handle _PPC updates on global turbo disable/enable

Hi All,

This is a follow-up to the RFT patch set posted previously:
https://lore.kernel.org/lkml/9956076.F4luUDm1Dq@xxxxxxxxxxxxxx/

Patch [1/3] causes intel_pstate to update all policies if it gets a _PPC change
notification and sees a global turbo disable/enable change.

Patch [2/3] adds cpufreq_cpu_acquire() and cpufreq_cpu_release() to reduce
code duplication after the next patch a bit (and Srinivas wanted the rwsem
manipulation to not be done directly by the driver).

Patch [3/3] makes intel_pstate update cpuinfo.max_freq for all policies in
those cases.

I've atted Tested-by tags to patches [1/3] and [3/3], because there are only
cosmetic differences between them and what has been tested.

Thanks,
Rafael
