[PATCH v4 0/5] cpufreq: intel_pstate: Address some HWP-related oddities

[Rafael J. Wysocki]

Hi All,

The last two patches in the v3 needed to be updated to take re-enabling of HWP
after an ACPI S3 suspend/resume cycle into account appropriately.  The first
three patches are the same as before.

The purpose of this series is to address some peculiarities related to
taking CPUs offline/online and switching between different operation
modes with HWP enabled that have become visible after allowing the
driver to work in the passive mode with HWP enabled in 5.9-rc1 (and
one that was there earlier, but can be addressed easily after the
changes made in 5.9-rc1).

Please refer to the patch changelogs for details.

For easier testing/review, the series is available from the git branch at:

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 intel_pstate-testing

I've done my best to address all of the possible corner cases, but the test
matrix is quite extensive and I may have missed something, so go ahead
and test.

Thanks,
Rafael
