Subject: [PATCH v3 0/5] cpufreq: intel_pstate: Address some HWP-related oddities

Hi All,

The v3 is here to address feedback from Srinivas and Doug, and Artem concerns
regarding the EPP sysfs interface changes.

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
