[GIT PULL] Power management fixes for v4.12-rc5

[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.12-rc5

with top-most commit fbd78afe34d9cc3a86aff7cc214d9f06e815e63e

 Merge branches 'intel_pstate' and 'pm-sleep'

on top of commit 3c2993b8c6143d8a5793746a54eba8f86f95240f

 Linux 4.12-rc4

to receive power management fixes for v4.12-rc5.

These revert one problematic commit related to system sleep and fix
one recent intel_pstate regression.

Specifics:

 - Revert a recent commit that attempted to avoid spurious wakeups
   from suspend-to-idle via ACPI SCI, but introduced regressions on
   some systems (Rafael Wysocki).

   We will get back to the problem it tried to address in the next
   cycle.

 - Fix a possible division by 0 during intel_pstate initialization
   due to a missing check (Rafael Wysocki).

Thanks!
