Subject: [GIT PULL] ACPI CPPC fixes for v4.10-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-urgent-4.10-rc1

with top-most commit cc31e9b718dafd8a1bdc593234ddbbf4faa2511c

 Merge branch 'acpi-cppc'

on top of commit a67485d4bf97918225dfb5246e531643755a7ee1

 Merge tag 'acpi-4.10-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive two ACPI CPPC fixes for v4.10-rc1.

One of them fixes a crash in KVM encountered by Sebastian in
linux-next and introduced by a recent intel_pstate change that
caused the driver to use the ACPI CPPC code and uncovered a
missing NULL pointer check in it.

The other one fixes a possible use-after-free in the same code
area.

Thanks!
