Seems the crtc helpers call drm_calc_timestamping_constants()
unconditionally even if the driver didn't initialize vblank support by
calling drm_vblank_init(). That used to be OK since the constants were
stored under drm_crtc.

However I broke this with
commit eba1f35d ("drm: Move timestamping constants into drm_vblank_crtc")
when I moved the constants to live inside the drm_vblank_crtc struct
instead. If drm_vblank_init() isn't called, we don't allocate these
structures, and so drm_calc_timestamping_constants() will oops.

Fix it by adding a check into drm_calc_timestamping_constants() to see
if vblank support was initialized at all. And to keep in line with other
such checks, also toss in a check and warn for the case where vblank
support was initialized, but the wrong number of crtcs was specified.

Fixes the following sort of oops:

   - x86: support for Skylake per-guest TSC rate.  Long supported by
     AMD, the patches mostly move things from there to common
     arch/x86/kvm/ code.

   - generic: remove local_irq_save/restore from the guest entry and
     exit paths when context tracking is enabled.  The patches are a few
     months old, but we discussed them again at kernel summit.  Andy

Pull more power management and ACPI updates from Rafael Wysocki:
 "The only new feature in this batch is support for the ACPI _CCA device
  configuration object, which it a pre-requisite for future ACPI PCI
  support on ARM64, but should not affect the other architectures.

  The rest is fixes and cleanups, mostly in cpufreq (including
  intel_pstate), the Operating Performace Points (OPP) framework and
  tools (cpupower and turbostat).

  Specifics:

   - Support for the ACPI _CCA configuration object intended to tell the
     OS whether or not a bus master device supports hardware managed
     cache coherency and a new set of functions to allow drivers to
     check the cache coherency support for devices in a platform
     firmware interface agnostic way (Suravee Suthikulpanit, Jeremy
     Linton).

   - ACPI backlight quirks for ESPRIMO Mobile M9410 and Dell XPS L421X
     (Aaron Lu, Hans de Goede).

   - Fixes for the arm_big_little and s5pv210-cpufreq cpufreq drivers
     (Jon Medhurst, Nicolas Pitre).

   - kfree()-related fixup for the recently introduced CPPC cpufreq
     frontend (Markus Elfring).

   - intel_pstate fix reducing kernel log noise on systems where
     P-states are managed by hardware (Prarit Bhargava).

   - intel_pstate maintainers information update (Srinivas Pandruvada).

   - cpufreq core optimization related to the handling of delayed work
     items used by governors (Viresh Kumar).

   - Locking fixes and cleanups of the Operating Performance Points
     (OPP) framework (Viresh Kumar).

We should always use linux/types.h instead of asm/types.h for
consistency, and Kbuild actually warns about it:

./usr/include/asm/kvm.h:35: include of <linux/types.h> is preferred over <asm/types.h>

This patch does as Kbuild asks us.

On a cross-toolchain without glibc support, libgcov may not be
available, and attempting to build an arm64 kernel with GCOV
enabled then results in a build error:

/home/arnd/cross-gcc/lib/gcc/aarch64-linux/5.2.1/../../../../aarch64-linux/bin/ld: cannot find -lgcov

We don't really want to link libgcov into the vdso anyway, so
this patch just disables GCOV in the vdso directory, just as
we do for most other architectures.

cpus_have_hwcap() is defined as a 'static' function an only used in
one place that is inside of an #ifdef, so we get a warning when
the only user is disabled:

arch/arm64/kernel/cpufeature.c:699:13: warning: 'cpus_have_hwcap' defined but not used [-Wunused-function]

This marks the function as __maybe_unused, so the compiler knows that
it can drop the function definition without warning about it.

This fixes CVE-2015-5327.  It affects kernels from 4.3-rc1 onwards.

Fix the X.509 time validation to use month number-1 when looking up the
number of days in that month.  Also put the month number validation before
doing the lookup so as not to risk overrunning the array.

This can be tested by doing the following:

cat <<EOF | openssl x509 -outform DER | keyctl padd asymmetric "" @s

"Paolo,

I have two fixes for HV KVM which I would like to have included in
v4.4-rc1.  The first one is a fix for a bug identified by Red Hat
which causes occasional guest crashes.  The second one fixes a bug
which causes host stalls and timeouts under certain circumstances when
the host is configured for static 2-way micro-threading mode."

Pull xfs updates from Dave Chinner:
 "There is nothing really major here - the only significant addition is
  the per-mount operation statistics infrastructure.  Otherwises there's

  Summary:

   - per-mount operational statistics in sysfs
   - fixes for concurrent aio append write submission
   - various logging fixes

  The remaining patches are minor fixes and cleanups across the board.

  Note that one of the patches included in this pull request is against
  arch/unicore32.  I've included it here because I couldn't get a
