[GIT PULL] KVM leftovers for 4.8-rc1

this pull request is a combination of two pull requests for 4.7-rc8 that
were not merged due to looking hairy. I have changed the tag message to
focus on circumstances of contained reverts as they were likely the
reason behind rejection.

First batch of 4.8-rc1 patches from kvm/next is coming later this week.

The following changes since commit a99cde438de0c4c0cecc1d1af1a55a75b10bfdef:

Linux 4.7-rc6 (2016-07-03 23:01:00 -0700)

arm64: KVM: VHE: Context switch MDSCR_EL1 (2016-07-23 18:07:12 +0200)

This merge introduces three patches that are later reverted,

- Switching of MSR_TSC_AUX in SVM was thought to cause a host
misbehavior, but it was later cleared of those doubts and the patch
moved code to a hot path, so we reverted it. That patch also needed
a fix for 32 bit builds and both were reverted in one go.

- Al Viro noticed that a fix for a leak in an error path was not valid
with the given API and provided a better fix, so the original patch
was reverted.

Then there are two VMX fixes that move code around because VMCS was not
accessed between vcpu_load() and vcpu_put(), a simple ARM VHE fix, and
two one-liners for PML and MTRR.

KVM: don't use anon_inode_getfd() before possible failures
