Subject[GIT PULL] Second batch of KVM changes for 4.4 (v2)
Date
Linus,

The following changes since commit a3eaa8649e4c6a6afdafaa04b9114fb230617bb1:

KVM: VMX: Fix commit which broke PML (2015-11-05 11:34:11 +0100)

are available in the git repository at:

git://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus

for you to fetch changes up to 370289756beccdc2a6ef9c7998fe67a7ca68bfc2:

Merge branch 'kvm-ppc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc into HEAD (2015-11-12 10:07:07 +0100)

I had previously sent this pull request (minus the PPC changes) on Nov 10th,
but forgot to include you explicitly in the recipients. So you actually
never got the v1.

----------------------------------------------------------------

Four changes:

- x86: work around two nasty cases where a benign exception occurs while
another is being delivered. The endless stream of exceptions causes an
infinite loop in the processor, which not even NMIs or SMIs can interrupt;
in the virt case, there is no possibility to exit to the host either.

- 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 will pick up
from here and, in 4.5, try to remove it from the user entry/exit paths.

- PPC: Two bug fixes, see merge commit 370289756becc for details.
