Subject[GIT PULL] KVM fixes for Linux 5.16-rc5
Date
Linus,

The following changes since commit 0fcfb00b28c0b7884635dacf38e46d60bf3d4eb1:

Linux 5.16-rc4 (2021-12-05 14:08:22 -0800)

selftests: KVM: Add test to verify KVM doesn't explode on "bad" I/O (2021-12-10 09:38:02 -0500)

----------------------------------------------------------------
More x86 fixes:
* Logic bugs in CR0 writes and Hyper-V hypercalls
* Don't use Enlightened MSR Bitmap for L3
* Remove user-triggerable WARN

Plus a few selftest fixes and a regression test for the
user-triggerable WARN.

----------------------------------------------------------------
So I am not sure if this counts as "the kvm side calming down"; but the
larger scale bugfixes are all in-tree now, and what I've got here looks
(at least on the arch/ side) like a fairly normal pull request for
middle RCs.

Thanks,

Paolo
