Linus,
Please pull the latest x86-cpu-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cpu-for-linus
# HEAD: 283bab9809786cf41798512f5c1e97f4b679ba96 x86/cpu: Remove redundant cpu_detect_cache_sizes() call
The biggest change in this cycle was a large series from Sean
Christopherson to clean up the handling of VMX features. This both fixes
bugs/inconsistencies and makes the code more coherent and future-proof.
There are also two cleanups and a minor TSX syslog messages enhancement.
Thanks,
Ingo
------------------>
Borislav Petkov (2):
x86/bugs: Move enum taa_mitigations to bugs.c

x86/cpu: Set synthetic VMX cpufeatures during init_ia32_feat_ctl()
x86/cpufeatures: Add flag to track whether MSR IA32_FEAT_CTL is configured
KVM: VMX: Drop initialization of IA32_FEAT_CTL MSR
KVM: VMX: Use VMX feature flag to query BIOS enabling
KVM: VMX: Check for full VMX support when verifying CPU compatibility

No diffstat in the pull request?
The shortlog does match, and the diffstat I get looks sane, so I'm
pulling it, but please fix whatever thing that caused the diffstat to
not show in the email..

My bad: I erased the patch part manually and went too far accidentally. :-/
