KVM: selftests: fix rdtsc() for vmx_tsc_adjust_test (2020-06-01 11:58:23 -0400)
----------------------------------------------------------------
ARM:
- Move the arch-specific code into arch/arm64/kvm
- Start the post-32bit cleanup
- Cherry-pick a few non-invasive pre-NV patches
x86:
- Rework of TLB flushing
- Rework of event injection, especially with respect to nested virtualization
- Nested AMD event injection facelift, building on the rework of generic code
and fixing a lot of corner cases
- Nested AMD live migration support
- Optimization for TSC deadline MSR writes and IPIs
- Various cleanups
- Asynchronous page fault cleanups (from tglx, common topic branch with tip tree)
- Interrupt-based delivery of asynchronous "page ready" events (host side)
- Hyper-V MSRs and hypercalls for guest debugging
- VMX preemption timer fixes
s390:
- Cleanups
Generic:
- switch vCPU thread wakeup from swait to rcuwait
The other architectures, and the guest side of the asynchronous page fault
work, will come next week.
