Applied to kvm-x86 next. Dapeng, I didn't address your feedback about adding
finer grained message prefixes. I'm not opposed to doing so, I'm just extremely
short on cycles and want to get the fixes landed.
[1/4] x86/pmu: Enable PEBS on fixed counters iff baseline PEBS is support
https://github.com/kvm-x86/kvm-unit-tests/commit/79aa106cd427
[2/4] x86/pmu: Iterate over adaptive PEBS flag combinations
https://github.com/kvm-x86/kvm-unit-tests/commit/fc17d5276b38
[3/4] x86/pmu: Test adaptive PEBS without any adaptive counters
https://github.com/kvm-x86/kvm-unit-tests/commit/2cb2af7f53db
[4/4] x86/pmu: Add a PEBS test to verify the host LBRs aren't leaked to the guest
