Cover letter [PATCH 0/9] KVM backports to 5.10
This patch series backports a few VM preemption_status, steal_time and PV TLB flushing fixes to 5.10 stable kernel.
Most of the changes backport cleanly except i had to work around a few becauseof missing support/APIs in 5.10 kernel. I have captured those in the changelog as well in the individual patches.
Changelog
- Use mark_page_dirty_in_slot api without kvm argument (KVM: x86: Fix recording of guest steal time / preempted status)
- Avoid checking for xen_msr and SEV-ES conditions (KVM: x86:
do not set st->preempted when going back to user space)
- Use VCPU_STAT macro to expose preemption_reported and preemption_other fields (KVM: x86: do not report a vCPU as preempted outside instruction boundaries)
