Fix a bug where MSHV root partitions don't honor NEED_RESCHED_LAZY, and then
deduplicate the TIF related MSHV code by turning the "kvm" entry APIs into
more generic "virt" APIs (which ideally would have been done when MSHV root
support was added).
Assuming all is well, maybe this could go through the tip tree?
The Hyper-V stuff and non-x86 architectures are compile-tested only.
Sean Christopherson (5):
Drivers: hv: Move TIF pre-guest work handling fully into mshv_common.c
Drivers: hv: Handle NEED_RESCHED_LAZY before transferring to guest
entry/kvm: KVM: Move KVM details related to signal/-EINTR into KVM
proper
entry: Rename "kvm" entry code assets to "virt" to genericize APIs
Drivers: hv: Use common "entry virt" APIs to do work before running
guest
