[PATCH v4 0/2] x86/kvm: Reduce vcpu_is_preempted() overhead
v3->v4:
- Fix x86-32 build error.
v2->v3:
- Provide an optimized __raw_callee_save___kvm_vcpu_is_preempted()
in assembly as suggested by PeterZ.
- Add a new patch to change vcpu_is_preempted() argument type to long
to ease the writing of the assembly code.
v1->v2:
- Rerun the fio test on a different system on both bare-metal and a
KVM guest. Both sockets were
