Subject[PATCH 0/5] kvm: x86: better handling of NULL-able kvm_x86_ops
Date
This series is really two changes:

- patch 1 to 4 clean up NULLable kvm_x86_ops so that they are marked
in kvm-x86-ops.h and the non-NULLable ones WARN if used incorrectly.
As an additional outcome of the review, a few more uses of
static_call_cond are introduced.

- patch 5 allows to NULL a few kvm_x86_ops that return a value, by
using __static_call_ret0.

Paolo Bonzini (5):
KVM: x86: use static_call_cond for optional callbacks
KVM: x86: mark NULL-able kvm_x86_ops
KVM: x86: warn on incorrectly NULL static calls
KVM: x86: change hwapic_{irr,isr}_update to NULLable calls
KVM: x86: allow defining return-0 static calls
