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
