Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] `include/kvm/arm_pmu.h` is no longer self-contained because it relies on `has_vhe()` without including `<asm/virt.h>`.

KVM: arm64: Reorganize PMU includes

This commit reorganizes the PMU includes to resolve a circular dependency
between asm/kvm_host.h and asm/arm_pmuv3.h. It removes the inclusion of
kvm_host.h from arm_pmuv3.h and moves the remaining KVM/PMU interfaces into
arm_pmu.h.

This isn't a bug, but by converting kvm_pmu_counter_deferred() from a static
inline function to a macro, do we lose type checking on the attr argument?

Additionally, this macro relies on has_vhe(), but asm/virt.h is not included
in this header. Does this leave the header no longer self-contained, relying
on callers to include asm/virt.h before using this macro?
