[PATCH 14/26] KVM: arm64: Move ARM specific headers in include/kvm to arch directory

Sean Christopherson
2023-09-16T00:33:25Z

Move kvm/arm_{arch_timer,pmu,vgic}.h to arch/arm64/include/asm and drop
the "arm" prefix from all file names. Now that KVM no longer supports
32-bit ARM, there is no reason to expose ARM specific headers to other
architectures beyond arm64.
