[PATCH v4 1/4] KVM: arm64: Include kvm_mmu.h from vgic.h

[Gavin Shan]

We need a unified helper in 'kvm/vgic/vgic.h' to write guest memory. In
the helper, the check of no-running-vcpu context for dirty ring will be
applied. kvm_write_guest_lock(), defined in 'include/asm/kvm_mmu.h', is
going to be dereferenced by the unified helper.

Include 'include/asm/kvm_mmu.h' to 'kvm/vgic/vgic.h' to avoid including
the former header file when the later one is needed. With the change,
the duplicate inclusions of 'include/asm/kvm_mmu.h' are removed.

No functional change intended.
