Subject: KVM: ARM/arm64: fix broken __percpu annotation

From: Will Deacon <[email protected]>

commit 4000be423cb01a8d09de878bb8184511c49d4238 upstream.

Running sparse results in a bunch of noisy address space mismatches thanks to the broken __percpu annotation on kvm_get_running_vcpus.

This function returns a pcpu pointer to a pointer, not a pointer to a pcpu pointer. This patch fixes the annotation, which kills the warnings from sparse.
