KVM: ARM/arm64: fix broken __percpu annotation (4000be42) · Commits · e / devices / android_kernel_oneplus_sm7250

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.
