From 60731b1c244efd3192f1fb36c843a0a3add66599 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 26 Aug 2014 15:13:21 +0100 Subject: [PATCH] KVM: ARM/arm64: fix broken __percpu annotation 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.
