Tejun Heo 43cf38eb5c percpu: add __percpu sparse annotations to core kernel subsystems
Add __percpu sparse annotations to core subsystems.

These annotations are to make sparse consider percpu variables to be
in a different address space and warn if accessed without going
through percpu accessors.  This patch doesn't affect normal builds.
