Subject: [PATCH 1/2] RCU: Don't include unnecessary headers, allow kmemtrace w/ tracepoints.

linux/percpu.h includes linux/slab.h, which generates circular inclusion
dependencies when trying to switch kmemtrace to use tracepoints instead
of markers. This patch allows tracing within slab headers' inline
functions.
