[SPARC64]: Fix race in LOAD_PER_CPU_BASE() Since we use %g5 itself as a temporary, it can get clobbered if we take an interrupt mid-stream and thus cause end up with the final %g5 value too early as a result of rtrap processing. Set %g5 at the very end, atomically, to avoid this problem. Signed-off-by: David S. Miller <davem@davemloft.net>
