Vineet Gupta 1097163870 ARCv2: spinlock/rwlock/atomics: reduce 1 instruction in exponential backoff ... The increment of delay counter was 2 instructions: Arithmatic Shfit Left (ASL) + set to 1 on overflow This can be done in 1 using ROtate Left (ROL) Suggested-by: Nigel Topham <ntopham@synopsys.com> Cc: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: linux-kernel@vger.kernel.org Signed-off-by: Vineet Gupta <vgupta@synopsys.com>		2015-08-07 13:56:16 +05:30
