powerpc/e6500: hw tablewalk: optimize a bit for tcd lock acquiring codes It makes no sense to put the instructions for calculating the lock value (cpu number + 1) and the clearing of eq bit of cr1 in lbarx/stbcx loop. And when the lock is acquired by the other thread, the current lock value has no chance to equal with the lock value used by current cpu. So we can skip the comparing for these two lock values in the lbz/bne loop. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
