Christophe Leroy cd99ddbea2 powerpc/8xx: Only perform perf counting when perf is in use. ... In TLB miss handlers, updating the perf counter is only useful when performing a perf analysis. As it has a noticeable overhead, let's only do it when needed. In order to do so, the exit of the miss handlers will be patched when starting/stopping 'perf': the first register restore instruction of each exit point will be replaced by a jump to the counting code. Once this is done, CONFIG_PPC_8xx_PERF_EVENT becomes useless as this feature doesn't add any overhead.
