Sorry about the mixup, my bad v1 is the one you need for linux-3.1-rc1. > v2 didn't apply to linux-3.1-rc1 cleanly, but I think I got it right. v2 should apply cleanly ontop of linus/master as off: 1d229d5 Merge branch 'perf-urgent-for-linus' Because of the other patch already submitted by Linus. The result of the two patches should give you the same exact Kconfig file. Just applied on two different tips. Again sorry! Boaz > Maybe not.
