Argh, I haven't checked perf builds in a long time.  And yes, they are
broken.  Let me go fix these up for 6.18 and 7.1 and then drop all the
perf patches for older kernels as systems should always be using the
newest perf tool, not the older one, anyway.

I'll do that and then push out some -rc2 releases...
