OK...  is perf/core (all 32 commits) headed into 3.7?  Because the perf
build is broken in 3.7-rcX, and we're at the point where Linus gets kind
of picky about what he accepts.  So we'd need your branch and David's to
fix compile issues.  And then we'd need Xiao Guangrong's fixes for 'perf
kvm' to only build on x86.  That's quite a number of fixes we need just
to get perf to compile.  Is someone other than me keeping track of

I would just like people to stop wondering when perf builds on non-x86
architectures will work.
