The kernel patches are in tip/perf/core now, so I applied the patches
and they seem to work, but they broke one 'perf test' entry:

# perf test 5
 5: parse events tests                                       : FAILED!

# perf test -v 5
<SNIP>
running test 50 '4:0x6530160/name=numpmu/'
running test 51 'L1-dcache-misses/name=cachepmu/'
running test 0 'cpu/config=10,config1,config2=3,period=1000/u'
running test 1 'cpu/config=1,name=krava/u,cpu/config=2/u'
running test 2 'cpu/config=1,call-graph=fp,time,period=100000/,cpu/config=2,call-graph=no,time=0,period=2000/'
Invalid sysfs entry event=topdown-recovery-bubbles.scale
failed to parse event 'cpu/event=topdown-recovery-bubbles.scale/u', err 1
test child finished with 1
---- end ----
parse events tests: FAILED!

Please check that,
