The #1 problem child in this particular case, the one you should
care about most is:
perf record -e cycles:pp
As 99% of the people won't be doing any host or guest side
profiling, they just want to do profiling.
In older code (v3.6 and before) -e cycles:p sets the exclude_guest flag
to 0, so -e cycles:p and -e cycles:pG are equivalent with respect to
exclude_guest.
Ok? So now we need a patch that does all that - otherwise we'll
have to revert the one that added the regression.
I will not have time to work on a patch until Sunday at the earliest.
