looks much better and the (minimal) generic impact is OK i think - as
long as Paul Acks the powerpc changes we could freeze that branch (so
that Paul can pull it in a few weeks) and base your ftrace-powerpc
work on that.

( The branch should still be named something constructive like
powerpc-ftrace-v29 or so - not ppc/ftrace-disable - but that's a
detail. )
