There have been little PowerPC changes in this cycle and I agree
with you on that it's a nice feature to have with little risk of

In fact, I also have an up-to-date (and hopefully working)
irqtrace/lockdep patch for 32-bit powerpc (we only do 64-bit right now)
that I'm considering merging this time around, the benefit it brings is
worth the risk I believe.
