Here's a few stragglers. The first patch was submitted already but had
some bugs with unrecoverable exceptions on HPT (current->blah being
accessed before MSR[RI] was enabled). Those should be fixed now.

The others are generally for helping asynch interrupts, which are a bit
harder to measure well but important for IO and IPIs.

Applied to powerpc/next.
