Apologies, I'm being a moron today.
That won't apply cleanly due to minor changes in arch-x86.h, but easy
to apply by hand. Also the type of ioprio_set() has changed, but
Android was not updated.
So, attached is a patch that should get tip back to the state where I
thought it was -- weird asm errors.
Sorry for the confusion.
