Here are a few things for -rc2, this time it's all written by me so it can only be perfect .... right ? :) So we have the fix to call irq_enter/exit on the irq stack we've been discussing, plus a cleanup on top to remove an unused (and broken) stack limit tracking feature (well, make it 32-bit only in fact where it is used and works properly). Then we have two things that I wrote over the last couple of days and made the executive decision to include just because I can (and I'm sure you won't object .... right ?). They fix a couple of annoying and long standing "issues": - We had separate zImages for when booting via Open Firmware vs. booting via a flat device-tree, while it's trivial to make one that deals with both - We wasted a ton of cycles spinning secondary CPUs uselessly at boot instead of starting them when needed on pseries, thus contributing significantly to global warming. Cheers, Ben.
