Pull powerpc fixes from Ben Herrenschmidt:
"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"
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc/pseries: Do not start secondaries in Open Firmware
powerpc/zImage: make the "OF" wrapper support ePAPR boot
powerpc: Remove ksp_limit on ppc64
powerpc/irq: Run softirqs off the top of the irq stack
