Linus,

please pull the latest smp-hotplug-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git smp-hotplug-for-linus

This series is merily a cleanup of code copied around in arch/* and
not changing any of the real cpu hotplug horrors yet. I wish I'd had
something more substantial for 3.5, but I underestimated the lurking
horror....

Changelog and diffstat below, but full patch omitted due to size
reasons.

Thanks,

tglx
