Subject: [GIT pull] smp hotplug cleanups for 3.5
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
