Subject: [patch 00/14] x86/irq: Plug various vector cleanup races

Joe reported a nasty race in the vector cleanup code which results in stale
irq descriptors in the vector arrays and a potential use after free.

This series addresses this issue, another race which was found and fixed by
Jiang related to the same area, plus a cpu hotplug issue which is not related
to this.

This lot is intended for stable, but not yet marked so. The diffstat below is
rather large, but this is mostly due to extensive commentry which I added in
the process.

This is also available via git from:

  git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/apic

Thanks,

	tglx
