[git pull] x86 fixes

[Ingo Molnar <mingo@elte.hu>]

Linus,

Please pull the latest x86-fixes-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git x86-fixes-for-linus

(the out-of-topic bits come from a half-revert of a bad commit that went 
upstream prematurely via the PCI tree - has the ack of Jesse as well.)

 out-of-topic modifications in x86-fixes-for-linus:
 --------------------------------------------------
 include/linux/iommu-helper.h     # 8978b74: generic, x86: fix add iommu_num_p
 init/calibrate.c                 # d7ba11d: x86: remove stray <6> in BogoMIPS
 lib/iommu-helper.c               # 8978b74: generic, x86: fix add iommu_num_p

Thanks,

	Ingo
