[git pull] PCI code for 2.6.27-rc1

[git pull] PCI code for 2.6.27-rc1

[Jesse Barnes]

Please pull my for-linus branch:
git pull git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6.git for-linus

It contains quite a few fixes and changes I'd like to get into 2.6.27-rc1,
including several changes from the x86 forest.  See below for the shortlog
& diffstat.

Thanks,
Jesse

Were these patches posted to linux-pci?  I don't think I ever saw them.

No, but they're not really PCI specific patches.  They did go to lkml several 
times and have been sitting in one of Ingo's test trees for awhile.  There 
are no outstanding complaints that I'm aware of.
