PCI changes

Note! There are two branches available, see below.

The following changes since commit

Merge branch 'gpio/merge' of git://git.secretlab.ca/git/linux-2.6 (2011-10-14 17:07:52 +1200)

are available in the git repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci next-revert

Probably the most exciting bits of this series are the MPS fixes and Joerg's PASID stuff. But I don't think there's anything really risky (i.e. no big resource management changes this time around).

We found a problem on PPC with the latency setup changes, so this branch includes reverts for those patches. However, another branch is available with those patches rebased out if you prefer a cleaner changelog. See below for the changelog and diffstat to expect from that branch.

Ben Hutchings (2):

Thanks,

Hi,

Any chance to push https://lkml.org/lkml/2011/10/21/192 any time soon?

It pretty much is a necessary fix for a problem with _OSC after some recent changes.

Thanks,
Rafael

Yeah, pushed to my for-linus branch, thanks Rafael.
