[git pull] PCI changes for 2.6.33
From: Jesse Barnes
Date: Fri Dec 11 2009 - 14:02:49 EST
The following changes since commit a8a8a669ea13d792296737505adc43ccacf3a648:
Linus Torvalds (1):
Merge branch 'i2c-pnx-fixes' of git://git.fluff.org/bjdooks/linux
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6 linux-next
I've got a section mismatch in here, but the fix will be part of the next
pull req (updated patch just came in recently).
Probably the biggest change here (at least my change count) is Bjorn's
MMCONFIG rework. It sets the stage for hot plugging of host bridges and
_CBA and includes some nice cleanups besides.
Aside from that we have the usual set of PCI hotplug changes (Kenji-san is
slowly making the PCIe hotplug and port driver code sane) and a bunch of
bug fixes (some too invasive to make 2.6.32 and some that just came in too
late).
There will be one more pull req. with a small feature addition to allow for
per-device PCI reset functionality, needed for some USB and virtual devices.
It's had review though (it's a fairly old patchset), just didn't make it into
linux-next in time for this pull request due to timing of comment feedback
and slowness on my part.
