The PCI linux-next branch was a bit more exciting than I expected it to be.
We've got lots of good changes queued up (patches may follow this mail if I
can get git send-email to cooperate).
Some of the highlights:
- PCI slot detection driver (from Alex Chiang)
This driver exposes additional per-slot information that can help
users identify where slots are physically located, making hotplug
easier to deal with.
- ROM allocation avoidance (Gary Hade)
With the "don't allocate space for ROMs" patch reverted, lots of
address space can be gobbled up by unnecessary expansion ROMs. To
prevent this on large systems, Gary added an option eschew ROM
allocation, so that machines not needing access to the ROMs can use
more of their address space for important MMIO and I/O regions
instead.
- PCIe hotplug cleanups/fixes (Kenji Kaneshige)
Kenji spent a lot of time working on improving the PCIe and other
hotplug drivers. Things should be more reliable and the code should
be easier to follow now thanks to his efforts.
- suspend/resume & wakeup enhancements (Rafael J. Wysocki)
Rafael coded up quite a few improvements to our suspend/resume
infrastructure, and fixed up PCI/ACPI wakeup while he was at it.
The improved wakeup code should work on more platforms and in more
situations than the old code, but we still expect additional platform
specific quirks and workarounds will be necessary, so testing in
this area is welcome. But everyone's already setting their systems
to go to sleep automatically though, for power savings & general
"green" goodness, right? These improvements should make things like
wake-on-lan a bit more reliable, so if you're not already in the
green camp, please give these bits a try.

There's also an assortment of fixes here; hopefully we haven't broken
anything too badly!

I wanted to see how badly upstream would conflict; turns out only trivially).
