The DRM layer keeps track of our vblanks and it assumes our vblank
counters only go back to zero when they overflow. The problem is that
when we disable the power well our counters also go to zero, but it
doesn't mean they did overflow. So on this patch we grab the lock and
update last_vblank so the DRM layer won't think our counters
overflowed.
This patch fixes the following intel-gpu-tools test:
./kms_flip --run-subtest blocking-absolute-wf_vblank

Apparently Bspec is wrong in this case here even for gm45. Note that
Bspec is horribly misguided on i965g/gm, so we don't have any other
data points besides that it seems to make machines work better.
With this changes all the bits in PORT_HOTPLUG_STAT for the digital
ports are ordered the same way. This seems to agree with what register
dumps from the hpd storm handling code shows, where the LIVE bit and
the short/long pulse STATUS bits light up at the same time with this
enumeration (but no with the one from Bspec).
Also tested on my gm45 which has two DP+ ports, and everything seems
to still work as expected.

a regression causing user-space-driven hibernation using the ioctl()

try_to_freeze(). Fix from Colin Cross addresses this by adding a
process flag to mark the hibernate/suspend process to inform the
freezer that that process should be ignored.

The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able
to dynamically set up MBus address decoding windows for PCI I/O and
memory regions depending on the PCI devices enumerated by Linux.
However, this emulated PCI-to-PCI bridge logic makes the Linux PCI
core believe that prefetchable memory regions are supported (because
the registers are read/write), while in fact no adress decoding window
is ever created for such regions. Since the Marvell MBus address
decoding windows do not distinguish memory regions and prefetchable
memory regions, this patch takes a simple approach: change the
PCI-to-PCI bridge emulation to let the Linux PCI core know that we
don't support prefetchable memory regions.
To achieve this, we simply make the prefetchable memory base a
read-only register that always returns 0. Reading/writing all the
other prefetchable memory related registers has no effect.
This problem was originally reported by Finn Hoffmann
<finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working
on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem
was that the PCI-to-PCI bridge emulation was making the Linux PCI core
believe that we support prefetchable memory, so the Linux PCI core was
only filling the prefetchable memory base and limit registers, which
does not lead to a MBus window being created. The below patch has been
confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has
otherwise been successfully tested on the Armada XP GP platform with a
e1000e PCIe NIC and a Marvell SATA PCIe card.

slots-fan on G5 Xserve is always running at full speed with windfarm_rm31
driver, resulting in a very high acoustic noise level. It seems the fan
parameters are incorrect, and have been copied from the Drive Bay fan
(RPM, not present on rm31) of the legacy therm_pm72 driver. This patch
changes the parameters to match the Slots fan (PWM) of therm_pm72. With
the patch, slots-fan speed drops from 99% to 19% during normal use,
and slots-temp settle to ~42'C.

Pull drm fixes from Dave Airlie:
"Radeon, nouveau, exynos, intel, mgag200..
Not all strictly regressions but there was probably only one patch I'd
have really left out and it didn't seem worth respinning exynos to
avoid it, the line change count is quite low.
radeon: regressions + more dynamic powermanagement fixes, since DPM
is a new feature, and off by default I'd prefer to keep merging
fixes since it has a large userbase already and I'd like to keep
them on mainline
nouveau: is mostly regression fixes
i915: is a regression fix since Daniel is on holidays I've merged it.
mgag200: I've picked a bunch of targetted fixes from a big bunch of
distro patches,
exynos: build fixes mostly, one regression fix
I expect things will slow right down now, I may send on the intel
early quirk from Jesse separatly, since I think the x86 maintainers
acked it"

Self explanitory dma_mapping_error addition to the 8139 driver, based on this:
https://bugzilla.redhat.com/show_bug.cgi?id=947250
It showed several backtraces arising for dma_map_* usage without checking the
return code on the mapping. Add the check and abort the rx/tx operation if its
failed. Untested as I have no hardware and the reporter has wandered off, but
seems pretty straightforward.

We can't use dev->mod_index for selecting the interrupt routing entry,
because it's not an index into interrupt routing table. It will be even
wrong on a machine with 2 CPUs (4 cores). But all needed information is
contained in the PAT entries for the serial ports. mod[0] contains the
iosapic address and mod_info has some indications for the interrupt
input (at least it looks like it). This patch implements the searching
for the right iosapic and uses this interrupt input information.

Allow binding of user memory to the AGP GART on systems with HP
Quicksilver AGP bus. This resolves 'bind memory failed' error seen in
dmesg:
[29.365973] [TTM] AGP Bind memory failed.
…
[29.367030] [drm] Forcing AGP to PCI mode
The system doesn't more fail to bind the memory, and hence not falling
back to the PCI mode (if other failures aren't detected).
This is just a simple write down from the following patches:
agp/amd-k7: Allow binding user memory to the AGP GART
agp/hp-agp: Allow binding user memory to the AGP GART
