- Make the logic in r100_pll_errata_after_index() match the other
errata functions
- Use rdev->family rather than rdev->flags & RADEON_FAMILY_MASK for kms

92897b5c66 drm: add "auto" dithering method
There's no convenient/reliable way for drivers to both obey the dithering
mode property, and to be able to attempt to provide a good default in all
cases.

This commit adds an "auto" method to the property which drivers can default
to if they wish, whilst still allowing the user to override the choice as
they do now.

023eb571a1 drm: correctly update connector DPMS status in drm_fb_helper
We don't currently update the DPMS status of the connector (both in the
connector itself and the connector's DPMS property) in the fb helper
code.  This means that if the kernel FB core has blanked the screen,
sysfs will still show a DPMS status of "on".  It also means that when X
starts, it will try to light up the connectors, but the drm_crtc_helper
code will ignore the DPMS change since according to the connector, the
DPMS status is already on.

Fixes https://bugs.freedesktop.org/show_bug.cgi?id=28436 (the annoying
"my screen was blanked when I started X and now it won't light up" bug).

709ea97145 drm: implement helper functions for scanning lru list
These helper functions can be used to efficiently scan lru list
for eviction. Eviction becomes a three stage process:
1. Scanning through the lru list until a suitable hole has been found.
2. Scan backwards to restore drm_mm consistency and find out which
   objects fall into the hole.
3. Evict the objects that fall into the hole.

These helper functions don't allocate any memory (at the price of
not allowing any other concurrent operations). Hence this can also be
used for ttm (which does lru scanning under a spinlock).

Evicting objects in this fashion should be more fair than the current
approach by i915 (scan the lru for a object large enough to contain
the new object). It's also more efficient than the current approach used
by ttm (uncoditionally evict objects from the lru until there's enough
free space).

5870a4d97d drm/ttm: Allocate the page pool manager in the heap.
Repeated ttm_page_alloc_init/fini fails noisily because the pool
manager kobj isn't zeroed out between uses (we could do just that but
statically allocated kobjects are generally considered a bad thing).
Move it to kzalloc'ed memory.

Note that this patch drops the refcounting behavior of the pool
allocator init/fini functions: it would have led to a race condition
in its current form, and anyway it was never exploited.

This fixes a regression with reloading kms modules at runtime, since
page allocator was introduced.

2d95d8158b i7core_edac: Avoid doing multiple probes for the same card
As Nehalem/Nehalem-EP/Westmere devices uses several devices for the same
functionality (memory controller), the default way of proping devices doesn't
work. So, instead of a per-device probe, all devices should be probed at once.

This means that we should block any new attempt of probe, otherwise, it will
try to register the same device several times.

bda142890e i7core_edac: Properly discover the first QPI device
On Nehalem/Nehalem-EP/Westmere, the first QPI device is the last PCI bus.
The last bus is generally at 0x3f or 0xff, but there are also other systems
using different setups. For example, HP Z800 has 0x7f as the last bus.

This patch adds a logic to discover the last bus, dynamically detecting it
at runtime.

When calculating the DCT channel from the syndrome we need to know the

cfg space register F3x180 while on K8 we only support x4 syndromes and
don't have extended PCI config space anyway.

Make the code accessing F3x180 F10h only and fall back to x4 syndromes
on everything else.

980533b018 correct console log level when ERST ACPI table is not found
When booting 2.6.35-rc3 on a x86 system without an ERST ACPI table with
the 'quiet' option, we still observe an "ERST: Table is not found!"
warning.

Quiesce it to the same info log level as the other 'table not found'
warnings.

985b823b91 drm/i915: fix hibernation since i915 self-reclaim fixes
Since commit 4bdadb9785 ("drm/i915:
Selectively enable self-reclaim"), we've been passing GFP_MOVABLE to the
i915 page allocator where we weren't before due to some over-eager
removal of the page mapping gfp_flags games the code used to play.

This caused hibernate on Intel hardware to result in a lot of memory
corruptions on resume.  See for example

dd1ea37d92 drm/i915: change default panel fitting mode to preserve aspect ratio
We did this a long time ago in the DDX driver, but now this fix belongs
in the kernel.

Preserving the aspect ratio is a nicer default.

ee0c6bfbd6 drm/i915: take struct_mutex in i915_dma_cleanup()
intel_cleanup_ring_buffer() calls drm_gem_object_unreference() (as
opposed to drm_gem_object_unreference_unlocked()) so it needs to be
called with "struct_mutex" held.  If we don't hold the lock, it triggers
a BUG_ON(!mutex_is_locked(&dev->struct_mutex));

I also audited the other places that call intel_cleanup_ring_buffer()
and they all hold the lock so they're OK.

This was introduced in: 8187a2b70e "drm/i915: introduce
intel_ring_buffer structure (V2)" and it's a regression from v2.6.34.

2d1c9752ea drm/i915: Fix CRT hotplug regression in 2.6.35-rc1
Commit 7a772c492f has two bugs which
made the hotplug problems on my laptop worse instead of better.

First, it did not, in fact, disable the CRT plug interrupt -- it
disabled all the other hotplug interrupts.  It seems rather doubtful
that that bit of the patch fixed anything, so let's just remove it.
(If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.)

Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64
and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset)
causes a hotplug interrupt about three seconds later.  The old code
never restored PORT_HOTPLUG_EN so this could only happen once, but
they new code restores those registers.  So just set those bits when
we set up the interrupt in the first place.

fe27d53e5c i915: fix ironlake edp panel setup (v4)
The eDP spec claims a 20% overhead for the 8:10 encoding scheme used
on the wire. Take this into account when picking the lane/clock speed
for the panel.

v3: some panels are out of spec, try our best to deal with them, don't
refuse modes on eDP panels, and try the largest allowed settings if
all else fails on eDP.
v4: fix stupid typo, forgot to git add before amending.

1529c69adc ata_generic: implement ATA_GEN_* flags and force enable DMA on MBP 7,1
IDE mode of MCP89 on MBP 7,1 doesn't set DMA enable bits in the BMDMA
status register.  Make the following changes to work around the problem.

* Instead of using hard coded 1 in id->driver_data as class code
  match, use ATA_GEN_CLASS_MATCH and carry the matched id in
  host->private_data.

* Instead of matching PCI_VENDOR_ID_CENATEK, use ATA_GEN_FORCE_DMA
  flag in id instead.

* Add ATA_GEN_FORCE_DMA to the id entry of MBP 7,1.

works fine with ata_generic.  Make ahci ignore the controller on MBP
7,1 and let ata_generic take it for now.
