b6ae906b04 V4L/DVB: v4l: mem2mem_testdev: fix g_fmt NULL pointer dereference
Calling g_fmt before s_fmt resulted in a NULL pointer dereference as no
default formats were being selected on probe.

Issuing a GET_MIN request on the power line frequency control times out
on at least the Apple iSight. As the UVC specification doesn't list
GET_MIN/MAX/RES as supported on that control, remove them from the
uvc_ctrls array.

We should initialize the module dynamic debug datastructures
only after determining that the module is not loaded yet. This
fixes a bug that introduced in 2.6.35-rc2, where when a trying
to load a module twice, we also load it's dynamic printing data
twice which causes all sorts of nasty issues. Also handle

446a5a8b1e ARM: 6205/1: perf: ensure counter delta is treated as unsigned
Hardware performance counters on ARM are 32-bits wide but atomic64_t
variables are used to represent counter data in the hw_perf_event structure.

The armpmu_event_update function right-shifts a signed 64-bit delta variable
and adds the result to the event count. This can lead to shifting in sign-bits
if the MSB of the 32-bit counter value is set. This results in perf output
such as:

 Performance counter stats for 'sleep 20':

 18446744073460670464  cycles             <-- 0xFFFFFFFFF12A6000
        7783773  instructions             #      0.000 IPC
            465  context-switches
            161  page-faults
        1172393  branches

   20.154242147  seconds time elapsed

This patch ensures that the delta value is treated as unsigned so that the
right shift sets the upper bits to zero.

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.

41c310447f amd64_edac: Fix syndrome calculation on K8
When calculating the DCT channel from the syndrome we need to know the
syndrome type (x4 vs x8). On F10h, this is read out from extended PCI
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.

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.

adcdbc6651 drm/i915: don't access FW_BLC_SELF on 965G
The register offset for FW_BLC_SELF is a totally different set of bits
on Broadwater (it's actually MI_RDRET_STATE), so don't treat it like
FW_BLC_SELF on 965G chips.

Fixes bug https://bugs.freedesktop.org/show_bug.cgi?id=26874.

43ed340ad9 drm/i915: Account for space on the ring buffer consumed whilst wrapping.
If we fill the tail of the physical ring buffer with NOOP when wrapping,
we need to account for the reduction in available space.

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.

c6353b4520 ahci,ata_generic: let ata_generic handle new MBP w/ MCP89
For yet unknown reason, MCP89 on MBP 7,1 doesn't work w/ ahci under
linux but the controller doesn't require explicit mode setting and
works fine with ata_generic.  Make ahci ignore the controller on MBP
7,1 and let ata_generic take it for now.

Reported in bko#15923.

  https://bugzilla.kernel.org/show_bug.cgi?id=15923

NVIDIA is investigating why ahci mode doesn't work.
