The driver requires shmfs as the backing filesystem to handle the buffer

Fixes: Bug 14662 - Dell E5500 kernel panic with KMS
http://bugzilla.kernel.org/show_bug.cgi?id=14662
The revealing nature of the panic is the NULL function pointer
dereference in read_cache_page_async().

For CRT hotplug detect status, we have four test results as blue
channel only, green channel only, both blue and green channel, and
no channel attached. Origin code only marks both blue and green channel
case as connected, but ignore other possible connected states. This one
trys to detect CRT by checking no channel attached case instead.

There is a problem in the quirk tables used by tpacpi_is_fw_known() and
tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking
the EC firmware ID DMI field to never match.
This breaks module loading on, e.g. a T23 with outdated BIOS, and the
module will refuse to load unless the "force_load=1" parameter is given.
Fix the quirk tables so that they can also match the outdated BIOSes,
which in turn will both fix the module loading, and also warn the user
that he is using outdated firmware and should upgrade.
This fixes a serious regression, introduced by commit
e675abafcc0df38125e6e94a9ba91c92fe774f52, "thinkpad-acpi: be more strict
when detecting a ThinkPad".

When the framebuffer driver does not publish detailed timing information
for the current video mode, the correct value for the pixclock field is
zero, not -1.
Since pixclock is actually unsigned, the value -1 would be interpreted
as 4294967295 picoseconds (i.e., about 4 milliseconds) by
register_framebuffer() and userspace programs.
This patch allows X.org's fbdev driver to work.

Some architectures compute ->vm_page_prot depending on ->vm_flags, so we
need to update the protections after adjusting the flags.
AFAIK this only affects running X under Xen; without this patch you get
lots of coloured blobs on the screen, or maybe a complete lockup. Or
anything really.
But that still depends on lots of out-of-tree stuff, so I don't think
there are any consequences for anyone else. But it is wrong in principle.

On broken EDID we were reporting vga connector to be disconnected
even if ddc probe did found a monitor. This patch report that the
connector is connected on such case. This allow drm to add a fail
safe mode (800x600 at the time of this patch) thus user can boot
and later add a mode which match its monitor capabilities.

unused_nodes modification needs to be protected by unused_lock spinlock.
Here is an example of an usage where there is no such protection without
this patch.
Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list)
2-spin_lock(spinlock protecting mm struct)
3-drm_mm_put_block(this function might modify unused_nodes
list but doesn't protect modification with unused_lock)
4-spin_unlock(spinlock protecting mm struct)
Process2: 1-drm_mm_pre_get(this function modify unused_nodes list)
At this point Process1 & Process2 might both be doing modification to
unused_nodes list. This patch add unused_lock protection into
drm_mm_put_block to avoid such issue.

RS400,RC410,RS480 chipset seems to report a lot of false positive
with load detect on TV output. We haven't yet found a way to make
load detect reliable on those chipset, thus just disable it for TV
output. Would avoid user to experience phantom screen because X
believe there is a monitor connected to the TV output.

This fixes RH bugzilla #527874.
On resume the atom posting wasn't working, however vbe posting was
going fine, after 2 weeks over irc, and 8 hrs with the hardware,
I tracked it down to the memory device table and it access the MC
registers via IIO, it appears the rv515 atom iio table might not
be fully functional, so adding a readback before doing a write
either provides enough delay to make things resume correctly.
Thanks to Peng Huang at Red Hat for coming to Brisbane.

AGP resume was broken since we moved to the new init path,
because we never re-enabled AGP on these systems at resume time.
This patch just calls the AGP resume call which just does the reinit
at resume time like the old path did.
Since AGP is pretty much gpu independant I did it outside
the gpu specific code.

1/ Error handling code following a kzalloc should free the allocated data.
2/ Report an error when no platform data is detected
Both problems fixed by moving the platform data check before the allocation,
and allows a goto to be killed.

The completion of a pq operation is notified with a null descriptor
appended to the end of the chain. This descriptor needs to be visible
to dma clients otherwise the client is precluded from ensuring all
operations are quiesced before freeing channel resources, i.e. due to
descriptor polling it may get the completion notification ahead of the
interrupt delivered by the null descriptor.

ioat3.2 does not support asynchronous error notifications which makes
the driver experience latencies when non-zero pq validate results are
expected. Provide a mechanism for turning off async_xor_val and
async_syndrome_val via Kconfig. This approach is generally useful for
any driver that specifies ASYNC_TX_DISABLE_CHANNEL_SWITCH and would like
to force the async_tx api to fall back to the synchronous path for
certain operations.

<4GiB RAM.
Commit 86cf898e1d0fca245173980e3897580db38569a8 ("intel-iommu: Check for
'DMAR at zero' BIOS error earlier.") was supposed to work by pretending
not to detect an IOMMU if it was actually being reported by the BIOS at
physical address zero.
However, the intel_iommu_init() function is called unconditionally, as
are the corresponding functions for other IOMMU hardware.
So the patch only worked if you have RAM above the 4GiB boundary. It
caused swiotlb to be initialised when no IOMMU was detected during early
boot, and thus the later IOMMU init would refuse to run.
But if you have less RAM than that, swiotlb wouldn't get set up and the
IOMMU _would_ still end up being initialised, even though we never
claimed to detect it.
This patch also sets the dmar_disabled flag when the error is detected
during the initial detection phase -- so that the later call to
intel_iommu_init() will return without doing anything, regardless of
whether swiotlb is used or not.
