b705120e41 drm/i915: Use consistent mappings for OpRegion between ACPI and i915
The opregion is a shared memory region between ACPI and the graphics
driver. As the ACPI mapping has been changed to cachable in commit
6d5bbf00d2, mapping the intel opregion
non-cachable now fails. As no bus-master hardware is involved in the
opregion, cachable map should do no harm.

Tested on a Fujitsu Lifebook P8010.

934f992c76 drm/i915: Recognise non-VGA display devices
Starting with SandyBridge (though possible with earlier hacked BIOSes),
the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior,
it would simply disable the integrated GPU. So we adjust our PCI class
mask to match any DISPLAY_CLASS device.

In such a configuration, the IGFX is not a primary VGA controller and
so should not take part in VGA arbitration, and the error return from
vga_client_register() is expected.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

d7b9935a34 i915: Fix i915 suspend delay
During system suspend, the "wait for ring buffer to empty" loop would
always time out after three seconds, because the faster cached ring
buffer head read would always return zero.  Force the slow-and-careful
PIO read on all but the first iterations of the loop to fix it.

This also removes the unused (and useless) 'actual_head' variable that
tried to approximate doing this, but did it incorrectly.

c7dca47bd6 drm/i915/ringbuffer: Fix use of stale HEAD position whilst polling for space
During suspend, Linus found that his machine would hang for 3 seconds,
and identified that intel_ring_buffer_wait() was the culprit:

"Because from looking at the code, I get the notion that
"intel_read_status_page()" may not be exact. But what happens if that
inexact value matches our cached ring->actual_head, so we never even
try to read the exact case? Does it _stay_ inexact for arbitrarily
long times? If so, we might wait for the ring to empty forever (well,
until the timeout - the behavior I see), even though the ring really
_is_ empty."

As the reported HEAD position is only updated every time it crosses a
64k boundary, whilst draining the ring it is indeed likely to remain one
value. If that value matches the last known HEAD position, we never read
the true value from the register and so trigger a timeout.

4efe070896 drm/i915: make the blitter report buffer modifications to the FBC unit
Without this change, blits to the front buffer won't invalidate FBC
state, causing us to scan out stale data.  Make sure we update these
bits on every FBC enable, since they may get clobbered if we shut off
the display.

1ffa325bac drm/i915: set more FBC chicken bits
Add a couple of missing workaround bits for ILK & SNB.  These disable
clock gating on a couple of units that would otherwise prevent FBC from
working.

25b2ec5b64 drm/radeon/kms: balance asic_reset functions
First, we were calling mc_stop() at the top of the function
which turns off all MC (memory controller) clients,
then checking if the GPU is idle.  If it was idle we
returned without re-enabling the MC clients which would
lead to a blank screen, etc.  This patch checks if the
GPU is idle before calling mc_stop().

Second, if the reset failed, we were returning without
re-enabling the MC clients.  This patch re-enables
the MC clients before returning regardless of whether
the reset was successful or not.

d42dd579ac drm/radeon/kms: add module option for pcie gen2
Switching to pcie gen2 causes problems on some
boards.  Add a module option to turn it on/off.

There are gen2 compatability issues with some
motherboards it seems.

3632ef8909 Revert "drm: Update fbdev fb_fix_screeninfo"
This reverts commit dfe63bb0ad.

This commit was causing nouveau not to work properly, for -rc1 I'd
prefer it worked and we can look if this is useful for 2.6.39.

1591192d3a drm/i915: Disable GPU semaphores on SandyBridge mobile
Hopefully, this is a temporary measure whilst the root cause is
understood. At the moment, we experience a hard hang whilst looping
urbanterror that has been identified as a result of the use of
semaphores, but so far only on SNB mobile.
