vline packet parsing function for R600 and Evergreen+ are

out the algorithm into a common function that uses register

As we use a variable length the compiler does not realise that it is a
fixed value of either 2 or 4 bytes. Instead of performing the inline
comparison itself, the compiler inserts a function call to the generic
memcmp routine which is optimised for long comparisons of variable
length. That turns out to be quite expensive...

Okay you don't really want to use udl devices as your console, but if
you are unlucky enough to do so, you run into a lot of schedule while atomic
due to printk being called from all sorts of funky places. So check if we
are in an atomic context, and queue the damage for later, the next printk
should cause it to appear. This isn't ideal, but it is simple, and seems to
work okay in my testing here.
(dirty area idea came from xenfb)
fixes a bunch of sleeping while atomic issues running fbcon on udl devices.

Okay so Alan's patch handled the case where there was no registered fbcon,
however the other path entered in set_con2fb_map pit.
In there we called fbcon_takeover, but we also took the console lock in a couple
of places. So push the console lock out to the callers of set_con2fb_map,
this means fbmem and switcheroo needed to take the lock around the fb notifier
entry points that lead to this.
This should fix the efifb regression seen by Maarten.

"Probably the last feature pull for 3.9, there's some fixes outstanding
thought that I'd like to sneak in. And maybe 3.8 takes a bit longer ...
Anyway, highlights of this pull:
- Kill the horrible IS_DISPLAYREG hack to handle the mmio offset movements
on vlv, big thanks to Ville.
- Dynamic power well support for Haswell, shaves away a bit when only
using the eDP port on pipe A (Paulo). Plus unclaimed register fixes
uncovered by this.
- Clarifications of the gpu hang/reset state transitions, hopefully fixing
a few spurious -EIO deaths in userspace.
- Haswell ELD fixes.
- Some more (pp)gtt cleanups from Ben.
- A few smaller things all over.
Plus all the stuff from the previous rather small pull request:
- Broadcast RBG improvements and reduced color range fixes from Ville.
- Ben is on a "kill legacy gtt code for good" spree, first pile of patches
included.
- No-relocs and bo lut improvements for faster execbuf from Chris.
- Some refactorings from Imre."

Write SR01 to set bit 5 = 1 to disable video output.

Disable the VGA plane via Bit 31 of the MMIO VGA control."
So simply call i915_disable_vga() from i915_redisable_vga().

All display registers should now include the proper offset on VLV.
That means IS_DISPLAYREG() is now useless, and we can eliminate it.

The VGACNTRL register has moved around between different platforms.
To handle the differences add i915_vgacntrl_reg() which returns the
correct offset for the VGACNTRL register.

We can disable (almost) all the display hw if we only use pipe A, with
the integrated edp transcoder on port A. Because we don't set the cpu
transcoder that early (yet), we need to help us with a trick to simply
check for any edp encoders.
v2: Paulo Zanoni pointed out that we also need to configure the eDP
cpu transcoder correctly.

- Rebase patch to be on top of "fix intel_init_power_wells" patch
- Fix typos
- Fix a small bug by adding a "connectors_active" check
- Restore the initial code that unconditionally enables the power
well when taking over from the BIOS
v4: Made by Paulo Zanoni
- One more typo spotted by Jani Nikula
v5: Made by Paulo Zanoni
- Rebase

If the power well is disabled, we should not try to read its
registers, otherwise we'll get "unclaimed register" messages.
V2: Don't check whether the power well is enabled or not, just check
whether we asked it to be enabled or not: if we asked to disable the
power well, don't use the registers on it, even if it's still enabled.
V3: Fix bug that breaks all non-Haswell machines.

The DP_TP_STATUS register for PORT_A doesn't exist. Our documentation
will be fixed soon, so the code does not match it for now.
This solves "Timed out waiting for DP idle patterns" and "unclaimed
register" messages on eDP.
V1: Was called "drm/i915: don't read DP_TP_STATUS(PORT_A)"
V2: Was called "drm/i915: don't send DP idle pattern before normal
pattern on HSW"
V3: Only change the code that touches PORT_A.

We may not concurrently change the power wells code. Which
is already guaranteed since modesets aren't concurrent. That
leaves races against setup/teardown/suspend/resume, and for
those we already (try) rather hard not to hit concurrent
modesets.
No debug WARN_ON added since that would require us to grab the
modeset locks in init/suspend code. Which is again just cargo
culting since just grabbing the locks in those paths isn't good
enough, we need the right order of operations, too.
