Merge tag 'v3.5-rc4' into drm-intel-next-queued
I want to merge the "no more fake agp on gen6+" patches into
drm-intel-next (well, the last pieces). But a patch in 3.5-rc4 also
adds a new use of dev->agp. Hence the backmarge to sort this out, for
otherwise drm-intel-next merged into Linus' tree would conflict in the
relevant code, things would compile but nicely OOPS at driver load :(
Conflicts in this merge are just simple cases of "both branches
changed/added lines at the same place". The only tricky part is to
keep the order correct wrt the unwind code in case of errors in
intel_ringbuffer.c (and the MI_DISPLAY_FLIP #defines in i915_reg.h
together, obviously).

This is just the minimal patch to disable all this code so that we can
do decent amounts of QA before we rip it all out.
The complicating thing is that we need to flush the gpu caches after
the batchbuffer is emitted. Which is past the point of no return where
execbuffer can't fail any more (otherwise we risk submitting the same
batch multiple times).
Hence we need to add a flag to track whether any caches associated
with that ring are dirty. And emit the flush in add_request if that's
the case.
Note that this has a quite a few behaviour changes:
- Caches get flushed/invalidated unconditionally.
- Invalidation now happens after potential inter-ring sync.
I've bantered around a bit with Chris on irc whether this fixes
anything, and it might or might not. The only thing clear is that with
these changes it's much easier to reason about correctness.
Also rip out a lone get_next_request_seqno in the execbuffer
retire_commands function. I've dug around and I couldn't figure out
why that is still there, with the outstanding lazy request stuff it
shouldn't be necessary.
v2: Chris Wilson complained that I also invalidate the read caches
when flushing after a batchbuffer. Now optimized.
v3: Added some comments to explain the new flushing behaviour.

It seems to blow up my ilk in all kinds of strange ways. And now that
we're no longer resetting the entire modeset state, it shouldn't be
necessary any longer.
This essentially reverts

drm/i915: re-init modeset hw state after gpu reset
safe for the introduction of modeset_init_hw, that one is nice to
prevent code duplication between driver load and resume.
v2: Add a comment to the code to warn future travellers of the dragon
dungeon ahead, suggested by Chris Wilson.

The idr code already passes us the pointer associated with that id, so
no need to look it up again. Also, we'll kill the idr right away, so
there's no issue with leaving these dangling pointers behind - the
current code does the same.
v2: Also drop the file argument, spotted by Ben Widawsky.

It doesn't hurt and it at least prevents us from OOPSing left and
right at quite a few places. This also allows us to simplify the code
a bit by folding the only line of context_open into the callsite.
We obviuosly also need to run the cleanup code unconditionally, too.

Date: Mon Jun 4 14:42:56 2012 -0700
drm/i915: reset the GPU on context fini
broke module unload because it reset the gpu before we've stopped
touching it. Later on in the unload sequence the ringbuffer code
complained that the gpu would idle properly (because intel_gpu_reset
only resets the hw and not our sw state).
v2: Reorder things so that we reset the gpu _before_ we release the
backing storage of the default context.

One small bug fix, plus a rename of all the ST Ericsson regulators in
the device tree since all the device trees had been written with
different names and some infelicities in the test proceedures meant that
the device tree code had apparently never actually been run against the
upstream device tree.

Currently, the index of "Dock-desk" and "Dock-card" are the same.
Thus the latter one overrides the first one.
Then we have problem when calling extcon_find_cable_index() because
edev->supported_cable[7] only matches "Dock-card".
