This patch fixes erroneous register read.
reall function needs register base address + offset but
exynos_drm_gsc module used only offset to read a register.
so this patch uses gsc_read function instead of readl.

This patch fixes the issue that when buffer allocation is requested
without iommu, the allocation is failed.
Without iommu, dma_alloc_attrs function allocates some memory region
and returns cpu address so this patch makes the cpu address to be set
to buf->kvaddr correctly.
Changelog v2:
- fix buffer free
. Without iommu, dma_free_attrs function requires kernel space address
as argument. So it changes the argument, buf->pages to buf->kvaddr.

Some fixes for 3.8:
- Watermark fixups from Chris Wilson (4 pieces).
- 2 snb workarounds, seem to be recently added to our internal DB.
- workaround for the infamous i830/i845 hang, seems now finally solid!
Based on Chris' fix for SNA, now also for UXA/mesa&old SNA.
- Some more fixlets for shrinker-pulls-the-rug issues (Chris&me).
- Fix dma-buf flags when exporting (you).
- Disable the VGA plane if it's enabled on lid open - similar fix in
spirit to the one I've sent you last weeek, BIOS' really like to mess
with the display when closing the lid (awesome debug work from Krzysztof
Mazur).

The mmap offset structure is not part of the drm/i915 code, but
provided by gem helpers. To avoid leaky abstractions (by either
depending upon implementation details of said helper wrt to
preallocations, or reimplementing it in our code and so fuzzing
around in internal details of that helpr) simply disable
the shrinker lock stealing accross calls into the helper functions.
This should fix igt/gem_tiled_swapping.

commit 5774506f15
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Wed Nov 21 13:04:04 2012 +0000
drm/i915: Borrow our struct_mutex for the direct reclaim
added a nice trick to steal the struct_mutex lock in the shrinker if
it's the current task holding it. But this also caused the requirement
that every place which allocates memory needs to be careful about the
gem state of objects, since the shrinker could have pulled the rug out
from under it. We've usually solved this by carefully preallocating
things or ensure that buffers are pinned already.
But the shrinker also reaps mmap offset, so allocating those needs to
be careful, too. Now that code has been factored out into some common
helpers, so either we have fragile code depending upon the common
helper not doing something we don't want it to do. Or we need to
reimplement the mmap offset creation and so also leak implementation
details into our code.
Since this all results in leaky abstraction, cop out by disabling the
lock borrowing trick while calling down into the helpers. That way our
craziness is nicely confined to files in drm/i915.
v2: Split out the change to create_mmap_offset as request by Chris Wilson.

radeon_fence_wait_empty_locked should not trigger GPU reset as no
place where it's call from would benefit from such thing and it
actually lead to a kernel deadlock in case the reset is triggered
from pm codepath. Instead force ring completion in place where it
makes sense or return early in others.
