three fixes for i915.
* tag 'drm-intel-next-fixes-2015-04-25' of git://anongit.freedesktop.org/drm-intel:
drm/i915: vlv: fix save/restore of GFX_MAX_REQ_COUNT reg
drm/i915: Workaround to avoid lite restore with HEAD==TAIL
drm/i915: cope with large i2c transfers
Due this typo we don't save/restore the GFX_MAX_REQ_COUNT register across
suspend/resume, so fix this.
This was introduced in
commit ddeea5b0c3

drm/i915: vlv: add runtime PM support
I noticed this only by reading the code. To my knowledge it shouldn't
cause any real problems at the moment, since the power well backing this
register remains on across a runtime s/r. This may change once
system-wide s0ix functionality is enabled in the kernel.
v2:
- resend after a missing git add -u :/

WaIdleLiteRestore is an execlists-only workaround, and requires the driver
to ensure that any context always has HEAD!=TAIL when attempting lite
restore.
Add two extra MI_NOOP instructions at the end of each request, but keep
the requests tail pointing before the MI_NOOPs. We may not need to
executed them, and this is why request->tail is sampled before adding
these extra instructions.
If we submit a context to the ELSP which has previously been submitted,
move the tail pointer past the MI_NOOPs. This ensures HEAD!=TAIL.
v2: Move overallocation to gen8_emit_request, and added note about
sampling request->tail in commit message (Chris).
v3: Remove redundant request->tail assignment in __i915_add_request, in
lrc mode this is already set in execlists_context_queue.
Do not add wa implementation details inside gem (Chris).
v4: Apply the wa whenever the req has been resubmitted and update
comment (Chris).

The hardware, according to the specs, is limited to 256 byte transfers,
and current driver has no protections in case users attempt to do larger
transfers. The code will just stomp over status register and mayhem
ensues.
Let's split larger transfers into digestable chunks. Doing this allows
Atmel MXT driver on Pixel 1 function properly (it hasn't since commit
9d8dc3e529 "Input: atmel_mxt_ts -
implement T44 message handling" which tries to consume multiple
touchscreen/touchpad reports in a single transaction).

At present, dma_buf_export() takes a series of parameters, which
makes it difficult to add any new parameters for exporters, if required.
Make it simpler by moving all these parameters into a struct, and pass
the struct * as parameter to dma_buf_export().
While at it, unite dma_buf_export_named() with dma_buf_export(), and
change all callers accordingly.

The merge is clean, but the arm build fails afterwards,
due to API changes in the regulator tree.

platform_get_irq() can return negative error values and we already test for
these. Therefore the variable holding this value should be signed to not
loose possible error values.
