fix, 2 qxl crasher fixes, and a couple of minor cleanups.
I may have a new AMD hw support branch next week, its one of those
doesn't affect anything existing just adds new support, I'll see how

drm/qxl: drop active_user_framebuffer as its unneeded
qxl: drop unused variable.
drm/qxl: fix ioport interactions for kernel submitted commands.
drm: remove unused wrapper macros
drm/radeon: check incoming cliprects pointer
When UMS was deprecated it removed support for nomodeset commandline
we really want this in distro land so we can debug stuff, everyone
should fallback to vesa correctly.
v2: oops -1 isn't used anymore, restore original behaviour
-1 is default, so we can boot with nomodeset on the command line,
then use radeon.modeset=1 to override it for debugging later.

So qxl has ioports, but it really really really doesn't want you
to write to them twice, but if you write and get a signal before
the irq arrives to let you know its completed, you have to think
ahead and avoid writing another time.
However this works fine for update area where really multiple
writes aren't the end of the world, however with create primary
surface, you can't ever do multiple writes. So this stop internal
kernel writes from doing interruptible waits, because otherwise
we have no idea if this write is a new one or a continuation of
a previous one.

Pfit state readout is a bit ugly on gen2/3 due to the intermingling

The original line,

MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into
MGA1064_PIX_CLK_CTL. Change the line to write properly into
MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use
the same pattern (but work correctly), so this patch updates them all
to use this new (slightly more efficient) write pattern. The WREG_DAC

twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX

TV-out uses the same reference clock as everyone else. The only
difference seems to be in the slightly different CB tuning limit.
Note that PLL_REF_INPUT_TVCLKINBC is a reserved value on ilk+. Also
strictly speaking we don't support native TV-out on ilk+, hence all
that code is dead. But Bspec still contains some residual mentions of
native TV-out on some pch-split platforms, so I've figured it doesn't
hurt to keep the code around a bit longer (e.g. in the cb tune
function).

This reverts commit 03752f5b7b.
This revert requires a bit of explanation on how I understand things
work. Internally the architects/designers decide how the stolen encoding
works. We put it in a doc. BIOS writers take these docs and implement
it. Driver writers read the doc too, and read the value left by the BIOS
writers, and then we make magic.
The failing here is that in the docs we had[1] contained two different
definitions for this register for Gen7. (We have both a PCI register,
and an MMIO, and each of these were different). At the time [2] of
03752f5, we asked the architects what the correct value should be; but
that doesn't match the reality (BIOS) unfortunately.
So on all machines I can get my hands on, this revert is the right thing
to do. I've also worked with the product group to confirm that they
agree this revert is what we should do. People using HW made my "people"
who both write their own BIOS, and have access to our docs (Apple?).
Investigations are still ongoing about whether we need to add a list
of machines needing special handling, but this patch should be the
right thing for pretty much everyone.
[1] The docs are still wrong on this one. Now instead of two registers with
two definitions, we have one register with BOTH definitions, progress?
[2] The open source PRMs have the "wrong" definitions in chapter Volume
1 part6, section 1.1.12.
This digging was inspired by Paulo.

Because PPGTT PDEs within the GTT are calculated in cachelines
(HW guys consistency ftw) we do a divide which will wreak havoc if this
is wrong, and I know that from experience).
If/when we move to multiple PPGTTs this will have to become a WARN, and
return an error. For now however it should always be considered fatal,
and only a developer could hit it.

Because our context refcounting doesn't grab a ref at lookup time, it is
unsafe to do so without the lock.
NOTE: We don't have an easy way to put the assertion in the lookup
function which is where this really belongs. Context switching is good
enough because it actually asserts even more correctness by protecting
the default_context.

In order to be notified of when the context and all of its associated
objects is idle (for if the context maps to a ppgtt) we need a callback
from the retire handler. We can arrange this by using the kref_get/put
of the context for request tracking and by inserting a request to
demarque the switch away from the old context.

According to BSpec the link training sequence for eDP on HSW port-A
should be as follows:
1. link training: clock recovery
2. link training: equalization
3. link training: set idle transmission mode
4. display pipe enable
5. link training: disable (set normal mode)
Contrary to this at the moment we don't do step 3. and we do step 5.
before step 4. Fix this by setting idle transmission mode for eDP at
the end of intel_dp_complete_link_train and adding a new
intel_dp_stop_link_training function to disable link training. With
these changes we'll end up with the following functions corresponding
to the above steps:
intel_dp_start_link_train -> step 1.
intel_dp_complete_link_train -> step 2., step 3.
intel_dp_stop_link_train -> step 5.
For port-A we'll call intel_dp_stop_link_train only after enabling the
pipe, for everything else we'll call it right after
intel_dp_complete_link_train to preserve the current behavior.
Tested on HSW/HSW-ULT.
In v2:
- Due to a HW issue we must set idle transmission mode for port-A too
before enabling the pipe. Thanks for Arthur Runyan for explaining
this.
- Update the patch subject to make it clear that it's an eDP fix, DP is
not affected.
v3:
- rename intel_dp_link_train() to intel_dp_set_link_train(), use 'val'
instead 'l' as var name. (Paulo)

Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.
- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.
- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.
- bigger driver cleanups for designware, s3c2410
- removing superfluous refcounting from drivers
- removing Ben Dooks as second maintainer due to inactivity. Thanks
