changes all over.
I've got one outstanding vmwgfx pull that touches mm so kept it

This is only used by drm_irq_install(), which is an optional helper.
For legacy pci devices this is required (due to interrupt sharing without
msi/msi-x), and just making this the default exactly matches the behaviour
of all existing drivers using the drm_irq_install() helpers. In case that
ever becomes wrong drivers can roll their own irq handling, as many
drivers already do (for other reasons like needing a threaded interrupt
handler, or having an entire pile of different interrupt sources).

pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.
Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().
Add domain parameter to CDV_MSG_READ32, CDV_MSG_WRITE32, MRST_MSG_READ32,
MRST_MSG_WRITE32, MDFLD_MSG_READ32, MDFLD_MSG_WRITE32.
Extract pci_dev from struct drm_device and use pdev to find the domain
number while calling pci_get_domain_bus_and_slot().

There is no need to #define the license of the driver, just put it in
the MODULE_LICENSE() line directly as a text string.
This allows tools that check that the module license matches the source
code license to work properly, as there is no need to unwind the
unneeded dereference, especially when the string is defined in a .h file
far away from the .c file it is used in.

The magic switching between proper pci driver and shadow-attach isn't
useful anymore since there's no ums+kms drivers left. Let's split this
up properly, calling pci_register_driver for kms drivers and renaming
the shadow-attach init to drm_legacy_pci_init/exit.

The functions pci_dev_put() and psb_intel_i2c_destroy() test whether
their argument is NULL and then return immediately.
Thus the tests around their calls are not needed.

drm: Rework vblank-wait handling to allow interrupt reduction.
to stay backwards-compatible with old UMS code that didn't even tell
the kernel when it did a modeset, so that the kernel could
save/restore vblank counters. At worst this means vblanks will be
somewhat funky on a setup that very likely no one still runs.
So let's just nuke it.
Plan B would be to set it unconditionally in drm_vblank_init for kms
drivers, instead of in each driver separately. So if this patch breaks
anything please only restore the hunks in drmP.h and drm_irq.c, plus
add a check for DRIVER_MODESET in drm_vblank_init.
Stumbled over this in a discussion on irc with Chris.

One step closer to dropping all the drm_bus_* code:
Add a driver->set_busid() callback and make all drivers use the generic
helpers. Nouveau is the only driver that uses two different bus-types with
the same drm_driver. This is totally broken if both buses are available on
the same machine (unlikely, but lets be safe). Therefore, we create two
different drivers for each platform during module_init() and set the
set_busid() callback respectively.

Unfortunately this requires a drm-wide change, and I didn't see a sane
way around that. Luckily it's fairly simple, we just need to inline
the respective get_irq implementation from either drm_pci.c or
drm_platform.c.
With that we can now also remove drm_dev_to_irq from drm_irq.c.

All drivers embed gem-objects into their own buffer objects. There is no
reason to keep drm_gem_object_alloc(), gem->driver_private and
->gem_init_object() anymore.
New drivers are highly encouraged to do the same. There is no benefit in
allocating gem-objects separately.

So I've stumbled over drm_fasync and wondered what it does. Digging
that up is quite a story.
First I've had to read up on what this does and ended up being rather
bewildered why peopled loved signals so much back in the days that
they've created SIGIO just for that ...
Then I wondered how this ever works, and what that strange "No-op."
comment right above it should mean. After all calling the core fasync
helper is pretty obviously not a noop. After reading through the
kernels FASYNC implementation I've noticed that signals are only sent
out to the processes attached with FASYNC by calling kill_fasync.
No merged drm driver has ever done that.
After more digging I've found out that the only driver that ever used
this is the so called GAMMA driver. I've frankly never heard of such a
gpu brand ever before. Now FASYNC seems to not have been the only bad
thing with that driver, since Dave Airlie removed it from the drm
driver with prejudice:
commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed
Author: Dave Airlie <airlied@linux.ie>
Date: Sun Aug 29 12:04:35 2004 +0000
Drop GAMMA DRM from a great height ...
Long story short, the drm fasync support seems to be doing absolutely
nothing. And the only user of it was never merged into the upstream
kernel. And we don't need any fops->fasync callback since the fcntl
implementation in the kernel already implements the noop case
correctly.
So stop this particular cargo-cult and rip it all out.
v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers
(somehow I've missed that one in staging). Also drop the reference in
the drm DocBook. ARM compile-fail reported by Rob Clark.
v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this
patch here.
v4: Actually git add ... tsk.

All the gem based kms drivers really want the same function to
destroy a dumb framebuffer backing storage object.
So give it to them and roll it out in all drivers.
This still leaves the option open for kms drivers which don't use GEM
for backing storage, but it does decently simplify matters for gem
drivers.
