It's been 5 years since kms support was merged and roughly 4 years
since UMS support was ripped out from userspace drivers.

Thus far it's not been a big burden to keep the ums paths alive, and
we've made some good progress in better separating it from the kms
code by sprinkling DRIVER_MODESET checks all over the place.

But now that the drm demidlayering is within reach this changes. I
want to make the driver loading code more robust using devres.c and
other cool tricks. But that doesn't work with ums due to the
shadow-attach trick. Which means we either
a) need to split out a complete ums codebase like radeon has
b) kill it for good.

The 2nd option is obviously much less work than the first, so I think
it's time to test the waters and see how many people out there still
use ums.

I've decided that silently failing to initialize the driver (and not
e.g. failing to load the module) is the right thing. That way we
should only get reports from users that actually care about some ums
features (like accelerated gl or support for secondary outputs).
Everyone else will just fall back to the vesa X driver.

For developers there's a small info level dmesg output.

The plan is to drop this Kconfig option after 3.16 (so gives us 2 full
releases) and then start killing code for real 2-3 releases
afterwards. That should be more than enough time for users to pipe up.

Of course if anyone does we need to revisit this plan and maybe go
with option a) above.

Also enable the KMS support by default in Kconfig and polish the help
texts a bit.

v2: Add the missing hunk of actual code changes. Oops. (Ville)

Thus far we've tried to carefully work around the fact that old
userspace relied on the AGP-backed legacy buffer mapping ioctls for a
bit too long. But it's really horribly, and now some new users for it
started to show up again:

http://www.mail-archive.com/mesa-dev@lists.freedesktop.org/msg45547.html

This uses drmAgpSize to figure out the GTT size, which is both the
wrong thing to inquire and also might force us to keep this crap
around for another few years.

So I want to stop this particular zombie from raising ever again. Now
it's only been 4 years since XvMC was fixed for gen3, so a bit early
by the usual rules. But since Linus explicitly said that an ABI
breakage only counts if someone actually observes it I want to tempt
fate an accelarate the demise of AGP.

We probably need to wait 2-3 kernel releases with this shipping until
we go on a killing spree code-wise.

Some VLV PHY/PLL DPIO registers have group/lane/channel access.  Current
DPIO register definition doesn't have a structure way to break them
down. As a result it is not easy to match the PHY/PLL registers with the
configdb document.  Rename those registers based on the configdb for easy
cross references, and without the need to check the offset in the header
file.

New format is as following.

<platform name>_<DPIO component><optional lane #>_DW<dword # in the
doc>_<optional channel #>

For example,

VLV_PCS_DW0 - Group access to PCS for lane 0 to 3 for PCS DWORD 0.
VLV_PCS01_DW0_CH0 - PCS access to lane 0/1, channel 0 for PCS DWORD 0.

Another example is

VLV_TX_DW0 - Group access to TX lane 0 to 3 for TX DWORD 0
VLV_TX0_DW0 - Refer to TX Lane 0 access only for TX DWORD 0.

There is no functional change on this patch.

v2: Rebase based on previous patch change.
v3: There may be configdb different version that document the start DW
differently. Add a comment to clarify.  Fix up some mismatch start DW
for second PLL block. (Ville)

All rather simple adjacent lines changed or partial backports from

  scripts/kallsyms: filter symbols not in kernel address space

A vmalloc fault needs to sync up PGD/PTE entry from init_mm to current
task's "active_mm".  ARC vmalloc fault handler however was using mm.

A vmalloc fault for non user task context (actually pre-userland, from
init thread's open for /dev/console) caused the handler to deref NULL mm
(for mm->pgd)

The reasons it worked so far is amazing:

1. By default (!SMP), vmalloc fault handler uses a cached value of PGD.
   In SMP that MMU register is repurposed hence need for mm pointer deref.

2. In pre-3.12 SMP kernel, the problem triggering vmalloc didn't exist in
