Use minor->index to label things, not the name field from the proc_dir_entry
of the /proc/dwm/<minor>/ directory.
Also, use "%u" not "%d" to render the value and use a 12-byte buffer in which
to render the integer, not a 16-byte buffer. The longest string an unsigned
int can give you is 10 chars (4294967295) plus a NUL, so round up to 12 as the
stack is likely to be 4- or 8-byte aligned.

Currently we have a problem with this:
1. i915: create gem object
2. i915: export gem object to prime
3. radeon: import gem object
4. close prime fd
5. radeon: unref object
6. i915: unref object
i915 has an imported object reference in its file priv, that isn't
cleaned up properly until fd close. The reference gets added at step 2,
but at step 6 we don't have enough info to clean it up.
The solution is to take a reference on the dma-buf when we export it,
and drop the reference when the gem handle goes away.
So when we export a dma_buf from a gem object, we keep track of it
with the handle, we take a reference to the dma_buf. When we close
the handle (i.e. userspace is finished with the buffer), we drop
the reference to the dma_buf, and it gets collected.
This patch isn't meant to fix any other problem or bikesheds, and it doesn't
fix any races with other scenarios.
v1.1: move export symbol line back up.
v2: okay I had to do a bit more, as the first patch showed a leak
on one of my tests, that I found using the dma-buf debugfs support,
the problem case is exporting a buffer twice with the same handle,
we'd add another export handle for it unnecessarily, however
we now fail if we try to export the same object with a different gem handle,
however I'm not sure if that is a case I want to support, and I've
gotten the code to WARN_ON if we hit something like that.
v2.1: rebase this patch, write better commit msg.
v3: cleanup error handling, track import vs export in linked list,
these two patches were separate previously, but seem to work better
like this.
v4: danvet is correct, this code is no longer useful, since the buffer
better exist, so remove it.
v5: always take a reference to the dma buf object, import or export.
(Imre Deak contributed this originally)
v6: square the circle, remove import vs export tracking now
that there is no difference

There is no way to use modes added to the user_modes list. We never
look at the contents of said list in the kernel, and the only operations
userspace can do are attach and detach. So the only "benefit" of this
interface is wasting kernel memory.
Fortunately it seems no real user space application ever used these
ioctls. So just kill them.
Also remove the prototypes for the non-existing drm_mode_addmode_ioctl()
and drm_mode_rmmode_ioctl() functions.
v2: Use drm_noop instead of completely removing the ioctls

compare the clock or vrefresh values. drm_mode_equal() is now

Some devices (ATI/AMD cards) don't support passing ELD struct to the
hardware but just require filling specific registers and then the
hardware/firmware does the rest. In such cases we need to read the info
from SAD blocks and put them in the correct registers.

Since I expect Linus to open the merge window in about a week I guess this
is the last i915 feature pull for 3.10. Highlights:
Updated testing tree for -next. Highlights:
- Corner case fixes discovered with static analyzers (Damien).
- More fixes to combat unclaimed register errors on Haswell (Paulo).
- Some small fixes to the gpu turbo code (Rodrigo+Ben), Ben has more
fixes for overclocking support pending.
- More prep work for fastboot from Chris.
- VT-switchless suspend/resume from Jesse.
- The prep work of Egbert Eich's hpd irq storm handling. Hopefully we can
squeeze in the actual storm handling code for 3.10 ...
- More convenience helpers for Imre's sg iterator. Core parts acked by
Andrew Morton.
- A bit of backlight code cleanup from Jani.
- Fixed ilk gpu reset (Jesse).
- Reduced color range handling fixes for VLV (Ville).
The big item here is though the introduction of pipe_config to properly
pre-compute the desired modeset state before touching the hw. Together
with some very basic support to read out the current config from the hw
and compare the state with the sw tracking. This is all prep work for more
reliable fastboot, atomic modesets and other cool features. Stuff
converted to the new world includes:
- Most simple pipe attributes (reduce color range, pixel multiplier).
- Pipe bpp/dither handling.
- Some convenience flags like ->has_pch_encoder to simplify the code flow.
- (Almost) DP clock handling, had to be reverted since part of a prep
patch was lost in rebasing ...
Expect a lot of patches for this throughout 3.11, there's tons of work

of patches for this throughout 3.11, there's tons of work till we have all
state properly tracked for fastbooting to work.
For 3.10 I have a bunch of fixes queued up and I plan to send them all out
at the end of this week. I need to shuffle patches in my -next queue a bit
so that we don't but feature-y stuff in there, too. The main thing I'd
like to sneak in is Egbert's hpd irq storm handling, which should be
pretty low-risk since all the infrastructure work has landed already. I
also have the oops fix pending, but that only mustered review before the
w/e and giving how hairy that part of our modeset code is, I want to give
it some more testing before forwarding.
Note: annarchy.fd.o seems to run out of disk space, so couldn't push the
usual for-airlied branch. Tag should work though.
Note 2: I've had to do a backmerge since conflicts grew too ugly, but the
upstream -rc I've backmerged is already in your drm-next.

Rather than building a config which may or may not work, let the driver
build an initial fb config. This allows the driver to use the BIOS boot
configuration for example, displaying kernel messages and the initial fb
console on the same outputs the BIOS lit up at boot time. If that
fails, the driver can still fall back the same way as the core.

So here's my promised pile of fixes for 3.9. I've dropped the core prep
patches for vt-switchless suspend/resume as discussed on irc. Highlights:
- Fix dmar on g4x. Not really gfx related, but I'm fed up with getting
blamed for dmar crapouts.
- Disable wc ptes updates on ilk when dmar is enabled (Chris). So again,
dmar, but this time gfx related :(
- Reduced range support for hsw, using the pipe CSC (Ville).
- Fixup pll limits for gen3/4 (Patrick Jakobsson). The sdvo patch is
already confirmed to fix 2 bug reports, so added cc: stable on that one.
- Regression fix for 8bit fb console (Ville).
- Preserve lane reversal bits on DDI/FDI ports (Damien).
- Page flip vs. gpu hang fixes (Ville). Unfortuntely not quite all of
them, need to decide what to do with the currently still in-flight ones.
- Panel fitter regression fix from Mika Kuoppala (was accidentally left on
on some pipes with the new modset code since 3.7). This also improves
the modeset sequence and might help a few other unrelated issues with
lvds.
- Write backlight regs even harder ... another installement in our eternal
fight against the BIOS and backlights.
- Fixup lid notifier vs. suspend/resume races (Zhang Rui). Prep work for
new ACPI stuff, but closing the race itself seems worthwile on its own.
- A few other small fixes and tiny cleanups all over.
Lots of the patches are cc: stable since I've stalled on a few
not-so-important fixes for 3.8 due to the grumpy noise Linus made.
