drm/tegra: Changes for v3.14-rc1 (update)
These patches fix some issues caused by the DRM panel support from the
previous pull request and add two more panels (for the Toshiba AC100 as
well as the Seaboard and Ventana).

Here's the vblank timestamp pull request you wanted.
I addressed the few bugs that Mario pointed out and added
the r-bs.
As it has been a while since I made the changes, I gave it a
quick spin on a few different i915 machines. Fortunately
everything still seems to be fine.

Using s64 for the timestamping constants is wasteful. Signed 32bit
integers get us a range of over +-2 seconds. Presuming that no-one
wants to a vrefresh rate less than 0.5, we can switch to using int
for the timestamping constants. We save a few bytes in drm_crtc and
avoid a bunch of 64bit math.

Rather than using crtc->hwmode, just pass the relevant mode to
drm_calc_vbltimestamp_from_scanoutpos(). This removes the last hwmode
usage from core drm.

We don't really use hwmode anymore in i915, so eliminating its use
from the core code seems prudent. Just pass the appropriate mode
to drm_calc_timestamping_constants().

drm-intel-next-2014-01-10:
- final bits for runtime D3 on Haswell from Paul (now enabled fully)
- parse the backlight modulation freq information in the VBT from Jani
(but not yet used)
- more watermark improvements from Ville for ilk-ivb and bdw
- bugfixes for fastboot from Jesse

Note that the pull request includes a backmerge of the last drm-fixes
pulled into Linus' tree - things where getting a bit too messy. So the
shortlog also contains a bunch of patches from Linus tree. Please yell if
you want me to frob it for you a bit.

Using the new drm_crtc_mask() function, drm_encoder_crtc_ok() can now be
written in a significantly shorter way, so it can be moved to a header
file and be made static inline.

The encoder possible_crtcs mask identifies which CRTCs can be bound to
a particular encoder. Each bit from bit 0 defines an index in the list
of CRTCs held in the DRM mode_config crtc_list. Rather than having
drivers trying to track the position of their CRTCs in the list, expose
the code which already exists for calculating the appropriate mask bit
for a CRTC.

This was hidden in a generic void * dev->mm_private. But only ever
used for gem. But thanks to this fake generic pretension no one
noticed that Rob's drm drivers are now all broken.
So just give the offset manager a type pointer and fix up msm, omapdrm
and tilcdc.

Anyway, nothing big here, Three more code cleanup patches from Rashika
Kheria, and one TTM/vmwgfx patch from me that tightens security around TTM
objects enough for them to opened using prime objects from render nodes:
Previously any client could access a shared buffer using the "name", also
without actually opening it. Now a reference is required, and for render nodes
such a reference is intended to only be obtainable using a prime fd.

drm/ttm: ttm object security fixes for render nodes
When a client looks up a ttm object, don't look it up through the device hash
table, but rather from the file hash table. That makes sure that the client
has indeed put a reference on the object, or in gem terms, has opened
the object; either using prime or using the global "name".
To avoid a performance loss, make sure the file hash table entries can be
looked up from under an RCU lock, and as a consequence, replace the rwlock
with a spinlock, since we never need to take it in read mode only anymore.
Finally add a ttm object lookup function for the device hash table, that is
intended to be used when we put a ref object on a base object or, in gem terms,
when we open the object.

drm/tegra: Changes for v3.14-rc1
This series of changes brings DRM panel support as well as initial code
to register DSI hosts and peripherals and bind them to DSI drivers. The
panel and DSI code are both used by the simple panel driver.
The Tegra-specific changes build on top of this work to add support for
various panels found on Tegra boards. New drivers enable the DSI host
found on Tegra114 and a special hardware block that calibrates the pads
used for DSI and CSI. The host1x and the display controller drivers gain
basic Tegra124 support. To round of the new features, the DRM driver now
sports a very simple PRIME implementation.
In addition there are various improvements such as the host1x API being
exported so that client drivers (like the Tegra DRM driver) can be built
as modules. HDMI now does better power management and legacy FBDEV can
now be disabled via Kconfig (though it's still enabled by default). A
few sparse warnings have been squashed and various parts of the code
have become more robust.

This is just used for a debugfs file, and we can easily reconstruct
this number by just walking the list twice. Which isn't really bad for
a debugfs file anyway.
So let's rip this out.
There's the other issue that the dev->vmalist itself is a bit useless,
since that can be reconstructed with all the memory mapping
information from proc. But remove that is a different topic entirely.

It's racy, and it's only used in debugfs. There are simpler ways to
know whether something is going on (like looking at dmesg with full
debugging enabled). And they're all much more useful.

Now dev->ioctl_count tries to prevent the device from disappearing if
it's still in use. And if we'd actually need this code it would be
hopelessly racy and broken.
But luckily the vfs already takes care of this. So we can just rip it
out.
