drm/ttm: Don't evict BOs outside of the requested placement range
The radeon driver uses placement range restrictions for several reasons,
in particular to make sure BOs in VRAM can be accessed by the CPU, e.g.
during a page fault.
Without this change, TTM could evict other BOs while trying to satisfy
the requested placement, even if the evicted BOs were outside of the
requested placement range. Doing so didn't free up any space in the
requested placement range, so the (potentially high) eviction cost was
incurred for no benefit.
Nominating for stable because radeon driver changes in 3.17 made this
much more noticeable than before.

drm/mst: rework payload table allocation to conform better.
The old code has problems with the Dell MST monitors due to some
assumptions I made that weren't true.
I initially thought the Virtual Channel Payload IDs had to be in
the DPCD table in ascending order, however it appears that assumption
is bogus.
The old code also assumed it was possible to insert a member
into the table and it would move other members up, like it does
when you remove table entries, however reality has shown this
isn't true.
So the new code allocates VCPIs separate from entries in the payload
tracking table, and when we remove an entry from the DPCD table,
I shuffle the tracking payload entries around in the struct.
This appears to make VT switch more robust (still not perfect)
with an MST enabled Dell monitor.

The fence sequence should not be reset after creation, the old value is used instead.
On destruction the final value is written, to prevent another source of accidental
wraparound in case of a channel being destroyed after a hang, and unblocking any other
channel that may wait on the about-to-be-deleted channel to signal.
I'm nothing if not optimistic about any hope of recovery from that. ;-)

drm: Fixup locking for universal cursor planes
This here is actually one of the rare cases where lockdep hits a false
positive: The deadlock only happens in drm_fb_release, which cleans up
the file private structure when all the references are gone. So the
locking is the very last one and no one else can deadlock. It also
doesn't protect anything at all, since all ioctls are guaranteed to
have returned at this point - otherwise they'd still hold a reference
on the file.
So let's just drop it and replace it with a big comment.

drm: Fixup locking for universal cursor planes
Bunch of things amiss:
- Updating crtc->cursor_x/y was done without any locking. Spotted by
David Herrmann.
- Dereferencing crtc->cursor->fb was using the wrong lock, should take
the crtc lock.
- Grabbing _all_ modeset locks torpedoes the reason why we added
fine-grained locks originally: Cursor updates shouldn't stall on
background stuff like probing outputs.
Best is to just grab the crtc lock around everything and drop all the
other locking. The only issue is that we can't switch planes between
crtcs with that, so make sure that never happens when someone uses
universal plane helpers. This shouldn't be a possible regression ever
since legacy ioctls also only grabbed the crtc lock, so switching
crtcs was never possible for the underlying plane object. And i915
(the only user of universal cursors thus far) has fixed cursor->crtc
links.

drm: Don't update vblank timestamp when the counter didn't change
If we already have a timestamp for the current vblank counter, don't
update it with a new timestmap. Small errors can creep in between two
timestamp queries for the same vblank count, which could be confusing to
userspace when it queries the timestamp for the same vblank sequence
number twice.
This problem gets exposed when the vblank disable timer is not used
(or is set to expire quickly) and thus we can get multiple vblank
disable<->enable transition during the same frame which would all
attempt to update the timestamp with the latest estimate.

drm/ttm: Clean usage of ttm_io_prot() with TTM_PL_FLAG_CACHED
Today, most callers of ttm_io_prot() check TTM_PL_FLAG_CACHED before
calling it since on some archs it will unconditionally create non-cached
mappings.
But not all callers do which is incorrect as far as I can tell.
Instead, move that check inside ttm_io_port() itself for all archs
and make powerpc use the same implementation as ia64 and arm

Merge branch 'exynos-drm-next' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next
Sorry for late. This pull request includes some enhancements
for Exynos drm, new feature supports, cleanups and fixups
like below,
- Consider low power transmission for drm mipi dsi module,
and also add non-continuous clock mode support for Exynos
mipi dsi driver.
- Add Exynos3250 SoC support.
- Enhance and clean up ipp framework and fimc driver.
- Update to use component match support and fix up
de-initialization order.
- Remove a direct mmap interface and relevant stuff specific to
Exynos drm, use drm generic mmap interface instead.
And we will remove the specific interface from userspace
library, libdrm soon.
- Use universal plane which allows to replace fake primary plane
with the real one.
- Some code cleanups and fixups.

drm/exynos: switch to universal plane API
The patch replaces legacy functions
drm_plane_init() / drm_crtc_init() with
drm_universal_plane_init() and drm_crtc_init_with_planes().
It allows to replace fake primary plane with the real one.
Additionally the patch leaves cleanup of crtcs to core,
this way planes and crtcs are cleaned in correct order.

drm/exynos: use drm generic mmap interface
This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific
to Exynos drm and instead uses drm generic mmap.
We had used the interface specific to Exynos drm to do mmap directly,
not to use demand paging which maps each page with physical memory
at page fault handler. We don't need the specific mmap interface
because the drm generic mmap which uses vm offset manager stuff can
also do mmap directly.
This patch makes a userspace region to be mapped with whole physical
memory region allocated by userspace request when mmap system call is
requested.
Changelog v2:
- do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already
set by drm_gem_mmap
- do not include <linux/anon_inodes.h>, which isn't needed anymore.
