wow no idea how I got this far without seeing this, leaking the entries in the list makes kmalloc-64 slab grow.

Copy/Paste typo.. we need to test for ->kdev instead of ->dev. Reported-by: Juha Leppänen <juha_efku@dnainternet.net> Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
airlied: The lifetime changes introduced in 5bdebb183c9702a8c57a01dff09337be3de337a6 tried to use device_create, however that led to the regression where dev->type wasn't getting set correctly. First attempt at fixing it would have led to a race, so this undoes the device_createa work and does it all manually making sure the dev->type is setup before we register the device.

This patch releases a vma object when cleaning up userptr resources. A new vma object was allocated and copied when getting userptr pages so the new vma object should be freed properly if the userptr pages aren't used anymore.

The set_need_resched() removal fix and yet another fix in ttm_bo_move_memcpy(). * 'ttm-fixes-3.13' of git://people.freedesktop.org/~thomash/linux: drm/ttm: Remove set_need_resched from the ttm fault handler drm/ttm: Don't move non-existing data

Just a small pile of fixes for bugs and a few regressions. I'm still trying to track down a driver load hang on my g33 (which infuriatingly doesn't happen when loading the module manually after boot), somehow bisecting loves to go astray on this one :( And there's a (harmless) locking WARN in the suspend code due to one of Jesse's vlv backlight rework patches. Otherwise nothing outstanding afaik. * tag 'drm-intel-fixes-2013-11-20' of git://people.freedesktop.org/~danvet/drm-intel: drm/i915: Fix gen3 self-refresh watermarks drm/i915: Replicate BIOS eDP bpp clamping hack for hsw drm/i915: Do not enable package C8 on unsupported hardware drm/i915: Hold pc8 lock around toggling pc8.gpu_idle drm/i915: encoder->get_config is no longer optional drm/i915/tv: add ->get_config callback drm/i915: restore the early forcewake cleanup Partially revert "drm/i915: tune the RC6 threshold for stability" drm/i915: flush cursors harder i915: Use 120MHz LVDS SSC clock for gen5/gen6/gen7 x86/early quirk: use gen6 stolen detection for VLV drm/i915/dp: set sink to power down mode on dp disable
More fixes for radeon. This adds new queries for tiling on CIK, and fixes a crash in handling acpi atif backlight events on CIK. Some fixes for radeon for 3.13. Mostly CI stability fixes. I think I've tracked down the stability problems with dpm on Trinity/Richland, so I'm going to enable that by default now. * 'drm-next-3.13' of git://people.freedesktop.org/~agd5f/linux: drm/radeon: hook up backlight functions for CI and KV family. drm/radeon/cik: Add macrotile mode array query drm/radeon/cik: Return backend map information to userspace drm/radeon: enable DPM by default in TN asics drm/radeon: adjust TN dpm parameters for stability (v2) drm/radeon: use a single doorbell for cik kms compute drm/radeon/vm: don't attempt to update ptes if ib allocation fails drm/radeon: disable CIK CP semaphores for now drm/radeon: allow semaphore emission to fail drm/radeon: add semaphore trace point radeon: workaround pinning failure on low ram gpu radeon/i2c: do not count reg index in number of i2c byte we are writing. drm/radeon: cypress_dpm: Fix unused variable warning when CONFIG_ACPI=n drm: radeon: ni_dpm: Fix unused variable warning when CONFIG_ACPI=n
