into drm-next drm/tegra: Changes for v3.13-rc1 The biggest part of the changes is the decoupling of the host1x and DRM drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra from whence it came. There is a lot of cleanup as well, and the drivers can now be properly unloaded and reloaded. HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen. gr2d support was extended to Tegra114 and the gr3d driver that has been in the works for quite some time finally made it in. All pieces to run an OpenGL driver on top of an upstream kernel are now available. Support for syncpoint bases was added by Arto Merilainen. This is useful for synchronizing between command streams from different engines such as gr2d and gr3d. Erik Faye-Lund and Wei Yongjun contributed various small fixes.

Negative message lengths make no sense -- so don't do negative queue lenghts or identifier counts. Prevent them from getting negative. Also change the underlying data types to be unsigned to avoid hairy surprises with sign extensions in cases where those variables get evaluated in unsigned expressions with bigger data types, e.g size_t. In case a user still wants to have "unlimited" sizes she could just use INT_MAX instead.

2013-11-02ARC: Incorrect mm reference used in vmalloc fault handlerVineet Gupta
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 pre-userland code path - it was introduced with commit 20bafb3d23d108bc "n_tty: Move buffers into n_tty_data" Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Gilad Ben-Yossef <gilad@benyossef.com> Cc: Noam Camus <noamc@ezchip.com> Cc: stable@vger.kernel.org #3.10 and 3.11 Cc: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2013-11-01memcg: remove incorrect underflow checkGreg Thelen
When a memcg is deleted mem_cgroup_reparent_charges() moves charged memory to the parent memcg. As of v3.11-9444-g3ea67d0 "memcg: add per cgroup writeback pages accounting" there's bad pointer read. The goal was to check for counter underflow. The counter is a per cpu counter and there are two problems with the code: (1) per cpu access function isn't used, instead a naked pointer is used which easily causes oops. (2) the check doesn't sum all cpus Test: $ cd /sys/fs/cgroup/memory $ mkdir x $ echo 3 > /proc/sys/vm/drop_caches $ (echo $BASHPID >> x/tasks && exec cat) & [1] 7154 $ grep ^mapped x/memory.stat mapped_file 53248 $ echo 7154 > tasks $ rmdir x <OOPS> The fix is to remove the check. It's currently dangerous and isn't worth fixing it to use something expensive, such as percpu_counter_sum(), for each reparented page. __this_cpu_read() isn't enough to fix this because there's no guarantees of the current cpus count. The only guarantees is that the sum of all per-cpu counter is >= nr_pages.

Even though we only check for unclaimed registers while we're writing registers, if we read a bad register we'll still trigger a CPU error interrupt, and we'll print an "Unclaimed register" DRM_ERROR due to that. To avoid this error, just avoid touching power domains that are not enabled. Use kzalloc so we're sure all the disabled domains will be zeroed on the error state file. We already print the information that is enough to discover if the power well is enabled on the error state file, so this should not be a problem.

2013-11-01drm/i916: add "auto" pipe CRC sourceDaniel Vetter
On gmch platforms the normal pipe source CRC registers don't work for DP and TV encoders. And on newer platforms the single pipe CRC has been replaced by a set of CRC at different stages in the platform. Now most of our userspace tests don't care one bit about the exact CRC, they simply want something that reflects any changes on the screen. Hence add a new auto target for platform agnostic tests to use. v2: Pass back the adjusted source so that it can be shown in debugfs. v3: I seem to be unable to get a stable CRC for DP ports. So let's just disable them for now when using the auto mode. Note that testcases need to be restructured so that they can dynamically skip connectors. They also first need to set up the desired mode configuration, since otherwise the auto mode won't do the right thing. v4: Don't leak the modeset mutex on error paths. v5: Spelling fix for the i9xx auto_source function.

Seems to be stable on them and improves peformance as most SI asics have very low boot clocks. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-11-01drm/radeon: enable DPM by default on SUMO/PALM APUsAlex Deucher
DPM seems to be stable on these asics and it drastically improves performance depending on the boot clocks. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-11-01drm/radeon/dpm: only print dpm debugging messages when radeon_dpm=1Alex Deucher

2013-11-01drm/radeon: Implement radeon_pci_shutdownMarkus Trippelsdorf
