2012-10-16drm/nouveau/pm: do not stop reclocking if failing to set the fan speedMartin Peres
With the introduction of fan management modes, fan may not be drivable. We should allow reclocking nonetheless. This return was stupid to begin with since it may have left the card in an intermediate state (clocks corresponding to a perflvl and voltage corresponding to another one). The reclocking code will need to be rewritten in a near-future in order to provide a better error handling.

2012-10-15drm/radeon: Don't destroy I2C Bus Rec in radeon_ext_tmds_enc_destroy().Egbert Eich
radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[] to destroy each of them. radeon_ext_tmds_enc_destroy() however also has code to destroy it's associated I2C bus rec which has been obtained by radeon_i2c_lookup() and is therefore also in the i2c_bus[] list. This causes a double free resulting in a kernel panic when unloading the radeon driver.

2012-10-15drm/radeon: allocate page tables on demand v4Christian König
Based on Dmitries work, but splitting the code into page directory and page table handling makes it far more readable and (hopefully) more reliable. Allocations of page tables are made from the SA on demand, that should still work fine since all page tables are of the same size. Also using the fact that allocations from the SA are mostly continuously (except for end of buffer wraps and under very high memory pressure) to group updates send to the chipset specific code into larger chunks. v3: mostly a rewrite of Dmitries previous patch. v4: fix some typos and coding style Signed-off-by: Dmitry Cherkasov <Dmitrii.Cherkasov@amd.com> Signed-off-by: Christian König <deathsimple@vodafone.de> Tested-by: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

We need to check whether the _other plane is on our pipe, not whether our plane is on the other pipe.

Noticed by Chris Wilson. v3: I've checked Bspec, and the flexible plane->pipe mapping is a gen2/3 feature, so test for that instead of PCH_SPLIT v4: Check whether we indeed have 2 pipes before checking the other pipe, to avoid upsetting i845g/i865g.

2012-10-12drm/i915: rip out the pipe A quirk for i855gmDaniel Vetter
This seems to be the root-cause that breaks resume on my i855gm when I apply the "drm/i915: fixup the plane->pipe fixup code" patch. And that code doesn't even run on my machine, so it's pure timing changes causing the regression. Furthermore resume has been constantly switching between working and broken on this machine ever since kms support has been merged, seemingly with no related change as a root cause. And always with the same symptoms of the backlight lighting up, but the lvds panel only displaying black. Also, of both i855gm variants only one is in the table. And in the past we've only ever removed entries from this quirk table because it breaks things. So let's just remove it - in case there's indeed a bios out there relying on a running pipe A, we can add back in a more precise quirk entry, like all the others (save for i830/i845).

2012-10-12drm/i915: Disallow preallocation of requestsChris Wilson
The intention was to allow the caller to avoid a failure to queue a request having already written commands to the ring. However, this is a moot point as the i915_add_request() can fail for other reasons than a mere allocation failure and those failure cases are more likely than ENOMEM. So the overlay code already had to handle i915_add_request() failures, and due to commit 3bb73aba1ed5198a2c1dfaac4f3c95459930d84a Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Jul 20 12:40:59 2012 +0100 drm/i915: Allow late allocation of request for i915_add_request() the error handling code in intel_overlay.c was subject to causing double-frees, as found by coverity.

into fbdev-next Omapdss driver changes for the 3.7 merge window. Notable changes: * Basic writeback support for DISPC level. Writeback is not yet usable, though, as we need higher level code to actually expose the writeback feature to userspace. * Rewriting the omapdss output drivers. We're trying to remove the hard links between the omapdss and the panels, and this rewrite work moves us closer to that goal. * Cleanup and restructuring patches that have been made while working on device tree support for omapdss. Device tree support is still some way ahead, but these patches are good cleanups in themselves. * Basic OMAP5 DSS support for DPI and DSI outputs. * Workaround for the problem that GFX overlay's fifo is too small for high resolution scenarios, causing underflows. * Cleanups that remove dependencies to omap platform code.
2012-10-09mm: kill vma flag VM_RESERVED and mm->reserved_vm counterKonstantin Khlebnikov

The check is to verify that no batches were submitted to the kernel whilst the UMS/GEM client was suspended - to which the BUG_ONs are a crude approximation. Furthermore, the checks are too late, since it means we attempted to program the hardware whilst it was in an invalid state, the BUG_ONs are the least of your concerns at that point."

exynos-drm-hdmi need context pointers from hdmi and mixer. These pointers were expected from the plf data. Cleaned this dependency by exporting i/f which are called by hdmi, mixer driver probes for setting their context.
