In theory, that function could release the lru lock between checking for bo on ddestroy list and a successful reserve if the bo was already reserved, and the function was called with waiting reserves allowed. However, all current reservers of a bo on the ddestroy list would atomically take the bo off the list after a successful reserve so this race should not have been hit, so no need to backport for stable. This patch also fixes a case found by Maarten Lankhorst where ttm_mem_evict_first called with no_wait_gpu would incorrectly spin waiting for bo idle if trying to evict a busy buffer that also sits on the ddestroy list.

The ttm_mem_evict_first function could theoretically drop the lru lock without retrying if a reservation from off the LRU list ended up waiting.

The drm_gem_cma_create() function never returns NULL but rather an error encoded in the return value using the ERR_PTR() macro. Callers therefore need to check for errors using the IS_ERR() macro. This change allows drivers to handle contiguous DMA allocation failures gracefully.

It's questionable use case, but weston/wayland already relies on this behaviour, and other drivers don't care about it, so it's a matter of compatibility.

Daniel writes: The big thing is the disabling of the hsw support by default, cc: stable. We've aimed for basic hsw support in 3.6, but due to a few bad happenstances we've screwed up and only 3.8 will have better modeset support than vesa. To avoid yet another round of fallout from such a gaffle on for the next platform we've added a module option to disable early hw support by default. That should also give us more flexibility in bring-up. Otherwise just small fixes: - 3 fixes from Egbert for sdvo corner cases - invert-brightness quirk entry from Egbert - revert a dp link training change, it regresses some setups - and shut up a spurious WARN in our gem fault handler. - regression fix for an oops on bit17 swizzling machines, introduce in 3.7 - another no-lvds quirk * 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel: drm/i915: Initialize obj->pages before use by i915_gem_object_do_bit17_swizzle() drm/i915: Add no-lvds quirk for Supermicro X7SPA-H drm/i915: Insert i915_preliminary_hw_support variable. drm/i915: shut up spurious WARN in the gtt fault handler Revert "drm/i915: Try harder to complete DP training pattern 1" DRM/i915: Restore sdvo_flags after dtd->mode->dtd Roundrtrip.

An interesting effect of using the generic version of linkage.h is that the padding is defined in terms of x86 NOPs, which can have even more interesting effects when the assembly code looks like this: ENTRY(func1) mov x0, xzr ENDPROC(func1) // fall through ENTRY(func2) mov x0, #1 ret ENDPROC(func2) Admittedly, the code is not very nice. But having code from another architecture doesn't look completely sane either. The fix is to add arm64's version of linkage.h, which causes the insertion of proper AArch64 NOPs.

Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: * The python binding needs to link with libtraceevent and to initialize the 'page_size' variable so that mmaping works again. * The callchain folding character that appears on the TUI just before the overhead had disappeared due to recent changes, add it back. * Intel PEBS in VT-x context uses the DS address as a guest linear address, even though its programmed by the host as a host linear address. This either results in guest memory corruption and or the hardware faulting and 'crashing' the virtual machine. Therefore we have to disable PEBS on VT-x enter and re-enable on VT-x exit, enforcing a strict exclude_guest. Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern. * Fix build on sparc due to UAPI, fix from David Miller. * Fixes for the srclike sort key for unresolved symbols and when processing samples in JITted code, where we don't have an ELF file, just an special symbol table, fixes from Namhyung Kim. * Fix some leaks in libtraceevent, from Steven Rostedt.

Emit the magic string that indicates a module has a signature after the signature data instead of before it. This allows module_sig_check() to be made simpler and faster by the elimination of the search for the magic string. Instead we just need to do a single memcmp(). This works because at the end of the signature data there is the fixed-length signature information block. This block then falls immediately prior to the magic number. From the contents of the information block, it is trivial to calculate the size of the signature data and thus the size of the actual module data.

/proc/<pid>/numa_maps scans vma and show mempolicy under mmap_sem. It sometimes accesses task->mempolicy which can be freed without mmap_sem and numa_maps can show some garbage while scanning. This patch tries to take reference count of task->mempolicy at reading numa_maps before calling get_vma_policy(). By this, task->mempolicy will not be freed until numa_maps reaches its end. V2->v3 - updated comments to be more verbose. - removed task_lock() in numa_maps code. V1->V2 - access task->mempolicy only once and remember it. Becase kernel/exit.c can overwrite it.
