If we want to map GPU memory into user-space, we need to linearize the addresses to not confuse mm-core. Currently, GEM and TTM both implement their own offset-managers to assign a pgoff to each object for user-space CPU access. GEM uses a hash-table, TTM uses an rbtree. This patch provides a unified implementation that can be used to replace both. TTM allows partial mmaps with a given offset, so we cannot use hashtables as the start address may not be known at mmap time. Hence, we use the rbtree-implementation of TTM. We could easily update drm_mm to use an rbtree instead of a linked list for it's object list and thus drop the rbtree from the vma-manager. However, this would slow down drm_mm object allocation for all other use-cases (rbtree insertion) and add another 4-8 bytes to each mm node. Hence, use the separate tree but allow for later migration. This is a rewrite of the 2012-proposal by David Airlie <airlied@linux.ie> v2: - fix Docbook integration - drop drm_mm_node_linked() and use drm_mm_node_allocated() - remove unjustified likely/unlikely usage (but keep for rbtree paths) - remove BUG_ON() as drm_mm already does that - clarify page-based vs. byte-based addresses - use drm_vma_node_reset() for initialization, too v4: - allow external locking via drm_vma_offset_un/lock_lookup() - add locked lookup helper drm_vma_offset_lookup_locked() v5: - fix drm_vma_offset_lookup() to correctly validate range-mismatches (fix (offset > start + pages)) - fix drm_vma_offset_exact_lookup() to actually do what it says - remove redundant vm_pages member (add drm_vma_node_size() helper) - remove unneeded goto - fix documentation Signed-off-by: NDavid Herrmann <dh.herrmann@gmail.com> Reviewed-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: NDave Airlie <airlied@gmail.com>

drm_gem_object_init() and drm_gem_private_object_init() do exactly the same (except for shmem alloc) so make the first use the latter to reduce code duplication. Also drop the return code from drm_gem_private_object_init(). It seems unlikely that we will extend it any time soon so no reason to keep it around. This simplifies code paths in drivers, too. Last but not least, fix gma500 to call drm_gem_object_release() before freeing objects that were allocated via drm_gem_private_object_init(). That isn't actually necessary for now, but might be in the future.

They aren't really bugfixes, but a bunch of new helper macros for drivers to properly create attribute groups, which drivers and subsystems need to fix up a ton of race issues with incorrectly creating sysfs files (binary and normal) after userspace has been told that the device is present. Also here is the ability to create binary files as attribute groups, to solve that race condition, which was impossible to do before this, so that's my fault the drivers were broken. The majority of the .c changes is indenting and moving code around a bit. It affects no existing code, but allows the large backlog of 70+ patches that I already have created to start flowing into the different subtrees, instead of having to live in my driver-core tree, causing merge nightmares in linux-next for the next few months.

Recent change to use bio_copy_data() in raid1 when repairing an array is faulty. The underlying may have changed the bio in various ways using bio_advance and these need to be undone not just for the 'sbio' which is being copied to, but also the 'pbio' (primary) which is being copied from. So perform the reset on all bios that were read from and do it early. This also ensure that the sbio->bi_io_vec[j].bv_len passed to memcmp is correct. This fixes a crash during a 'check' of a RAID1 array. The crash was introduced in 3.10 so this is suitable for 3.10-stable.

commit 7ceb17e8 md: Allow devices to be re-added to a read-only array. allowed a bit more than just that. It also allows devices to be added to a read-write array and to end up skipping recovery. This patch removes the offending piece of code pending a rewrite for a subsequent release. More specifically: If the array has a bitmap, then the device will still need a bitmap based resync ('saved_raid_disk' is set under different conditions is a bitmap is present). If the array doesn't have a bitmap, then this is correct as long as nothing has been written to the array since the metadata was checked by ->validate_super. However there is no locking to ensure that there was no write. Bug was introduced in 3.10 and causes data corruption so patch is suitable for 3.10-stable.

1/ When an different between blocks is found, data is copied from one bio to the other. However bv_len is used as the length to copy and this could be zero. So use r10_bio->sectors to calculate length instead. Using bv_len was probably always a bit dubious, but the introduction of bio_advance made it much more likely to be a problem. 2/ When preparing some blocks for sync, we don't set BIO_UPTODATE except on bios that we schedule for a read. This ensures that missing/failed devices don't confuse the loop at the top of sync_request write. Commit 8be185f2 "raid10: Use bio_reset()" removed a loop which set BIO_UPTDATE on all appropriate bios. So we need to re-add that flag. These bugs were introduced in 3.10, so this patch is suitable for 3.10-stable, and can remove a potential for data corruption.
