If the number of items to process in the request is zero, we can forgo
duplicating, sorting the request and feeding it into the kernel and
instead report success immediately. This prevents a NULL dereference of
the sorted->items for the no-op request.

In case of YF/YS tiled buffers libdrm need not know about the tiling
format because these buffers don't have hardware support to be tiled
or detiled through a fenced region. But, libdrm still need to know
about buffer alignment restrictions because kernel uses it when
resolving the relocation.
Mesa uses drm_intel_gem_bo_alloc_for_render() to allocate Yf/Ys buffers.
So, use the passed alignment value in this function to initialize the
align variable in drm_intel_bo. Note that we continue ignoring the
alignment value passed to drm_intel_gem_bo_alloc() to follow the
previous behavior.
V2: Add a condition to avoid allocation from cache. (Ben)
V3: Make no changes in cache allocation strategy. Just update the alignment.
Update the aperture size estimate including the alignment. (Ben, Chris)
V4: Move aperture size adjustments inside drm_intel_bo_gem_set_in_aperture_size()

Also remove the silent mapping to G2D_IMGBUF_GEM when an

have a bug in the code.

This reverts commit fde4969176.
The commit adds an API that does not seem flexible enough to be used in
current open-source projects. Additionally it adds a hidden dependency
of libudev, which when used in mesa caused grief when combined with
Steam('s runtime).
Let's revert this for now and add a tweaked API later on that can be
used in mesa/xserver.

In order to use userptr, the kernel tracks the owner's mm with a
mmu_notifier. Setting that is very expensive - it involves taking all
mm_locks and a stop_machine(). This tracking lives only for as long as
the client is using userptr objects - so if the client allocates then
frees a userptr in a loop, we will be executing that heavyweight setup
everytime. To ammoritize this cost, just leak the test bo and the single
backing page we use for detecting userptr.
