From: Rob Clark <robdclark@xxxxxxxxxxxx>
The first six paches are various cleanups and simplifications. The
next two get rid of redundant vma lookups in the submit and retire
paths. Following that, fenced vma lets us indicate a fence value
following which the vma is no longer used, which is needed because
otherwise userspace could observe the signaled fence prior to
retire_submits() finishing. (With userspace allocated GPU addresses
userspace is tracking when a buffer is no longer used and it's vma can
be deleted.) And finally the last patch adds the new uabi for user-
space allocated iova.
v2: Fix inuse check in last patch, split GEM_WARN_ON() conversion to
separate patch, and nits
