	Resurrecting the stuff from last cycle.
Context: several places in drm have racy uses of close_fd().
Not hard to fix, thankfully.

	Changed since the last posting: as requested, KFD
fix had been split in two commits - introduction of helper
(drm_gem_prime_handle_to_dmabuf()) and switching kfd_mem_export_dmabuf()
to that.

	Branch in git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git #for-drm,
individual patches in followups.

	Please, review; IMO that ought to go through drm and amd-gfx
trees.
