[PATCH hmm v3 00/14] Consolidate the mmu notifier interval_tree and locking
From: Jason Gunthorpe <jgg at mellanox.com>
8 of the mmu_notifier using drivers (i915_gem, radeon_mn, umem_odp, hfi1,
scif_dma, vhost, gntdev, hmm) drivers are using a common pattern where
they only use invalidate_range_start/end and immediately check the
invalidating range against some driver data structure to tell if the
driver is interested. Half of them use an interval_tree, the others

hmm_range_fault related fixes and legacy API removal v3
Hi Jérôme, Ben, Felxi and Jason,
below is a series against the hmm tree which cleans up various minor
bits and allows HMM_MIRROR to be built on all architectures.
