This series adds basic self tests for HMM and are intended for Jason
Gunthorpe's rdma tree which has a number of HMM patches applied.

Changes v7 -> v8:
Rebased to Jason's rdma/hmm tree, plus Jason's 6 patch series
   "Small hmm_range_fault() cleanups".
Applied a number of changes from Jason's comments.

Changes v6 -> v7:
Rebased to linux-5.6.0-rc6
Reverted back to just using mmu_interval_notifier_insert() and making
   this series only introduce HMM self tests.

Changes v5 -> v6:
Rebased to linux-5.5.0-rc6
Refactored mmu interval notifier patches
Converted nouveau to use the new mmu interval notifier API

Changes v4 -> v5:
Added mmu interval notifier insert/remove/update callable from the
   invalidate() callback

Isn't UAPI folder supposed to be for user-visible interfaces that follow
the rule of non-breaking user space and not for selftests?

Thanks

Most of the other kernel module tests seem to invoke the test as part of the
module load/init. I'm open to moving it if there is a more appropriate location.
