677033b5c9 drm/amdkfd: Prevent user space using both svm and kfd api to register same user buffer 
When xnack is on user space can use svm page restore to set a vm range without
setup it first, then use regular api to register. Currently kfd api and svm are
not interoperable. We already have check on that, but for user buffer the mapping
address is not same as buffer cpu virtual address. Add checking on that to
avoid error propagate to hmm.

0eb15a47bf selftests/user_events: add a note about user_events.h dependency 
This test depends on <linux/user_events.h> exported in uapi
The following commit removed user_events.h out of uapi:
commit 5cfff569ca ("tracing: Move user_events.h temporarily out
   of include/uapi")

This test will not compile until user_events.h is added back to uapi.

b0bbd86a28 dm sysfs: make kobj_type structure constant 
Since commit ee6d3dd4ed ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.

Take advantage of this to constify the structure definition to prevent
modification at runtime.

0b22ff5360 dm: remove flush_scheduled_work() during local_exit() 
Commit acfe0ad74d ("dm: allocate a special workqueue for deferred
device removal") switched from using system workqueue to a single
workqueue local to DM.  But it didn't eliminate the call to
flush_scheduled_work() that was introduced purely for the benefit of
deferred device removal with commit 2c140a246d ("dm: allow remove to
be deferred").

Since DM core uses its own workqueue (and queue_work) there is no need
to call flush_scheduled_work() from local_exit().  local_exit()'s
destroy_workqueue(deferred_remove_workqueue) handles flushing work
started with queue_work().
