5d7edb3c1a [IB] Add idr_destroy() calls on module unload
Add idr_destroy() calls to the module_exit() functions of the four IB
driver modules that use idrs, so we don't leak idr_layer_cache objects
when these modules are unloaded.

0b2b35f681 [PATCH] IB: Add user-supplied context to userspace CM ABI
- Add user specified context to all uCM events.  Users will not retrieve
  any events associated with the context after destroying the corresponding
  cm_id.
- Provide the ib_cm_init_qp_attr() call to userspace clients of the CM.
  This call may be used to set QP attributes properly before modifying the QP.
- Fixes some error handling synchonization and cleanup issues.
- Performs some minor code cleanup.

b9ef520f9c [PATCH] IB: fix userspace CM deadlock
Fix deadlock condition resulting from trying to destroy a cm_id
from the context of a CM thread.  The synchronization around the
ucm context structure is simplified as a result, and some simple
code cleanup is included.
