IB/qib: Eliminate 64-bit jiffies use
...
The qib driver makes use of the the 64-bit jiffies API.
Code inspection reveals that that version of the API is not really
required. This patch converts to use the "normal" jiffies.

IB/uverbs: Protect QP multicast list
...
Userspace verbs multicast attach/detach operations on a QP are done
while holding the rwsem of the QP for reading. That's not sufficient
since a reader lock allows more than one reader to acquire the
lock. However, multicast attach/detach does list manipulation that
can corrupt the list if multiple threads run in parallel.
Fix this by acquiring the rwsem as a writer to serialize attach/detach
operations. Add idr_write_qp() and put_qp_write() to encapsulate
this.
This fixes oops seen when running applications that perform multicast
joins/leaves.
