struct rdma_cm_id has member "struct work_struct net_work"
that is reused for enqueuing cma_netevent_work_handler()s
onto cma_wq.
Below crash[1] can occur if more than one call to
cma_netevent_callback() occurs in quick succession,
which further enqueues cma_netevent_work_handler()s for the
same rdma_... | ```diff

IBPB is expected to clear the RSB. However, if X86_BUG_IBPB_NO_RET is
set, that doesn't happen. Make indirect_branch_prediction_barrier()
take that into account by calling write_ibpb() which clears RSB on

First of all, using 'mmio' prevents proper implementation of 8-bit accessors.
Second, it's simply inconsistent with uart8250 set of options. Rename it to
