5110e4de49 IB/ehca: Replace get_paca()->paca_index by the more portable raw_smp_processor_id()
We can use raw_smp_processor_id() here because the processor ID is
only used for debug output and therefore our use is preemption-unsafe.

51d2bfbddb IB/ehca: Move ehca2ib_return_code() out of line
ehca2ib_return_code() is not used in any fast path, and making it
non-inline saves ~1.5K of code.

a1a6ff1100 IB/ehca: Use common error code mapping instead of specific ones
Instead of one error mapping function for each potential error source
in ehca_mrmw.c, use a centralized function that handles all cases,
saving a three-figure line count.

28db6beb42 IB/ehca: Refactor sync between completions and destroy_cq using atomic_t
- ehca_cq.nr_events is made an atomic_t, eliminating a lot of locking.
- The CQ is removed from the CQ idr first now to make sure no more
  completions are scheduled on that CQ. The "wait for all completions to
  end" code becomes much simpler this way.

04d03bc576 IB/ehca: Fix eHCA driver compilation for uniprocessor
The eHCA driver does not compile for a uniprocessor configuration
(CONFIG_SMP=n), due to H_SUCCESS and other symbols being undefined.
This fixes it.
