Stefan Roscher 1988d1fa1a IB/ehca: Remove unnecessary memory operations for userspace queue pairs
The queue map for flush completion circumvention is only used for
kernel space queue pairs.  This patch skips the allocation of the
queue maps in case the QP is created for userspace.  In addition, this
patch does not iomap the galpas for kernel usage if the queue pair is
only used in userspace.  These changes will improve the performance of
creation of userspace queue pairs.

Stefan Roscher 6f7bc01a73 IB/ehca: In case of lost interrupts, trigger EOI to reenable interrupts
During corner case testing, we noticed that some versions of ehca do
not properly transition to interrupt done in special load situations.
This can be resolved by periodically triggering EOI through H_EOI, if
EQEs are pending.

Joachim Fenkes 9a79fc0a1b IB/ehca: QP code restructuring in preparation for SRQ
- Replace init_qp_queues() by a shorter init_qp_queue(), eliminating
  duplicate code.

- hipz_h_alloc_resource_qp() doesn't need a pointer to struct ehca_qp any
  longer. All input and output data is transferred through the parms
  parameter.

- Change the interface to also support SRQ.

Joachim Fenkes c4ed790dfd IB/ehca: Implement modify_port
Add "Modify Port" verb support to eHCA driver.  The IB communication
manager needs this to set the IsCM port capability bit when
initializing.
