a) I thought using the same subject line was the convention since
   it is essentially one patch.  I split it due to size and the
   fact that each patch has a different owner.
b) This is the format "svn diff" produces. I haven't had any
   complaints with it bwfore.  I can resend them if you want.

The bulk of the changes are to the InfiniPath kernel driver (ib_ipath)
to support mmap'ing the CQ and receive queues (QP, SRQ) into
the user level verbs library.
The changes to the core IB were neccessary in order to allow
additional information (i.e., the mmap offset) to be returned
from the kernel driver to the user level verbs driver plugin.
