Linus, please pull from

master.kernel.org:/pub/scm/linux/kernel/git/roland/infiniband.git for-linus

This tree is also available from kernel.org mirrors at:

git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git for-linus

This is mostly (by total lines of patch) cleanups for the ipath driver,
with a few other fixes thrown in.

The exact changes and patch are:

Adrian Bunk:
IB/mthca: make a function static

Hal Rosenstock:
IB/mad: Fix RMPP version check during agent registration

Roland Dreier:
IB/srp: Remove request from list when SCSI abort succeeds
IB/ipath: Make more names static
IB/ipath: Fix whitespace
