This series from Pat & Brendan reworks the system memory pinning in our driver
to better handle different types of memory buffers that are passed into.

Patrick Kelsey (3):
IB/hfi1: Fix math bugs in hfi1_can_pin_pages()
IB/hfi1: Fix sdma.h tx->num_descs off-by-one errors
IB/hfi1: Do all memory-pinning through hfi1's pinning interface
