[for-rc,0/3] Fixes for 64K page size support

This is a three patch series.

The first core hunk corrects the core iterator to use __sg_advance to skip
preceding 4k HCA pages.

The second patch corrects an iWarp issue where the SQ must be PAGE_SIZE
aligned.

The third patch corrects an issue with the RDMA driver use of
ib_umem_find_best_pgsz(). QP and CQ allocations pass PAGE_SIZE as the
only bitmap bit. This is incorrect and should use the precise 4k value.

Mike Marciniszyn (3):
  RDMA/core: Fix umem iterator when PAGE_SIZE is greater then HCA pgsz
  RDMA/irdma: Ensure iWarp QP queue memory is OS paged aligned
  RDMA/irdma: Fix support for 64k pages
