Message

This patch series replaces the page map carried in each memory region
with a struct xarray. It is based on a sketch developed by Jason
Gunthorpe. The first five patches are preparation that tries to
cleanly isolate all the mr specific code into rxe_mr.c. The sixth
patch is the actual change.

Bob Pearson (6):
  RDMA/rxe: Cleanup mr_check_range
  RDMA/rxe: Move rxe_map_mr_sg to rxe_mr.c
  RDMA-rxe: Isolate mr code from atomic_reply()
  RDMA-rxe: Isolate mr code from atomic_write_reply()
  RDMA/rxe: Cleanup page variables in rxe_mr.c
  RDMA/rxe: Replace rxe_map and rxe_phys_buf by xarray
