[v4,for-next,0/7] rdma_rxe: add memory windows to rxe

Message

Bob Pearson Sept. 3, 2020, 10:40 p.m. UTC

This set of patches adds support to rdma_rxe for:

	alloc_mw (type 1 and 2)
	dealloc_mw
	bind_mw as a user API (type 1)
	bind_mw as a local send queue operationa (type 2)
	invalidate mw as a local send queue operation
	invalidate mw as a remote send operation
	memory access to bound MRs via MWs with VA or ZB MWs

Changes in this version from the previous version:

	Dropped patches that have already been picked up in for-next
	rearranged the order to be more logical and avoid throw away
	code in stubs.
	This work is focused on MWs. There are some areas
	exposed in the existing driver that should be improved
	but that can be done later.
