Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch.  This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.

Conflicts:
	drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f
	(IB/mlx5: Fix cleanup order on unload) added to for-rc and
	commit b5ca15ad (IB/mlx5: Add proper representors support)
	add as part of the devel cycle both needed to modify the
	init/de-init functions used by mlx5.  To support the new
	representors, the new functions added by the cleanup patch
	needed to be made non-static, and the init/de-init list
	added by the representors patch needed to be modified to
	match the init/de-init list changes made by the cleanup
	patch.
Updates:
	drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
	prototypes added by representors patch to reflect new function
	names as changed by cleanup patch
	drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
	stage list to match new order from cleanup patch
