Merge branch 'mr_fix' into git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma for-next
Update mlx4 to support user MR creation against read-only memory, previously
it required the memory to be writable.
Based on rdma for-rc due to dependencies.
* mr_fix: (2 commits)
IB/mlx4: Mark user MR as writable if actual virtual memory is writable
IB/core: Make testing MR flags for writability a static inline function
