To be more specific, here's what I did:
1. apply kernel module patch - re-insert module
1. QEMU does: ibv_reg_mr(........IBV_ACCESS_GIFT | IBV_ACCESS_REMOTE_READ)
2. Start the RDMA migration
3. Migration completes without any errors
This test does *not* work with a cgroup swap limit, however. The process
gets killed. (Both with and without GIFT)

Not sure I'm interpreting this correctly. Are you saying that things
worked without actually setting the GIFT flag? In which case why are
we adding this flag?
