0cb4fe8d26 IB/uverbs: Don't leak ref to mm on error path 
In ib_umem_release_on_close(), if the kmalloc() fails, then a
reference to current->mm will be leaked.  Fix this by adding a mmput()
instead of just returning on kmalloc() failure.

eb8ffbfed5 [PATCH] IB uverbs: memory pinning implementation 
Add support for pinning userspace memory regions and returning a list of pages
in the region.  This includes tracking pinned memory against vm_locked and
preventing unprivileged users from exceeding RLIMIT_MEMLOCK.
