  Hello,

Now when the usage of get_user_pages() in media drivers got cleaned up, here
comes a series which removes knowledge about mmap_sem from a couple of other
drivers. Patches are trivial and standalone but please check, they are only
compile tested. If you are OK with them, either take them through your
respective trees or ack them and I can take care of pushing them to Linus
(probably through mm tree). Thanks.

After these patches there are some 12 call sites of get_user_pages() outside of
core code (mostly infiniband and RDMA). So we are slowly getting to the goal of
removing knowledge about page fault locking from drivers which will
consequently allow us to change the locking rules with reasonable effort.
