883a99c702 [IB] uverbs: Add a mask of device methods allowed for userspace 
Give each device a uverbs_cmd_mask, so that a low-level driver can
control which methods may be called on behalf of userspace.

63c47c286d [IB] uverbs: Close some exploitable races 
Al Viro pointed out that the current IB userspace verbs interface
allows userspace to cause mischief by closing file descriptors before
we're ready, or issuing the same command twice at the same time.  This
patch closes those races, and fixes other obvious problems such as a
module reference leak.

Some other interface bogosities will require an ABI change to fix
properly, so I'm deferring those fixes until 2.6.15.

a4d61e8480 [PATCH] IB: move include files to include/rdma 
Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.
