IB/rdmavt: Add misc dev register functionality

There are a number of minor things that should be set by rdmavt rather
than by the drivers. Now that rdmavt has solidified in its design we can

IB/rdmavt: Support creating qps with GFP_NOIO flag

The current code is problematic when the QP creation and ipoib is

In that case, the GFP_KERNEL allocation within create_qp causes

This fix adds support to create queue pair with GFP_NOIO flag for

This was previously fixed in qib but needed to get ported to hfi1.

invalidation has occurred and needs a matching command code that
will be used to read the invalidated TIDs.

Add the event bit and the new command to the exported header file.

The command is also added to the switch() statement in file_ops.c
for completeness and in preparation for its usage later.

uapi/hfi1_user: Correct comment for capability bit

The HFI1_CAP_TID_UNMAP comment was incorrectly implying the
opposite of what capability actually did. Correct this error.

staging/hfi1: Add function stubs for TID caching

Add mmu notify helper functions and TID caching function
stubs in preparation for the TID caching implementation.

TID caching makes use of the MMU notifier to allow the driver
to respond to the user freeing memory which is allocated to
the HFI.

This patch implements the basic MMU notifier functions to insert,
find and remove buffer pages from memory based on the mmu_notifier
being invoked.

In addition it places stubs in place for the main entry points by
follow on code.

Follow up patches will complete the implementation of the interaction
with user space and makes use of these functions.
