Hi Linus,

This is the second group of code for the 4.7 merge window.  It looks
large, but only in one sense.  I'll get to that in a minute.  The list
of changes here breaks down as follows:

Round two of 4.7 merge window patches

- Dynamic counter infrastructure in the IB drivers  <- 1 patch
  This is a sysfs based code to allow free form access to the hardware
  counters RDMA devices might support so drivers don't need to code
  this up repeatedly themselves
- SendOnlyFullMember multicast support              <- 4 patches
- IB router support                                 <- 4 patches
- A couple misc fixes                               <- 4 or so here
- The big item on the list: hfi1 driver updates, plus moving the hfi1
  driver out of staging                             <- everything else

There was a group of 15 patches in the hfi1 list that I thought I had in
the first pull request but they weren't.  So that added to the length of
the hfi1 section here.

As far as these go, everything but the hfi1 is pretty straight forward.
The hfi1 is, if you recall, the driver that Al had complaints about how
it used the write/writev interfaces in an overloaded fashion.  The write
portion of their interface behaved like the write handler in the IB
stack proper and did bi-directional communications.  The writev
interface, on the other hand, only accepts SDMA request structures.  The
completions for those structures are sent back via an entirely different
event mechanism.  With the security patch, we put security checks on the
write interface, however, we also knew they would be going away soon.
Now, we've converted the write handler in the hfi1 driver to use ioctls
from the IB reserved magic area for its bidirectional communications.
With that change, Intel has addressed
all of the items originally on their TODO when they went into staging
(as well as many items added to the list later).  As such, I moved them
out, and since they were the last item in the staging/rdma directory,
and I don't have immediate plans to use the staging area again, I
removed the staging/rdma area.  Because of the move out of staging, as
well as a series of 5 patches in the hfi1 driver that removed code
people thought should be done in a different way and was optional to
begin with (a snoop debug interface, an eeprom driver for an eeprom
connected directory to their hfi1 chip and not via an i2c bus, and a few
other things like that), the line count, especially the removal count,
is high.

I know we have a long weekend coming up, so I wanted to get this out
before Friday so you had plenty of time to digest and look it over.  Let
me know if you see anything amiss.

Now the boilerplate:

The following changes since commit c16d2750a08c8ccaf98d65f287a8aec91bb9610d:
