We got a little mixed up with what the backoff member holds in the
IPoIB multicast group structure: sometimes it was used as a number of
seconds, and sometimes it was used as a number of jiffies. Fix the
code so that backoff is always in seconds.

Since ipoib uses queue_delayed_work to run flush task on port state events,
it must flush scheduled work after unregistering the event handler.

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.

Currently we may have work scheduled in default kernel workqueue when
the device is going down. The device could get freed before this
workqueue gets serviced. I am actually seeing this causing system
hangs.
The following patch fixes this by using ipoib_workqueue which gets
flushed when the device is going down.

Always make sure that the full membership bit is set in the P_Keys
that IPoIB uses. This makes sure that all hosts join the correct
multicast groups so that hosts that are partial partition members
can talk to the rest of the network.

changing CONFIG_LOCALVERSION rebuilds too much, for no appearent reason.

RARP replies are another valid case where IPoIB may need to send a
unicast packet with no neighbour structure.

Correct and simplify calculation of static rate. We need to round up the
quotient of (local_rate - path_rate) / path_rate. To round up we add
(path_rate - 1) to the numerator, so the quotient simplifies to (local_rate -
1) / path_rate.
No idea how I came up with the old formula.

Set skb->mac.raw on receive. This fixes crashes when this is
dereferenced, for example by netfilter or when PF_PACKET is used.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
