ehea: Fix synchronization between HW and SW send queue
When memory is added to / removed from a partition via the Memory DLPAR
mechanism, the eHEA driver has to do a couple of things to reflect the
memory change in its own IO address translation tables. This involves
stopping and restarting the HW queues.
During this operation, it is possible that HW and SW pointer into these
queues get out of sync. This results in a situation where packets that
are attached to a send queue are not transmitted immediately, but
delayed until further X packets have been put on the queue.
This patch detects such loss of synchronization, and resets the ehea
port when needed.

net/compat/wext: send different messages to compat tasks
we had a race condition when setting and then
restoring frag_list. Eric attempted to fix it,
but the fix created even worse problems.
However, the original motivation I had when I
added the code that turned out to be racy is
no longer clear to me, since we only copy up
to skb->len to userspace, which doesn't include
the frag_list length. As a result, not doing
any frag_list clearing and restoring avoids
the race condition, while not introducing any
other problems.
Additionally, while preparing this patch I found
that since none of the remaining netlink code is
really aware of the frag_list, we need to use the
original skb's information for packet information
and credentials. This fixes, for example, the
group information received by compat tasks.

Prevent a TIPC node from sending out a LINK_STATE message
advertising a broadcast message that it is in the process
of sending, but has not yet actually sent. Previously, it was
possible for a link timeout to occur in between the time the
broadcast link updated its "last message sent" counter and the
time the broadcast message was passed to the broadcast bearer
for transmission. This ensures that the code which issues
the LINK_STATE message isn't informed of the new message until
the broadcast bearer has had a chance to send it.
Note: The "last message sent" value is stored in the "fsm_msg_count"
field of the link structure used by the broadcast link. Since the
broadcast link doesn't utilize the normal link FSM, this field can
be re-used rather than adding a new field to the broadcast link.

Allow TIPC's broadcast link to continue operation when it is unable
to send a message to all nodes in the cluster. Previously, the
broadcast link attempted to put the broadcast pseudo-bearer into a
blocked state; however, this caused a crash because the associated
bearer structure is only partially initialized. Further
investigation has revealed some conceptual problems with blocking
the pseudo-bearer; consequently, this functionality has been
disabled for the time being and the undelivered message is
eventually resent by the broadcast link's existing message
retransmission mechanism (if possible).
