During a code scan for another change I discovered that this call to
pcnet32_free_ring must be removed. If the open fails due to a lack of
memory all the ring structures are removed via the call to free_ring
and a subsequent call to open will dereference a null pointer in
pcnet32_init_ring.
Please apply to 2.6.17.

Someone was waaay too aggressive and removed e1000's reboot notifier
instead of porting it to the new way of the shutdown handler. This change
broke wake on lan. Add the shutdown handler back in using the same method
as e100 uses.

The TPM chip on the ThinkPad T60 and Z60 machines is returning 0xFFFF for
the vendor ID which is a check the driver made to double check it was
actually talking to the memory mapped space of a TPM. This patch removes
the check since it isn't absolutely necessary and was causing device
discovery to fail on these machines.

For a very long time, echoing 'standby' or 'mem' into /sys/power/state has
killed the machine on powerpc. This patch fixes that.
This patch adds the .valid callback to pm_ops on PowerMac so that only the
suspend to disk state can be entered. Note that just returning 0 would
suffice since the upper layers don't pass PM_SUSPEND_DISK down, but we
handle it there regardless just in case that changes.

If we post a list of length exactly a multiple of 256, nreq in
doorbell gets set to 256 which is wrong: it should be encoded by 0.
This is because we only zero it out on the next WR, which may not be
there. The solution is to ring the doorbell after posting a WQE, not
before posting the next one.
This is the same bug that we just fixed for QPs with non-shared RQ.

It looks like metapage_releasepage was making in invalid assumption that
the releasepage method would not be called on a dirty page. Instead of
issuing a warning and releasing the metapage, it should return 0, indicating
that the private data for the page cannot be released.
I also realized that metapage_releasepage had the return code all wrong. If
it is successful in releasing the private data, it should return 1, otherwise
it needs to return 0.
Lastly, there is no need to call wait_on_page_writeback, since
try_to_release_page will not call us with a page in writback state.

Since packet might arrive after or during removal, need to clear

The problem was that node A's sending thread, which handles sending RDMA
read response data, would write the trigger word, the last packet would
be sent, node B would send a new RDMA read request, node A's interrupt
handler would initialize s_rdma_sge, then node A's sending thread would
update s_rdma_sge. This didn't happen very often naturally but was more
frequent with 1 byte RDMA reads. Rather than adding more locking or
increasing the QP structure size and copying sge data, I modified the
copy routine to update the pointers before writing the trigger word to
avoid the update race.
