The comments concerning how the pcnet32 ethernet device driver selects
the MAC addr to use are incorrect. A recent patch (in the last 3 months)
changed how the code worked, but did not change the comments.
Side comment: the new behaviour is good; I've got a pcnet32 card which
powers up with garbage in the CSR's, and a good MAC addr in the PROM.

Initializing the b44 MAC & PCI functional blocks in the controller must

I'm not really certain what the thinking was but the code obviously wanted to
walk processes other than just those in it's session, for purposes of do_SAK.
Just walking those tasks that don't have a session assigned sounds at the very
least incomplete.
So modify the code to kill everything in the session and anything else that
might have the tty open. Hopefully this helps if the do_SAK functionality is
ever finished.

Speed up SRAM read and write functions if possible by using MMIO
instead of config. cycles. With this change, the post reset signature
done at the end of D3 power change must now be moved before the D3
power change.
IBM reported a problem on powerpc blades during ethtool self test
that was caused by the memory test taking excessively long. Config.
cycles are very slow on powerpc and the memory test can take more
than 10 seconds to complete using config. cycles. As a result, NETDEV
WATCHDOG can be triggered during self test and the chip can end up in
a funny state.

When a new SBP-2 unit is added, sbp2 now takes a reference on the 1394
low-level driver (ohci1394 or pcilynx). This prevents the 1394 host driver
module from being unloaded, e.g. by an administrative routine cleanup of
unused kernel modules or when another 1394 driver which depends on ohci1394
is unloaded.
The reference is dropped when the SBP-2 unit was disconnected, when sbp2 is
unloaded or detached from the unit, or when addition of the SBP-2 unit failed.
