[SERIAL PATCH] updates

[Russell King]

This is the stuff I've collected since 2.5.41; this will go to Linus in
the next day or so.  Can people please test this out.

(The serialP.h changes are especially important; my greps of the tree
show that this should be safe.  I plan to fix that up and coming
parport_serial problem with SIIG stuff without involving struct
pci_board.)

If people want to pull from me, I'm quite happy for folk to do so, but
please mail me first; the tree isn't guaranteed to have only serial
stuff in and can have stuff added at any time - it even changes use
between the times when Linus pulls from it.

Thanks.
