FYI:
I've applied the patch below to the 2.6.16 tree to fix the UML
compilation on systems with recent kernel headers.
Please complain if anything is wrong with it.

Eliminate the open_mutex after complaints from Blaisorblade. It turns
out that the tty count provides the information needed to tell whether

Post-2.6.20 material.
The locking fixes are mostly commenting the lack of locking or are making
things const.
There's a bunch of code cleanup - elimination of dead code, unused parameters,
and unused structure fields - and some formatting fixes.

The chan_opts structure is mostly const, and needs no locking.
Comment the lack of locking on the one field that can change.
Make all the other fields const.
It turned out that console_open_chan didn't use its chan_opts
argument, so that is deleted from the function and its callers.

Comment some lack of locking in the iomem driver.
Also, a couple of variables are in the wrong place, so they are moved.

Remove the last vestiges of devfs from console registration. Change
the name of the function, plus remove a couple of unused fields from
the line_driver structure.
struct lines is no longer needed, all traces of it are gone.
The only way that I can see to mark a structure as being almost-const
i
Whitespace fixes and emacs comment removal.
