78e21ab011 Simplify the "and if we're in the debugger, don't use locks" logic,
correcting some misthinking.

faabfac9ff When entering siocnputc() with (kdb_active), don't acquire (or
release) the sio spin mutex, as use of synchronization primitives in
the debugger can result in substantial problems.  With this patch in
place entering the debugger via a serial console is made
substantially more reliable.

e5979322ba Remove local hacks to set flags now that the device probe does this for us.
Tested on every device except sio_pci and the pc98 fd.c.  Perhaps something
similar should be done for the "disabled" hints also.

Use the init/lock*in/out fields in struct tty and remove them from our softc.

Use tty->t_sc to find out softc when convenient.

a7092dac2e If you insert a pccard modem and then eject it, you get a panic. This
happens because the sio device was never opened and com->tp is
therefore NULL.  ttygone can't swallow a NULL, so guard against that
possibility.  Other places in this function make similar checks, so I
believe this is correct.

672c05d49c Preparation commit for the tty cleanups that will follow in the near
future:

rename ttyopen() -> tty_open() and ttyclose() -> tty_close().

We need the ttyopen() and ttyclose() for the new generic cdevsw
functions for tty devices in order to have consistent naming.

6af8e47df7 Update for the KDB framework. Sanitize the alpha console code now that
it's in the way even more. Basicly: remove all alpha specific console
support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console
initialization to be identical to all other platforms. In a nutshell:
call cninit().
The platform specific code now only sets or clears RB_SERIAL and thus
automaticly causes the right console to be selected.

sio.c:
o  Replace the remote GDB hacks and use the GDB debug port interface
   instead.
o  Make debugging code conditional upon KDB instead of DDB.
o  Call kdb_alt_break() instead of db_alt_break().
o  Call kdb_enter() instead of breakpoint().
o  Remove the ugly compatibility of using the console as the debug
   port.

3df6c4de7e - Shorten the names for the TTY related swi interrupt handlers as the
'tty:' prefix is largely redundant.
- Fix the priority of the low-priority TTY SWIs that are hung off of the
  softclock thread.

cb9ea5f4cb Pick the hotchar out of the tty structure instead of caching private
copies.

No current line disciplines have a dynamically changing hotchar, and
expecting to receive anything sensible during a change in ldisc is
insane so no locking of the hotchar field is necessary.

13e84a71e0 Centralize the line discipline optimization determination in a function

33c5911242 Some enhancements and bug fix.
-  Define option FORCECONSPEED to force the serial console to
        be CONSPEED.  I've run into a lot of boards in which
        the detect for prior speed doesn't work and ends up with
        broken console since it is at the wrong speed.
     -  If a serial port is marked as a console, but console=vidconsole
        and if the serial ports doesn't exist it will be probed and
        attached at a 8250 chip.  Then writes to that will freeze the
        system.
     -  Add an option flags 0x400000 to mark this as a potential
        comconsole in-case the one flaged with 0x10 does not exist
        in the system.

This makes it easier to deploy on systems with one or two serial ports.
