Subject[PATCH 00/69] TTY buffer in tty_port -- prep no. 2

this is the second series of patches which allow tty buffers to be
moved from tty_struct (present from open to close/hangup) to tty_port
(present as long as the device). This will allow us to get rid of the
tty refcounting in the interrupt service routines and other hot paths
after we are done. This is because we won't need to handle races among
ISRs, timers, hangups and others, because tty_port lives as long as an
interrupt/timer tick may occur. Unlike tty_struct.

In this series, second batch of drivers is converted to use tty_port.
The final few pieces are to come in the next window. Read: only very
few drivers are remaining. Then the whole switch will start.

Standard x86 stuff was runtime-tested. The rest is only checked to be
compilation-errors free.
