Get rid of the local 'flip' variable and no need to 'trim' the buffer.

We're presently getting oopses because Bluetooth (and possibly other) drivers
are calling core functions after things have been shut down.
So rather than oopsing, let's drop a warning then take avoiding action, so the
machine survives. Once all the sub-drivers are fixed up we can remove the
take-avoiding-action part.

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:
[IA64] mca recovery return value when no bus check
[IA64] SGI SN drivers: don't report !sn2 hardware as an error
[IA64] don't report !sn2 or !summit hardware as an error
[IA64] gensparse_defconfig: turn on PNPACPI
[IA64] Increase severity of MCA recovery messages
This stuff is all in the generic ia64 kernel, and the new initcall error
reporting complains about them.

Incorrect uart_write_wakeup() calls cause reference to a NULL tty
pointer. This has been fixed in the sunsab and sunzilog serial drivers
in October 2005. Update the ip22zilog, which is based on sunzilog,
accordingly.

early_serial_setup() must not be called after console initialisation.
Add a comment prior to the function explicitly stating this.

Serial drivers in general should not write uart_info->flags - they're
private to serial_core. Serial drivers have no need to fiddle with
tty->alt_speed, nor manipulate TTY_IO_ERROR in tty->flags. Fix the
ioc4 serial driver for both these points by simply removing the
offending code.

On some embedded PowerPC (MPC834x) systems an extra byte would some
times be required to flush data out of the fifo.
serial8250_console_write() was updating the IER in hardware without
also updating the copy in uart_8250_port. This causes issues functions
like serial8250_start_tx() and __stop_tx() to misbehave.
