This patch removes all occurances of _INLINE_ in the kernel.
With the exception of tty_flip.h, I've simply removed the inline's since
gcc should know best which functions to be inlined.

The patch does the following for v441xx seris drivers:
- stop using platform_device_register_simple() as it is going away
- mark ->probe() and ->remove() methods as __devinit and __devexit
respectively
- initialize "owner" field in driver structure so there is a link
from /sys/modules to the driver
- mark *_init() and *_exit() functions as __init and __exit

Update the serial_txx9 driver.
* More strict check in verify_port. Cleanup.
* Do not insert a char caused previous overrun.
* Fix some spin_locks.
* Do not call uart_add_one_port for absent ports.
Also, this patch removes a BROKEN tag from Kconfig. This driver has been
marked as BROKEN by removal of uart_register_port, but it has been solved
already on Sep 2005.

Glen Turner reported that writing LFCR rather than the more
traditional CRLF causes issues with some terminals.
Since this aflicts many serial drivers, extract the common code
to a library function (uart_console_write) and arrange for each
driver to supply a "putchar" function.

Because we play this trick where we use ttyS? in increasing minor
numbers for different sunfoo.c drivers, we have to inform the TTY
layer of this.
Do so by setting the tty->name_base appropriately.
Probably there should be a generic way to do this in the serial core,
but for now...

Add udelay to polling console write loop, and increment

Name the device "ttyHV" and pass that to add_preferred_console()

Kill sunhv_console_setup(), it's empty.
Handle the case where we don't want to use hypervisor console.

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.

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.

serial8250_console_write() was updating the IER in hardware without

It seems serial_core intend to initialize port->lock just once for each
ports. This is done in uart_set_options() for console, and in
uart_add_one_port() for other ports. But there is a case the port->lock is
not initialized by serial_core. If the setup function for the console was
failed, it will not call uart_set_options() but the port is marked as
console (uart_console(port) returns 1). It can happen if console was PCI
port which can not detected at the time of register_console.
This patch is to initialize port->lock for such console port. With this
change, most of spin_lock_init() (some of them are labeled "Temporary
fix.") in low-level serial drivers can be omitted.

Same reasoning as commit 747c8a5594
but this time we're making uart_port flags a bitwise type - not
all of these flags correspond with the old ASYNC_ flags, so there
is the possibility for bugs if the wrong ASYNC_* constants are
used. Always use UPF_* constants for uart_port->flags.
