Remove all #inclusions of asm/system.h preparatory to splitting and killing
it.  Performed with the following command:

perl -p -i -e 's!^#\s*include\s*<asm/system[.]h>.*\n!!' `grep -Irl '^#\s*include\s*<asm/system[.]h>' *`

Jiri Slaby 410235fd4d TTY: remove unneeded tty->index checks
Checking if tty->index is in bounds is not needed. The tty has the
index set in the initial open. This is done in get_tty_driver. And it
can be only in interval <0,driver->num).

So remove the tests which check exactly this interval. Some are
left untouched as they check against the current backing device count.
(Leaving apart that the check is racy in most of the cases.)

Jiri Slaby 2f16669d32 TTY: remove re-assignments to tty_driver members
All num, magic and owner are set by alloc_tty_driver. No need to
re-set them on each allocation site.

pti driver sets something different to what it passes to
alloc_tty_driver. It is not a bug, since we don't use the lines
parameter in any way. Anyway this is fixed, and now we do the right
thing.

Jiri Slaby 8bab534b50 TTY: mxser+cyclades remove wait_until_sent debug code
It makes the code really ugly. And since it can be enabled only before
building and only in the source files, it can be barely used by users.
That said, I've not seen anybody to use it in the past few years.

This crap is copied to some more drivers over the tty tree. Since I'm
not their maintainer, I'm not sure if I should remove them too?

Manuel Zerpies 5a3c6b251d drivers/tty: use printk_ratelimited() instead of printk_ratelimit()
Since the printk_ratelimit() shouldn't be used anymore (see comment in
include/linux/printk.h), replace it with printk_ratelimited().
