Subject: [PATCH] ia64: select CONFIG_TTY for use of tty_write_message in
 unaligned

arch/ia64/kernel/unaligned.c uses tty_write_message to print an
unaligned access exception to the TTY of the current user process.
Enable TTY to prevent a build error.

Not tested, but this *should* fix the build error with CONFIG_TTY=n.

Minimal fix, on the basis that few people on ia64 will care deeply about
kernel size enough to turn off TTY.  Ideally, I'd instead suggest
dropping the tty_write_message entirely, and just leaving the printk.
Bonus: no need to sprintf first.
