Subject: [PATCH] ppc: Make PPC_BOOK3S_64 select IRQ_WORK

arch/powerpc/kernel/mce.c, compiled in for PPC_BOOK3S_64, calls
functions only built when IRQ_WORK, so select it. Fixes the following
build error:

arch/powerpc/kernel/built-in.o: In function `.machine_check_queue_event':
(.text+0x11260): undefined reference to `.irq_work_queue'

Subject: [PATCH] ia64: select CONFIG_TTY for use of tty_write_message in unaligned
Date: Wed, 26 Feb 2014 02:15:56 -0800

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.

Date: Wed, 26 Feb 2014 18:13:06 -0800

The unconditionally built keyboard driver, drivers/s390/char/keyboard.c,
requires CONFIG_TTY, so select it from CONFIG_S390 to prevent a build
error.
