PM: Optional beeping during resume from suspend to RAM
Add a feature allowing the user to make the system beep during a resume from suspend to RAM, on x86_64 and i386. This is useful for the users with broken resume from RAM, so that they can verify if the control reaches the kernel after a wake-up event. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
