Add some basic resume trace facilities
Considering that there isn't a lot of hw we can depend on during resume, this is about as good as it gets. This is x86-only for now, although the basic concept (and most of the code) will certainly work on almost any platform. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
