Make swsusp actually work

[Pavel Machek]

Hi!

There were two bugs, and linux/mm.h one took me *very* long to
find... Well, those bits used for zone should have been marked. Plus I
hack ide_..._suspend code not to panic, and it now seems to
work. [Sorry, 2pm, have to get some sleep.]

Please apply,
								Pavel
