[PATCH] Make swsusp avoid memory holes and reserved memory regions on x86_64
On x86_64 machines with more than 2 GB of RAM there are large memory gaps
(with no corresponding kernel virtual addresses) and reserved memory
regions between areas of usable physical RAM. Moreover, if CONFIG_FLATMEM
is set, they appear within the normal zone. swsusp should not try to save
them, so the corresponding page structs have to be marked as 'nosave'.
