[PATCH] swsusp: introduce the swap map structure
This patch introduces the swap map structure that can be used by swsusp for keeping tracks of data pages written to the swap.  The structure itself is described in a comment within the patch. The overall idea is to reduce the amount of metadata written to the swap and to write and read the image pages sequentially, in a file-alike way. This makes the swap-handling part of swsusp fairly independent of its snapshot-handling part and will hopefully allow us to completely separate these two parts in the future. This patch is needed to remove the suspend image size limit imposed by the limited size of the swsusp_info structure, which is essential for x86-64 systems with more than 512 MB of RAM.
