[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.
