[PATCH] swsusp: limit image size
Limit the size of the suspend image to approx. 500 MB, which should
improve the overall performance of swsusp on systems with more than 1 GB of
RAM.
It introduces the constant IMAGE_SIZE that can be set to the preferred size
of the image (in MB) and modifies the memory-shrinking part of swsusp to
take this constant into account (500 is the default value of IMAGE_SIZE).
