[PATCH] swsusp: improve freeing of memory
This patch makes swsusp free only as much memory as needed to complete the suspend and not as much as possible.  In the most of cases this should speed up the suspend and make the system much more responsive after resume, especially if a GUI (eg. X Windows) is used. If needed, the old behavior (ie to free as much memory as possible during suspend) can be restored by unsetting FAST_FREE in power.h Signed-off-by: Rafael J.
