PM / Hibernate: Compress hibernation image with LZO
Compress hibernation image with LZO in order to save on I/O and therefore time to hibernate/thaw. [rjw: Added hibernate=nocompress command line option instead of just nocompress which would be confusing, fixed a couple of compiler warnings, fixed kerneldoc comments, minor cleanups.] Signed-off-by: Bojan Smojver <bojan@rexursive.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
