[PATCH] swsusp: add resume_offset command line parameter
Add the kernel command line parameter "resume_offset=" allowing us to specify the offset, in <PAGE_SIZE> units, from the beginning of the partition pointed to by the "resume=" parameter at which the swap header is located. This offset can be determined, for example, by an application using the FIBMAP ioctl to obtain the swap header's block number for given file.
