The existing implementation of swsusp_free iterates over all pfns in the system and checks every bit in the two memory bitmaps. This doesn't scale very well with large numbers of pfns, especially when the bitmaps are not populated very densly. Change the algorithm to iterate over the set bits in the bitmaps instead to make it scale better in large memory configurations. Also add a memory_bm_clear_current() helper function that clears the bit for the last position returned from the memory bitmap. This new version adds a !NULL check for the memory bitmaps before they are walked. Not doing so causes a kernel crash when the bitmaps are NULL.
