Re: [RFC][PATCH 2/3] swsusp: Do not use page flags

Hi!
Make swsusp use memory bitmaps instead of page flags for marking 'nosave' and
free pages. This allows us to 'recycle' two page flags that can be used for other
purposes. Also, the memory needed to store the bitmaps is allocated when
necessary (ie. before the suspend) and freed after the resume which is more
reasonable.
The patch is designed to minimize the amount of changes and there are some nice
simplifications and optimizations possible on top of it. I am going to
implement them separately in the future.

Looks ok, but needs to stay in -mm for a while. ACK.
Pavel
