This patch removes the dependency that swap suspend currently has on
PageReserved. In the places where PageReserved is currently set and
cleared, we also set and clear PageNosave, and in swap suspend itself,
we only reference PageNosave. The ongoing effort at freeing PageReserved
thus achieves another step forward.
Any reason you can't use page_is_ram directly? I would rather you
do this than moving swsusp specific flags out into the wider tree.
The reason is that these flags now become just as hard to kill as
PageReserved is.
You'll have to slightly modify i386's page_is_ram, because it
appears that you'll actually want
'page_is_ram(pfn) && !(bad_ppro && page_kills_ppro(pfn))'
Thanks, glad someone is looking into this!
