[PATCH] swsusp: add architecture special saveable pages support
1. Add architecture specific pages save/restore support. Next two patches will use this to save/restore 'ACPI NVS' pages. 2. Allow reserved pages 'nosave'. This could avoid save/restore BIOS reserved pages. Signed-off-by: Shaohua Li <shaohua.li@intel.com> Cc: Pavel Machek <pavel@ucw.cz> Cc: "Rafael J.
