rmap: fixup page_referenced() for nommu systems
After the recent changes that went into mm/vmscan.c to overhaul stuff, we ended up with these warnings on no-mmu systems: mm/vmscan.c: In function `shrink_page_list': mm/vmscan.c:580: warning: unused variable `vm_flags' mm/vmscan.c: In function `shrink_active_list': mm/vmscan.c:1294: warning: `vm_flags' may be used uninitialized in this function mm/vmscan.c:1242: note: `vm_flags' was declared here This is because the no-mmu function defines page_referenced() to work on the first argument only (the page). It does not clear the vm_flags given to it because for no-mmu systems, they never actually get utilized. Since that is no longer strictly true, we need to set vm_flags to 0 like everyone else so gcc can do proper dead code elimination without annoying us with unused warnings.
