A set of patches that attempts to improve page flag handling.

First darn thing I tried was i386 allnoconfig and it goes splat.

In file included from include/linux/mm.h:192,
from kernel/bounds.c:8:
include/linux/page-flags.h: In function 'PageHighMem':
include/linux/page-flags.h:180: error: implicit declaration of function 'page_zone'

There's also a parenthesis mismatch so it looks like it was neither compile-time nor runtime tested on i386. Sorry, but I don't have the time to be the first one to try this out.

To fix this page-flags.h needs to include mm.h, but mm.h includes page-flags.h. Making PageHighMem a macro would be the expedient fix.
