I just noticed this:
#define _PAGE_TABLE (_PAGE_PRESENT | _PAGE_RW | _PAGE_USER | \
_PAGE_ACCESSED | _PAGE_DIRTY)
#define _KERNPG_TABLE (_PAGE_PRESENT | _PAGE_RW | _PAGE_ACCESSED | \
_PAGE_DIRTY)
Is there a reason we set _PAGE_DIRTY for page tables? It has no
function, but doesn't do any harm either (the dirty bit is ignored for
page tables)... it just looks funny to me.
