[PATCH Resend 2/3] mips/mm: include _PAGE_SPECIAL in _PAGE_CHG_MASK

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



_PAGE_CHG_MASK contains the unchanged bits during pte_modify() and
pmd_modify(). All other architectures include the _PAGE_SPECIAL bit in
_PAGE_CHG_MASK, there is no reason that MIPS needn't.
