Subject: [PATCH 2/3] mips/mm: include _PAGE_SPECIAL in _PAGE_CHG_MASK
Date: Fri, 31 Jul 2020 18:12:50 +0800 [thread overview]
Message-ID: <1596190371-17405-2-git-send-email-chenhc@lemote.com> (raw)
In-Reply-To: <1596190371-17405-1-git-send-email-chenhc@lemote.com>
_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.
