Subject: [PATCH Resend 2/3] mips/mm: include _PAGE_SPECIAL in _PAGE_CHG_MASK
Date: Sun,  1 Nov 2020 11:33:57 +0800	[thread overview]
Message-ID: <1604201638-4001-2-git-send-email-chenhc@lemote.com> (raw)
In-Reply-To: <1604201638-4001-1-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.
