Subject: [PATCH V3 07/10] powerpc/mm: Define _PAGE_SOFT_DIRTY unconditionally
Date: Tue, 21 Mar 2017 22:59:57 +0530 [thread overview]
Message-ID: <1490117400-9891-7-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1490117400-9891-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
Conditional PTE bit definition is confusing and results in coding error.
Reviewed-by: Paul Mackerras <paulus@ozlabs.org>
