Subject: [PATCH 25/31] powerpc/mm: Convert 4k insert from asm to C
Date: Mon, 21 Sep 2015 12:10:52 +0530 [thread overview]
Message-ID: <1442817658-2588-26-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1442817658-2588-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
This is similar to 64K insert. May be we want to consolidate
