From 04a8645304500be88b3345b65fef7efe58016166 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 5 Mar 2019 15:46:29 -0800 Subject: mm: update ptep_modify_prot_commit to take old pte value as arg Architectures like ppc64 require to do a conditional tlb flush based on the old and new value of pte. Enable that by passing old pte value as the arg.
