From e4c1112c3fc503fc78379fa61450bfda3f0717fe Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 29 May 2018 19:58:40 +0530 Subject: powerpc/mm: Change function prototype In later patch, we use the vma and psize to do tlb flush. Do the prototype update in separate patch to make the review easy.
