From 66e9bbdb3dbb335b158bb88de2642966af816ffe Mon Sep 17 00:00:00 2001 From: Dominik Dingel Date: Mon, 6 Oct 2014 16:34:44 +0200 Subject: s390/mm: fixing calls of pte_unmap_unlock pte_unmap works on page table entry pointers, derefencing should be avoided. As on s390 pte_unmap is a NOP, this is more a cleanup if we want to supply later such function.
