From 468138d78510688fb5476f98d23f11ac6a63229a Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 2 May 2017 19:52:17 -0400 Subject: binfmt_flat: flat_{get,put}_addr_from_rp() should be able to fail on MMU targets EFAULT is possible here. Make both return 0 or error, passing what used to be the return value of flat_get_addr_from_rp() by reference.
