From 68a7439a150d6b4da99082ab454b9328b151bc25 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Mon, 2 Sep 2013 18:43:31 +0200 Subject: Revert "memory: Return -1 again on reads from unsigned regions" This reverts commit 9b8c69243585a32d14b9bb9fcd52c37b0b5a1b71. The commit was wrong: We only return -1 on invalid accesses, not on valid but unbacked ones. This broke various corner cases.
