From 03e4c49f847f23c62900424f65a62f76de5a7151 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 23 Jan 2009 16:40:23 +0100 Subject: [S390] personality: fix personality loss on execve Use the personality() macro to mask out all bits that are not relevant for the personality type. The personality field contains bits for other things as well, so without masking out the not relevalent bits the comparison won't do what is expected.
