-From: Gerald Schaefer <geraldsc@de.ibm.com>
-Subject: kernel: setting 32 bit personality doesn't work
-References: bnc#466462
-
-Symptom:     Setting the personality from 64 bit to 32 bit and afterwards
-             issueing a uname system call will return that the environment
-             is still 64 bit. Some executables that rely on a correct 32 bit
-             environment don't work.
-Problem:     The SET_PERSONALITY macro compares the whole personality field
-             on each execve with PER_LINUX32. If that doesn't match personality
-             is set to PER_LINUX. When some higher order bits in the personality
-             field are set the personality is incorrectly changed from
-             PER_LINUX32 to PER_LINUX on execve.
-Solution:    Use the personality() function to mask out bits that shouldn't be
-             taken into account when comparing personality types.
