From 5b24c421621792fcc588af6f644d6acf2dd798cc Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Thu, 2 Aug 2012 15:33:59 +0200 Subject: [PARISC] fix personality flag check in copy_thread() Directly comparing task_struct->personality against PER_* is not fully correct, as it doesn't take flags potentially stored in top three bytes into account. Analogically, directly forcefully setting personality to PER_LINUX32 or PER_LINUX discards any flags stored in the top three bytes.
