From 53571ce47010562f5e67782ea00206f379a5cd65 Mon Sep 17 00:00:00 2001 From: Thiemo Seufer Date: Sun, 13 Aug 2006 00:53:29 +0100 Subject: [PATCH] [MIPS] Fix O32 personality(2) call with 0xffffffff argument. A sign extension bug did result in sys_personality being invoked with a 0xffffffffffffffffUL argument, so querying the current personality didn't work.
