From 90eac727c6d7afbe707ce408edf97c33385fa08c Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 21 Oct 2005 16:01:33 +1000 Subject: [PATCH] powerpc: Don't blow away load_addr in start_thread The patch to make process.c work for 32-bit and 64-bit (06d67d54741a5bfefa31945ef195dfa748c29025) broke some 64-bit binaries. We were blowing away load_addr in gpr[2], so we weren't properly relocating the entry point.
