From 9a06c3b176976919e223844f8ed9f1acae20b433 Mon Sep 17 00:00:00 2001 From: Adrian Cox Date: Fri, 17 Nov 2006 14:35:48 +0000 Subject: [PATCH] [POWERPC] Fix wraparound problem in smp-tbsync on 32-bit The patch below fixes an arithmetic wrap-around issue on 32bit machines using smp-tbsync. Without this patch a timebase value over 0x000000007fffffff will hang the boot process while bringing up secondary CPUs.
