$ uname -a
Linux mpc8536-1 3.12.1-rt3-00281-g9de268d #76 SMP PREEMPT RT Fri Nov 22 16:53:05 CET 2013 ppc GNU/Linux
$ uptime
22:01:10 up 22 days, 21:01, 1 user, load average: 443.08, 563.59, 586.20
This is from a mpc8536 box. The high load comes from a hackbench that was
running for quite some time. Are Book-E (CONFIG_PPC_BOOK3E_MMU without
CONFIG_PPC_BOOK3E set) not affected or is this bug not present if a SMP
kernel is booted on a UP machine?
