3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Aaro Koskinen <aaro.koskinen@xxxxxx> commit f5d6a1441a5045824f36ff7c6b6bbae0373472a6 upstream. Currently IOP3XX_PERIPHERAL_VIRT_BASE conflicts with PCI_IO_VIRT_BASE: address size PCI_IO_VIRT_BASE 0xfee00000 0x200000 IOP3XX_PERIPHERAL_VIRT_BASE 0xfeffe000 0x2000 Fix by moving IOP3XX_PERIPHERAL_VIRT_BASE below PCI_IO_VIRT_BASE. The patch fixes the following kernel panic with 3.9-rc1 on iop3xx boards: [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 3.9.0-rc1-iop32x (aaro@blackmetal) (gcc version 4.7.2 (GCC) ) #20 PREEMPT Tue Mar 5 16:44:36 EET 2013 [ 0.000000] bootconsole [earlycon0] enabled [ 0.000000] ------------[ cut here ]------------ [ 0.000000] kernel BUG at mm/vmalloc.c:1145!
