From Rob Herring:
highbank fixes for 3.8
-Compile fix for !SMP
-More cpu cluster id related fixes
* tag 'highbank-fixes-for-3.8' of git://sources.calxeda.com/kernel/linux:
ARM: highbank: mask cluster id from cpu_logical_map
ARM: scu: mask cluster id from cpu_logical_map
ARM: scu: add empty scu_enable for !CONFIG_SMP
