  ARC: smp: Rename platform hook @init_cpu_smp -> @init_per_cpu (2015-12-17
12:56:56 +0530)

----------------------------------------------------------------
ARC Fixes

 - perf interrupts on SMP: Not enabled (at boot) and disabled (at runtime)
 - stack unwinder regression (for modules, ignoring dwarf3)
 - nsim hosed for non default kernel link base builds
