From a7f4ee1fe93aa9ae191971be9324edb8f9fbcb4a Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Sat, 4 Apr 2015 19:28:50 +1100 Subject: powerpc: Drop return value of smp_ops->probe() smp_ops->probe() is currently supposed to return the number of cpus in the system. The last actual usage of the value was removed in May 2007 in e147ec8f1808 "[POWERPC] Simplify smp_space_timers". We still passed the value around until June 2010 when even that was finally removed in c1aa687d499a "powerpc: Clean up obsolete code relating to decrementer and timebase". So drop that requirement, probe() now returns void, and update all implementations.
