From c642af9c41f09296997519499d16ff30e700816a Mon Sep 17 00:00:00 2001 From: Santosh Sivaraj Date: Tue, 27 Jun 2017 12:30:06 +0530 Subject: [PATCH] powerpc/smp: Convert NR_CPUS to nr_cpu_ids nr_cpu_ids can be limited by nr_cpus boot parameter, whereas NR_CPUS is a compile time constant, which shouldn't be compared against during cpu kick.
