Subject: NR_CPUS: Replace NR_CPUS in arch/x86/kernel/genx2apic_uv_x.c
X-Git-Tag: firefly_0821_release~19443^2~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=247bc6ca0f691e4617e7bdb70cbaccc939f754ec;p=firefly-linux-kernel-4.4.55.git

NR_CPUS: Replace NR_CPUS in arch/x86/kernel/genx2apic_uv_x.c

  * Replace NR_CPUS loop with for_each_possible_cpu().

  * nr_cpu_ids should be used to determine if a percpu area is
    available for a given cpu.
