[Xen-devel] [PATCH v8 03/28] xen/arm: Set nr_cpu_ids to available number of cpus

[<vijayak@xxxxxxxxxxxxxxxxxx>]

From: Vijaya Kumar K <Vijaya.Kumar@xxxxxxxxxxxxxxxxxx>

nr_cpu_ids for arm platforms is incorrectly set to NR_CPUS
irrespective of the number of cpus supported by platform.

v6: - Updated nr_cpu_ids in setup.c instead of creating
      a helper function
