ARC: Adjust cpuinfo for non-continuous cpu ids
num_possible_cpus() returns how many CPUs may be present on system. However we want the highest possible CPU number. This may be differ in a sparsed possible CPUs map. Such map achived by OF for plat-eznps. For example if we have: possible cpus mask 0,3 Then: num_possible_cpus() is equal 2 while nr_cpu_ids is equal 4. Only for value 4 c_start() will provide correct cpuinfo at procfs. Signed-off-by: Noam Camus <noamc@ezchip.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
