shared_cpu_list sysfs file is missing in powerpc and shared_cpu_map gives an
extra newline character.

Before this patchset
# ls /sys/devices/system/cpu0/cache/index1
coherency_line_size  number_of_sets  size  ways_of_associativity
level                shared_cpu_map  type
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map
00ff

#
		(Notice the extra blank line).

After this patchset
# ls /sys/devices/system/cpu0/cache/index1
coherency_line_size  number_of_sets   shared_cpu_map  type
level                shared_cpu_list  size            ways_of_associativity
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map
00ff
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_list
0-7
#

Srikar Dronamraju (3):
  powerpc/cacheinfo: Use cpumap_print to print cpumap
  powerpc/cacheinfo: Make cpumap_show code reusable
  powerpc/cacheinfo: Add per cpu per index shared_cpu_list
