#     powerpc/kernel/sysfs: Add new config option PMU_SYSFS to enable PMU SPRs sysfs file creation
#     
#     Many of the performance monitoring unit (PMU) SPRs are
#     exposed in the sysfs. This may not be a desirable since
#     "perf" API is the primary interface to program PMU and
#     collect counter data in the system. But that said, we
#     cant remove these sysfs files since we dont whether
#     anyone/anything is using them.
#     
#     So the patch adds a new CONFIG option 'CONFIG_PMU_SYSFS'
#     (user selectable) to be used in sysfs file creation for
#     PMU SPRs. New option by default is disabled, but can be
#     enabled if user needs it.
#     
#     Tested this patch behaviour in powernv and pseries machines.
#     Patch is also tested for pmac32_defconfig.
