#     powerpc/mm: Move the linear_mapping_mutex to the ifdef where it is used
#     
#     The mutex linear_mapping_mutex is defined at the of the file while its
#     only two user are within the CONFIG_MEMORY_HOTPLUG block.
#     A compile without CONFIG_MEMORY_HOTPLUG set fails on PREEMPT_RT because
#     its mutex implementation is smart enough to realize that it is unused.
#     
#     Move the definition of linear_mapping_mutex to ifdef block where it is
#     used.
#
