#     powerpc/powernv: Fix type of opal_mpipl_query_tag() addr argument
#     
#     opal_mpipl_query_tag() takes a pointer to a 64-bit value, which firmware
#     writes a value to. As OPAL is traditionally big endian this value will
#     be big endian.
#     
#     This can be confirmed by looking at the implementation in skiboot:
#     
#       static uint64_t opal_mpipl_query_tag(enum opal_mpipl_tags tag, __be64 *tag_val)
#       {
#             ...
#             *tag_val = cpu_to_be64(opal_mpipl_tags[tag]);
#             return OPAL_SUCCESS;
#       }
#     
#     Fix the declaration to annotate that the value is big endian.
