#     powerpc/machdep: Convert ppc_md to static calls
#     
#     Static calls are global structures declared with DECLARE_STATIC_CALL()
#     and defined with DEFINE_STATIC_CALL().
#     
#     All fonction prototypes are moved out of struct machdep_calls into
#     struct machdep_calls_ops. That new struct won't be instanciated, it
#     is only used as a support for carriing fonction prototypes and use
#     them to declare/define associated static calls.
#     
#     In order to limit test copies which are error prone, define a macro
#     called PPC_MD_CALL, which either declare the call or defines it
#     based on the definition of GENERATING_PPC_MD_STATIC_CALLS_DEFINITIONS
#     that will be defined in and only in kernel/setup-common.c as a
#     replacement of ppc_md instance.
