#     powerpc/mmiowb: Hook up mmwiob() implementation to asm-generic code
#     
#     In a bid to kill off explicit mmiowb() usage in driver code, hook up
#     the asm-generic mmiowb() tracking code but provide a definition of
#     arch_mmiowb_state() so that the tracking data can remain in the paca
#     as it does at present
#     
#     This replaces the existing (flawed) implementation.
