#     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.

WARNING: vmlinux.o(.text.unlikely+0x51d8): Section mismatch in reference from the function .remove_pmd_table() to the function .meminit.text:.split_kernel_mapping()
The function .remove_pmd_table() references
the function __meminit .split_kernel_mapping().
This is often because .remove_pmd_table lacks a __meminit 
annotation or the annotation of .split_kernel_mapping is wrong.
