#     powerpc/hw_breakpoint: move instruction stepping out of hw_breakpoint_handler()
#     
#     On 8xx, breakpoints stop after executing the instruction, so
#     stepping/emulation is not needed. Move it into a sub-function and
#     remove the #ifdefs.

WARNING: vmlinux.o(.text+0x30ba): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
The function start_here_multiplatform() references
the function __init .early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of .early_setup is wrong.
