#     powerpc/8xx: regroup TLB handler routines
#     
#     As this is running with MMU off, the CPU only does speculative
#     fetch for code in the same page.
#     
#     Following the significant size reduction of TLB handler routines,
#     the side handlers can be brought back close to the main part,
#     ie in the same page.
