Wow, lots of ibm folks on the cc :)  I can only talk about the mm related 
section mismatches, but these five can easily be solved with the

powerpc, mm: fix section mismatch for mark_reserved_regions_for_nid

mark_reserved_regions_for_nid() is only called from do_init_bootmem(), 
which is in .init.text, so it must be in the same section to avoid a 
section mismatch warning.
