There was a more complete patch by Randy Dunlap posted a couple of
days ago that I queued for the next Calgary update. However, since
people are tripping over this and are bothered enough to send patches,
Andi or Andrew, could you please expedite the attached patch upstream?

Fix section mismatch warnings:
these functions are called only from __init functions.

WARNING: vmlinux.o(.text+0x1861c): Section mismatch: reference to .init.text:free_bootmem (between 'free_tce_table' and 'build_tce_table')
WARNING: vmlinux.o(.text+0x187e5): Section mismatch: reference to .init.text:__alloc_bootmem_low (between 'alloc_tce_table' and 'kretprobe_trampoline_holder')
