powerpc: Merge lmb.c and make MM initialization use it.
This also creates merged versions of do_init_bootmem, paging_init and mem_init and moves them to arch/powerpc/mm/mem.c. It gets rid of the mem_pieces stuff. I made memory_limit a parameter to lmb_enforce_memory_limit rather than a global referenced by that function. This will require some small changes to ppc64 if we want to continue building ARCH=ppc64 using the merged lmb.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
