Michael Ellerman 8c20fafa85 [PATCH] powerpc: Make sure we don't create empty lmb regions 
To prevent problems later in boot, make sure we don't create zero-size lmb
regions.

I've checked all the callers, and at the moment no one should ever hit this.
All callers use a constant size, or they check the computed size before they
call us.

Michael Ellerman eb481899aa [PATCH] powerpc: Fixup debugging in lmb.c 
Somewhere we lost the include of udbg.h in lmb.c. While we're there, add a DBG
macro like every other file has and use it in lmb_dump_all().

Paul Mackerras 7c8c6b9776 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.
