As I mentioned to a few ppc folks at LCA08 I plan to use
the LMB code from powerpc as a basis for NUMA support on
sparc64.
There are two changes.
1) Move arch/powerpc/mm/lmb.c to lib/lmb.c, put the main
interface bits in include/linux/lmb.h, put arch-specific
bits in asm/lmb.h and add

Review had been easier if the patch was inlined.
Sorry :)
Can we plase have this changed to use:
config SPARC64
+ select HAVE_LMB
And then in lib/Kconfig have
+config HAVE_LMB
+ bool
So we avoid

Does sparc have the concept of a phys_addr_t? We are in the process
of expanding the lmb support to deal with 36-bit physical addresses on
32-bit machines.
On sparc64, where I intend to use this, unsigned long's are
Convert the lmb code to use phys_addr_t instead of unsigned long for
physical addresses and sizes. This is needed to support large amounts
of RAM on 32-bit systems that support 36-bit physical addressing.
Built/booted on mpc8641; build tested on pasemi and 44x.
