It looks like my solution changes the tpm module name to tpm-core.o.
This should be noted in the commit log:

In doing so we also change the core tpm module name from 'tpm' to 'tpm-core',
this is because kbuild does not like it if a multi-file module has a .c
file of the same name.

Is that OK? It follows the pattern other systems have in the kernel.

If this is not OK, then I think we have to rename tpm.c to tpm-XX.c to
make the build system work.

I've consolidated all the remarks and changes thus far on my github:
https://github.com/jgunthorpe/linux/commits/tpm-devel
ec94ce9d29298ba75cec83a136fd841f8da9d528

(plus 1 more untested patch to remove the tpm-bios module)

Jason
