to be more accurate, the following other config:

       CONFIG_BUILD_ELF64=y and kernel load address in CKSEG0

should theoretically work but currently doesn't because of __pa() introduction.

This config should not be used because it's normally not interesting
for normal user. It's only interesting for testing purpose if I recall
correctly. And the patch that automatically set CONFIG_BUILD_ELF64
should fix this.

BTW, you should take a look at:

http://marc.info/?l=linux-mips&m=117019833420946&w=2

this thread clearly state that current config of IP32 kernel is
broken. Sorry for remembering so lately...
