You are using CONFIG_BUILD_ELF64=y and CKSEG0 load address.
This combination does not work.  Please refer these threads:

http://www.linux-mips.org/archives/linux-mips/2006-10/msg00064.html
http://www.linux-mips.org/archives/linux-mips/2006-10/msg00154.html
http://www.linux-mips.org/archives/linux-mips/2007-01/msg00305.html

Please try CONFIG_BUILD_ELF64=n.

BTW, Ralf, any chance to Franck's CONFIG_BUILD_ELF64 cleanup patchset?
I hope the patchset make things clearer...
