Building for 64bit kernel with 32bit ELF format produces the correct object files for loading, but attempting to load them produces ENOEXEC. This is because the object file is failing ELF header checks in load_module(). Elf_Ehdr in include/asm-mips/module.h is being defined as Elf64_Ehdr based on CONFIG_MIPS64 instead of CONFIG_BUILD_ELF64. elf_check_arch() also needs some fixing in include/asm-mips/elf.h as it too is invoked from load_module(), however elf_check_arch() is also used in binfmt_elf*.c. Simply changing the defines produces loads of warnings due to casting pointers around in module.c. Any suggestions on the best way to fix this? -- Dave Johnson Starent Networks
