Dear Thiemo, Thanks for your quickly response. I try to modify the /arch/mips/ld.script.in or /arch/mips/kernel/head.S but still can't work (entry is changed but kernel can't work). Do I make any mistake?

The entry address is encoded in the ELF header at the beginning of vmlinux (as it is for all other ELF executables). The header's layout can be found e.g. in linux/include/linux/elf.h. Thiemo
