If an o32 process generates a core dump on a 64 bit kernel, the core file will not be correctly recognized. This is because ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use the default register set which would be CONFIG_64BIT in asm/elf.h. So we'll switch to use the right register defines in this situation by checking for WANT_COMPAT_REG_H and use the right defines of ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS. [Ralf: made ELF_CORE_COPY_TASK_REGS() bullet-proof against funny arguments.] Signed-off-by: Yong Zhang <yong.zhang@windriver.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
