When building for x86-32 the ptregs_checkpoint and ptregs_restart definitions are missing because they're surrounded by arch/x86/built-in.o: In function `sys_call_table': (.rodata+0x58c): undefined reference to `ptregs_checkpoint' arch/x86/built-in.o: In function `sys_call_table': (.rodata+0x590): undefined reference to `ptregs_restart' The solution is to map these to sys_checkpoint from kernel/sys_ni.c when CONFIG_CHECKPOINT is not defined.
