compat_sys_migrate_pages no, you don't want compat_sys_rt_sigsuspend either. it's only for 64 bit systems runnign 32 bit user space, like all compat_sys_* calls. > /* kernel/sched.c */ > ok .long

sys_mmap2 should probably go to fs/pipe.c and mm/mmap.c, but that does not need to be your worry right now, it's not part of the ABI.
