 While the usefullness of syscall(2) and __syscall(2) is unclear, and its
 use in sanitizer sounds like a bug, we should still make the kernel
 reject the invalid calls in syscall(2).
 
 Grepping through syscalls.master it would seem that we should have a
 
 	switch (code) {
 	case SYS_pwritev:
 	case SYS_mknodat:
 	case SYS_truncate:
 	case SYS_ftruncate:
 	case SYS_preadv:
 	case SYS_lseek:
 	case SYS_fsync_range:
 	case SYS_mmap:
 	case SYS_pwrite:
 	case SYS___posix_fadvise50:
 	case SYS_posix_fallocate:
 	case SYS_pread:
 	case SYS_fdiscard:
 		return EINVAL;
 	}
 
 or similar, at least if emul == netbsd.
