include/asm-generic/siginfo.h has

/* SIGCHLD */
struct {
__kernel_pid_t _pid; /* which child */
__ARCH_SI_UID_T _uid; /* sender's uid */
int _status; /* exit code */
__kernel_clock_t _utime;
__kernel_clock_t _stime;
} _sigchld;


Although x32 __kernel_clock_t is s64 with 64bit alignment, in
_sigchld, it must be compat_s64 with 32bit alignment.
