MIPS: Provide correct siginfo_t.si_stime
Provide correct siginfo_t.si_stime on MIPS64
Bug description:
MIPS version of copy_siginfo() is not aware of alignment on platforms with
64-bit long integers, which leads to an incorrect si_stime passed to signal
handlers, because the last element (si_stime) of _sifields._sigchld is not
copied. If _MIPS_SZLONG is 64, then the _sifields starts at the offset of
4 * sizeof(int).
Patch description:
Use the generic copy_siginfo, which doesn't have this problem.
