sysv: Define __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64
On y2038 safe 32-bit systems the Linux kernel expects itimerval and rusage to use a 32-bit time_t, even though the other time_t's are 64-bit. There are currently no plans to make 64-bit time_t versions of these structs. There are also other occurrences where the time passed to the kernel via timeval doesn't match the wordsize. To handle these cases let's define a new macro __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64. This macro specifies if the kernel's old_timeval matches the new timeval64. This should be 1 for 64-bit architectures except for Alpha's osf syscalls. The define should be 0 for 32-bit architectures and Alpha's osf syscalls.
