The __suseconds64_t type is supposed to be the 64 bit type across all
architectures.

It would be mostly used internally in the glibc - however, when passed to
Linux kernel (very unlikely), if necessary, it shall be converted to 32
bit type (i.e. __suseconds_t)

Please use consistent spacing (tab instead of spaces).
