The x86 platform operations are fairly isolated, so it's easy to change them from using timespec to timespec64. It has been checked that all the users and callers are safe, and there is only one critical function that is broken beyond 2106: pvclock_read_wallclock() uses a 32-bit number of seconds since the epoch to communicate the boot time between host and guest in a virtual environment. This will work until 2106, but fixing this is outside the scope of this change, Add a comment at least.
