[PATCH 0/6] Introduce 64bit accessors and structures required to address y2038 issues in the posix_clock subsystem

This patch series change the 32-bit time types (timespec/itimerspec) to
the 64-bit types (timespec64/itimerspec64), and add new 64bit accessor
functions, which are required in order to avoid y2038 issues in the
posix_clock subsystem.

In order to avoid spamming people too much, I'm only sending the first
few patches of the patch series, and left the other patches for later.

And if you are interested in the whole patch series, see:

Thoughts and feedback would be appreciated.
