This patch series changes the 32-bit time types (timespec/itimerspec) to
the 64-bit types (timespec64/itimerspec64), since 32-bit time types will
break in the year 2038 on 32bit systems.
This patch series introduces new methods with timespec64/itimerspec64 type,
and removes the old ones with timespec/itimerspec type for posix_clock_operations
and k_clock structure.
---
Changes since v4:
- Rebase the patch series.
- Modify the subject line and the changelog.
Changes since v3:
- Fix some introducing bugs.
Changes since v2:
- Split the syscall conversion patch into small some patches.
Changes since V1:
- Split some patch into small patch.
- Add some default function for new 64bit methods for syscall function.
- Move do_sys_settimeofday() function to head file.
- Modify the EXPORT_SYMPOL issue.
- Add new 64bit methods in cputime_nsecs.h file.

Sigh. How is that better than the previous one? It's more accurate,
but equally useless.
And of course you did not address my request to change the macro mess
in

according to the discussion with Arnd.
Thanks,
