[PATCH v5 00/24] Convert the posix_clock_operations and k_clock structure to ready for 2038

[Baolin Wang]

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.
