This patch series changes the 32-bit time type (timespec/itimerspec) to the 
64-bit one
(timespec64/itimerspec64), since 32-bit time types will break in the year 2038.

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.

Also introduces some new functions with timespec64/itimerspec64 type, like 
current_kernel_time64(),
hrtimer_get_res64(), cputime_to_timespec64() and timespec64_to_cputime().

Changes since V1:
        -Split some patch into small patch.
        -Change the methods for converting the syscall and add some default 
function for new 64bit methods for syscall function.
        -Introduce the new function do_sys_settimeofday64() and move 
do_sys_settimeofday() function to head file.
        -Modify the EXPORT_SYMPOL issue.
        -Add new 64bit methods in cputime_nsecs.h file.
        -Modify some patch logs.
