[PATCH 00/11] Convert the posix_clock_operations and k_clock structure to ready for 2038

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().

Baolin Wang (11):
linux/time64.h:Introduce the 'struct itimerspec64' for 64bit
timekeeping:Introduce the current_kernel_time64() function with
timespec64 type
time/hrtimer:Introduce hrtimer_get_res64() with timespec64 type for
getting the timer resolution
posix timers:Introduce the 64bit methods with timespec64 type for
k_clock structure
time/posix-timers:Convert to the 64bit methods for k_clock callback
functions
char/mmtimer:Convert to the 64bit methods for k_clock callback
function
time/alarmtimer:Convert to the new methods for k_clock structure
time/posix-clock:Convert to the 64bit methods for k_clock and
posix_clock_operations structure
cputime:Introduce the cputime_to_timespec64/timespec64_to_cputime
function
time/posix-cpu-timers:Convert to the 64bit methods for k_clock
structure
k_clock:Remove the 32bit methods with timespec type
