[PATCH 0/4] [y2038] clock_settime for timespec64

[PATCH 0/4] [y2038] clock_settime for timespec64

[chensong]

This patch serial is aimed to introduce a new syscall clock_settime64,
which is specific for 64-bit time_t.

There is no impact to current implemetation of clock_settime, nothing
broken.

  [y2038]cobalt: posix: clock: Adding clock_settime64
  [y2038]cobalt: posix: syscall32: Adding compat clock_settime64

This patch is not necessary. We don't care about the 4.4 kernel (the
only one which does not provide this data types) as it has no y2038
syscalls at all.

This two patches should be squashed. No need to separate the compat
syscall. Some inline comments will follow

Will comment on this patch separately.
