Merge branch 'uapi-Add-a-new-header-for-time-types'

Deepa Dinamani says:

====================
uapi: Add a new header for time types

The series aims at adding a new time header: time_types.h.  This header
is what will eventually hold all the uapi time types that we plan to
leave across the interfaces after the y2038 cleanup.

The series was discussed with Arnd Bergmann.

The second patch fixes the errqueue.h header, which has a dependency on
these types.

Note that there may be a trivial merge conflict with linux-next
c70a772f ("y2038: remove struct definition redirects").
