2017-10-30	time: Move time_t conversion helpers to time32.h	Arnd Bergmann	1	-0/+45
	On 64-bit architectures, the timespec64 based helpers in linux/time.h are defined as macros pointing to their timespec based counterparts. This made sense when they were first introduced, but as we are migrating away from timespec in general, it's much less intuitive now. This changes the macros to work in the exact opposite way: we always provide the timespec64 based helpers and define the old interfaces as macros for them. Now we can move those macros into linux/time32.h, which already contains the respective helpers for 32-bit architectures.

2017-10-30	time: Move time_t based interfaces to time32.h	Arnd Bergmann	1	-0/+176
	Interfaces based on 'struct timespec' or 'struct timeval' should no longer be used for new code, which can use either ktime_t or 'struct timespec64' instead. To make this a little clearer, this moves the various helpers into a new time32.h header. For the moment, this gets included by the normal time.h, but we may be able to separate it entirely when most users of time32.h are gone. Individual helpers in the new file can get removed once they become unused in the future. Since the contents of time32.h look a lot like what's in time64.h, I'm reordering them during the move to make them more similar, and to allow a follow-up patch to redirect the 'timespec' based functions to thei 'timespec64' based counterparts on 64-bit architectures later.
