struct timeval is not y2038 safe. All usage of timeval in the kernel will be replaced by y2038 safe structures.
struct input_event maintains time for each input event. Real time timestamps are not ideal for input as this time can go backwards as noted in the patch a80b83b7b8 by John Stultz. Hence, having the input_event.time fields only big enough for monotonic and boot times are sufficient.
Leave the original input_event as is. This is to maintain backward compatibility with existing userspace interfaces that use input_event. Introduce a new replacement struct raw_input_event. This replaces timeval with struct input_timeval. This structure maintains time in __kernel_ulong_t or compat_ulong_t to allow for architectures to override types as in the case of x32.
The change requires any userspace utilities reading or writing from event nodes to update their reading format to match raw_input_event.The changes to the popular libraries will be posted along with the kernel changes. The driver version is also updated to reflect the change in event format.
