The usec part of the timeval is defined as
__kernel_suseconds_t tv_usec; /* microseconds */
Arnd noticed that sparc64 is the only architecture
that defines __kernel_suseconds_t as int rather than long.
This breaks the current y2038 fix for kernel as we only
access and define the timeval struct for non-kernel use cases.
But, this was hidden by an another typo in the use of __KERNEL__
qualifier.
Fix the typo, and provide an override for sparc64.
Fixes: 152194fe9c3f ("Input: extend usable life of event timestamps to 2106 on
32 bit systems")
