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.
