struct timespec is being removed from the kernel because it often leads to code that is not y2038-safe. In the etnaviv driver, monotonic timestamps are used, which do not suffer from overflow, but the usage of timespec here gets in the way of removing the interface completely. Pass down the user-supplied 64-bit value here rather than converting it to an intermediate timespec to avoid the conversion. The conversion is transparent for all regular CLOCK_MONOTONIC values, but is a small change in behavior for excessively large values: the existing code would treat e.g. tv_sec=0x100000000 the same as tv_sec=0 and not block, while the new code it would block for up to 2^31 seconds. The new behavior is more logical here, but if it causes problems, the truncation can be put back.
