vdso_time_data is not cacheline aligned at the moment. When instantiating an array, the start of the second array member is not cache line aligned. This increases the number of the required cache lines which needs to be read when handling e.g. CLOCK_MONOTONIC_RAW, because the data spawns an extra cache line if the previous data does not end at a cache line boundary. Therefore make struct vdso_time_data cacheline aligned.
