x86: put timer_rand_state pointer into irq_desc
irq_timer_state[] is a NR_IRQS sized array that is a side-by array to the real irq_desc[] array. Integrate that field into the (now dynamic) irq_desc dynamic array and save some RAM. v2: keep the old way to support arch not support irq_desc Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
