select: add a poll specific struct to the restart_block union
with hrtimer poll/select, the signal restart data no longer is a single long representing a jiffies count, but it becomes a second/nanosecond pair that also needs to encode if there was a timeout at all or not. This patch adds a struct to the restart_block union for this purpose Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>
