Subject: question about IRQF_IRQPOLL in clocksource driver

Hi All,

I found almost all the drivers under drivers/clocksource/*.c has
IRQF_IRQPOLL flag. I am not very sure what this flag used
for the drivers for ARM platforms.

I think this flag is not needed for ARM platforms, BTW I just
checked NXP i.MX driver. But not very sure, please share
your knowledge if you have time.

Thanks,
Peng.
