The part_event_bitmap register is 64 bits wide, so read it with ioread64() instead of the 32-bit ioread32().

This is the same patch but uses readq() which should be equivalent.Now queued up, thanks.
Hey Logan, As Guenter has pointed out, readq() is only defined for 64 bits, so this breaks compilation in i386. I've dropped this backport for now, if you could fix it up we could queue it up again. -- Thanks, Sasha
