* The driver has been modified to enable interrupts a bit more: in order to

* worst that can happen is that an unexpected HD-interrupt comes in and
* sets the "reset" variable and starts the timer)
* The driver enables interrupts as much as possible. In order to do this,
* (a) the device-interrupt is disabled before entering hd_request(),
* and (b) the timeout-interrupt is disabled before the sti().
*
* Interrupts are still masked (by default) whenever we are exchanging
* data/cmds with a drive, because some drives seem to have very poor
* tolerance for latency during I/O. For devices which don't suffer from
* that problem (most don't), the unmask_intr[] flag can be set to unmask
* other interrupts during data/cmd transfers (by defining DEFAULT_UNMASK_INTR
* to 1, or by using "hdparm -u1 /dev/hd?" from the shell).
