What's the plan for the class of PATA controllers without Device Control
shadow registers?
There are multiple examples of such in drivers/ide...
I ACK the patch's content, but don't forget we definitely need a plan
for PATA controllers without nIEN support.
I can't think of any solution other than ack'ing and clearing interrupts
blindly while frozen.
* it only happens from the freezing point until the device/controller is
reset.
* we can't detect spurious interrupts during that period but nothing
else is lost. Also, please note that most traditional IDE controllers
tend to have their own IRQ.
