Bitmaps are rather scalable, we use them all around the place.
Erm, IDA/IDR uses a bitmap ...
IDA is a dynamically allocated bitmap - but for something as critical as
IRQs i'd rather like to see a preallocated bitmap and platform control
over the max (nr_irqs). We dont want to allow crappy drivers to install
irq 0x12345678 and blow up the bitmap size to dozens of MB, etc.
Bitmaps are simple - and that's a virtue.
