Some Atari hardware has no capacity to raise interrupts (e.g.
network or USB adapter hardware attached via ROM port). The driver
interrupt routine is called from a timer interrupt (timer D) in
these cases, using chained device specific pseudo interrupts
(IRQ_MFP_TIMER1 ff.)
These interrupts will more often than not, return IRQ_NONE as
there is not always work for the device handler when called.
Too many unhandled interrupts will result in the interrupt
being disabled by the stuck interrupt watchdog.
As preferred option to flag interrupts as needing exclusion
from the watchdog mechanism, tglx added the IRQ_IS_POLLED flag
for use in such a case. Currently, two interrupts need to use
this flag. Add more users as needed.
This patch obsoletes the introduction of handle_polled_irq()
in the m68k tree.

when I'm talking to journalists I just say "programmer" or something like that.
