If you'd spend more time reviewing IRQ patches then maybe you'd catch
this at review time. So please stop your rediculous whinging when
most of the problem is your own lack of time.

If you must know, it was introduced by TI to work around the power
management shortcomings of the architecture mandated GIC. No it doesn't
get called for IPIs, but it damned well needs to be called for normal

At the point it was created, it wasn't clear whether this also applied
to local IRQs. Since I *no* *longer* have visibility of what SoC stuff
is doing with it, of course it's not going to get fixed when a common
pattern emerges.

So... congratulations, you've found something which can be improved,
which has come to light as the code has evolved and a better
understanding of what is required has been discovered.
