Wasn't there a plan to make CONFIG_IRQSTACKS the unconditional
default?
Not sure. Looks like the 64-bit configs all turn it on, and all but
one
or two of the 32-bit configs don't.
Yeah, but do they have a reason not to turn it on? Having irqstacks
is a lot safer than no having it because the stack useage is a lot
more
predictable. And not having to maintain two codepathes is also a
benefit all by itself.
I think Ben, Paul and I had discussed just universally enabling it.
Can't remember why Ben hadn't done that yet.
