RE: [PATCH] remove bogus double softirq processing in cris

[Mikael Starvik]

Go ahead and submit it. This was removed locally quite a while ago and I'm
rewriting the IRQ handling to use the new consolidate IRQ stuff in 2.6.10 as
I write this. So don't bother that your patch breaks CRIS in the current 2.6
tree.

ping?  the broken code this patch removes really gets in the way of the
softirq_pending() removal I plan to submit soon..
