However calling into the allocator from that IPI path seems very heavy weight. I will discuss with fellow engineers on how to fix it properly.Isn't the IPI code something that is likely to get called when a lot of stack has already been used? So you really shouldn't be using much stack at all??
I don't follow your questions. I don't dispute there is a problem. I just think calling into the allocator is not a good idea in that particular piece of code we need to fix. Hopefully we can come up with a solution to remove need for a cpumask in that code -- discussion is on-going. Wei.
