I don't want to insist too much on it, but this is not correct. In the
process of shifting the patch to the right, something ate the leading
space on each patch context line. The patch is ill-formatted even if the
first tab is removed. Try to keep it simple and either attach it or post
it without any change whatsoever.

I mean I did suggest dynamic allocation for the array since my first
reply in this thread, which is essentially what the patch is..
Given that dynamic allocation was already mentioned and then you
suggested to replace NR_CPUS with something dynamic, I took that as an
alternative proposal and an invitation at using VLAs, which is what I
was commenting on, and what I was saying I don't think would work.

By VLAs I mean:
-	u16 channels[NR_CPUS];
+	u16 channels[num_possible_cpus()];

Anyway...
