But what I sent out previously is not going into 2.6.40 anyway. Ingo
feels that it's too late in the merge window to pull those changes and
wants to wait till the next merge window. Since there's some fixes in
that pull request, I'll need to cherry pick them out and rebase the rest
for the next window.

Sorry to hear all of that.  This fix is needed in mainline.

Hmm, it is a warning fix. Well, I could add this to the cherry picking
I'm doing (fixes only).

I'm currently making a fix for a triple fault in the function tracer
caused by PROVE_RCU causing recursive tracing. When I get this fixed,
I'll be pushing the "fixes" next.

Actually it's more than a compile warning fix.

After a variable is cast from u64 to u32 and passed to __print_symbolic(),
we'll see incorrect result in the trace output.
