     Please put this into the separate patch and push thru the PPC tree.

I agree to put to them to separate patches, but should we
pull in the separate patches to one candidate tree to make
the function work?

    I don't understand. What is "candidate tree"?

Powerpc or ide git repository for upstream to mainline.
It is odd that patches for one function in different trees.
Thanks.
