I did the revert in linux-stable (last tag being v4.3-rc4) gave a revert
description so it would be applied.

built and tested.  Result:  did not help, still missing the second core.

I am sure the revert happened but I am uncertain as to how to build in a
git tree.  I think I did it correctly
   cp .config into   linux-stable   tree
   edit Makefile to add -rev to: EXTRAVERSION = -rc4-rev
   make oldconfig
   make -j3 >> ../mak/mak_430-rc4-rev.log 2>&1 &

The before/after kernels are:
    3965280 Oct  4 15:20 vmlinuz-4.3.0-rc4
    3965408 Oct 15 13:45 vmlinuz-4.3.0-rc4-rev
The reverted vmlinuz is 128 bytes bigger;  .config's are identical.  I
see the revert adds back in some code so sizes seem appropriate.
