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.
