Yes, it's still happening with next-20170607.
For me, `make oldconfig` hasn't changed it to CONFIG_VFIO_SPAPR_EEH=y. See:
$ git clean -dfxq
$ git reset --hard origin/master
HEAD is now at 8d1b80c Add linux-next specific files for 20170607
$ curl http://kisskb.ellerman.id.au/kisskb/buildresult/12982362/config/ -o .config
$ grep -E 'EEH|SPAPR' .config
CONFIG_EEH=y
# CONFIG_SPAPR_TCE_IOMMU is not set
$ yes '' | make oldconfig
$ grep -E 'EEH|SPAPR' .config
CONFIG_EEH=y
# CONFIG_SPAPR_TCE_IOMMU is not set
$ make -j 160 ARCH=powerpc
