| Message-ID | <rNZSp-8pa-3@gated-at.bofh.it> |
Minor cleanups for CONFIG_ZONE_DEVICE.
Andrew, killing the CONFIG_EXPERT dependency might be worth applying for
4.7, but otherwise these can wait for 4.8. These have received a "build
success" notification from the kbuild robot over 58 configs. Please
apply, or ack and I'll queue them with the rest of the libnvdimm-for-4.8
updates.

When it was first introduced CONFIG_ZONE_DEVICE depended on disabling CONFIG_ZONE_DMA, a configuration choice reserved for "experts". However, now that the ZONE_DMA conflict has been eliminated it no longer makes sense to require CONFIG_EXPERT.
