Sure thing. But this change actually causes regression in our in-house testing for
the arc700 defconfigs which falter due to missing CONFIG_ISA_ARCOMPACT which was
the default before. Alexey found this and will post a fixup whcih I plan to squash
into ur patch to keep bisectability (and allow trivial stable backports) and then
regen the relevant defconfigs.
