If it just added RESCTRL_NODE to the enum and the switch() I'd
agree (as patch 7 is where RESCTRL_NODE first used). But this
patch also adds the sanity checks on scope where it has to be
a cache level.

Patch 7 is already on the big side (119 lines added to core.c).

If you really think this series needs to cut back the
number of patches, I could move the sanity check pieces
from here to patch 3 (where the enum is introduced) and
just the RESCTRL_NODE bits to patch 7.
