[PATCH v2 06/10] sh: drop include/asm/mmzone.h

From: Mike Rapoport

Date: Sun May 10 2026 - 09:58:09 EST

From: "Mike Rapoport (Microsoft)" <rppt@xxxxxxxxxx>

include/asm/mmzone.h was required for declarations of NUMA related
functionality.

The only function declared there that's not related to NUMA is
__add_active_range().

Move __add_active_range() declaration to include/asm/setup.h and drop
include/asm/mmzone.h
