     arm64-mte-make-mte_save_tags-and-mte_restore_tags-static.patch

Subject: arm64: mte: make mte_save_tags() and mte_restore_tags() static
Date: Tue, 08 Sep 2026 11:16:36 -0400

mte_save_tags() and mte_restore_tags() are only used by
arch_prepare_to_swap() and arch_swap_restore() in mteswap.c.  Make them
static and remove their declarations from mte.h.

No functional change.
