[PATCH v16 3/9] arm64: mte: Drop arch_enable_tagging()

From: Vincenzo Frascino
Date: Mon Mar 15 2021 - 09:21:19 EST


arch_enable_tagging() was left in memory.h after the introduction of
async mode to not break the bysectability of the KASAN KUNIT tests.

Remove the function now that KASAN has been fully converted.
