Subject: [PATCH v16 3/9] arm64: mte: Drop arch_enable_tagging()
Date: Mon, 15 Mar 2021 13:20:13 +0000	[thread overview]
Message-ID: <20210315132019.33202-4-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20210315132019.33202-1-vincenzo.frascino@arm.com>

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.
