Subject: [PATCH v14 3/8] arm64: mte: Drop arch_enable_tagging()
Date: Mon, 8 Mar 2021 16:14:29 +0000 [thread overview]
Message-ID: <20210308161434.33424-4-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20210308161434.33424-1-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.
