Subject: [RFC PATCH 2/2] glibc: re-enable memory tagging
Date: Tue, 22 Jun 2021 17:24:59 +0100	[thread overview]
Message-ID: <20210622162459.1449458-2-ross.burton@arm.com> (raw)
In-Reply-To: <20210622162459.1449458-1-ross.burton@arm.com>

Now that the performance regressions caused by MTE have been resolved, we
can enable memory tagging again.

It is safe to globally enable the config as glibc does nothing if it isn't
supported on that target.
