Subject: [PATCH for-5.1 0/3] target/arm: MTE improvements
Date: Mon, 13 Jul 2020 14:33:38 -0700	[thread overview]
Message-ID: <20200713213341.590275-1-richard.henderson@linaro.org> (raw)

Since MTE is new, and guest support for MTE is still under
development, let's disable it by default.

Peter mentioned memory hotplug on IRC as something that
would break MTE's assumptions.  By putting the enable flag
on the machine it's much easier to control.

For 5.1, we won't have kvm support, so error for that combo.
