Subject: [PATCH] linux-user/aarch64: Enable hwcap for RND, BTI, and MTE
Date: Tue, 27 Apr 2021 14:41:08 -0700	[thread overview]
Message-ID: <20210427214108.88503-1-richard.henderson@linaro.org> (raw)

These three features are already enabled by TCG, but are missing
their hwcap bits.  Update HWCAP2 from linux v5.12.
