Subject: [PATCH] target/arm: Flush correct TLBs in tlbi_aa64_vae2is_write()
Date: Tue, 20 Apr 2021 13:31:06 +0100	[thread overview]
Message-ID: <20210420123106.10861-1-peter.maydell@linaro.org> (raw)

In tlbi_aa64_vae2is_write() the calculation
  bits = tlbbits_for_regime(env, secure ? ARMMMUIdx_E2 : ARMMMUIdx_SE2,
                            pageaddr)

has the two arms of the ?: expression reversed. Fix the bug.
