Subject: [RFC v14 75/80] target/arm: move arm_cpu_finalize_features into cpu64
Date: Fri, 16 Apr 2021 18:28:19 +0200
Message-ID: <20210416162824.25131-76-cfontana@suse.de> (raw)
In-Reply-To: <20210416162824.25131-1-cfontana@suse.de>

all the features in arm_cpu_finalize_features are actually
TARGET_AARCH64-only now, since KVM is now only supported on 64bit.

Therefore move the function to cpu64.
