Subject: target/arm: Use kvm_arm_sve_supported in kvm_arm_get_host_cpu_features
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0dd14e9555225a2b1f56ccdab5eb99d1684869b9;p=qemu.git

target/arm: Use kvm_arm_sve_supported in kvm_arm_get_host_cpu_features

Indication for support for SVE will not depend on whether we
perform the query on the main kvm_state or the temp vcpu.
