Subject: [PATCH 4.4 31/48] KVM: x86: remove eager_fpu field of struct kvm_vcpu_arch
Date: Thu, 18 Oct 2018 19:55:06 +0200	[thread overview]
Message-ID: <20181018175429.615288507@linuxfoundation.org> (raw)
In-Reply-To: <20181018175427.133690306@linuxfoundation.org>

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paolo Bonzini <pbonzini@redhat.com>

commit 5a5fbdc0e3f1159a734f1890da60fce70e98271d upstream.

It is now equal to use_eager_fpu(), which simply tests a cpufeature bit.
