Subject: [RFC PATCH 6/7] target/i386/kvm: Simplify kvm_get_mce_cap_supported()
Date: Tue, 23 Jun 2020 12:50:51 +0200 [thread overview]
Message-ID: <20200623105052.1700-7-philmd@redhat.com> (raw)
In-Reply-To: <20200623105052.1700-1-philmd@redhat.com>
As the MCE supported capabilities should be the same for
all VMs, it is safe to directly use the global kvm_state.
Remove the unnecessary KVMState* argument.
