Message-Id: <53744fa2afeb19f0ce31cb109e0b3c1f1c8b815b@dist-git>

Subject: [PATCH] qemu: Make qemuMonitorGetGuestCPU usable on x86 only
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It was never implemented or used for anything else anyway. Mainly
because it uses CPUID features bits. The function is renamed as
qemuMonitorGetGuestCPUx86 to make this explicit.
