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.
