KVM: x86 emulator: disable writeback for TEST The TEST instruction doesn't write its destination operand. This could cause problems if an MMIO register was accessed using the TEST instruction. Recently Windows XP was observed to use TEST against the APIC ICR; this can cause spurious IPIs. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
