KVM: x86 emulator: limit instructions to 15 bytes
commit eb3c79e64a70fb8f7473e30fa07e89c1ecc2c9bb upstream
[ <cebbert@redhat.com>: backport to 2.6.27 ]
While we are never normally passed an instruction that exceeds 15 bytes,
smp games can cause us to attempt to interpret one, which will cause
large latencies in non-preempt hosts.
