kvm: x86: disable shattered huge page recovery for PREEMPT_RT. If a huge page is recovered (and becomes no executable) while another thread is executing it, the resulting contention on mmu_lock can cause latency spikes. Disabling recovery for PREEMPT_RT kernels fixes this issue. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
