Wording suggestion:
If the patched function has a bug, it might cause serious side effects
like a kernel crash.

OK, I will try to optimize my description after the patch is reviewed. I am
sure there are something still need to be fix for that patch.

The only key that should wake up the phone is power button press. This
prevents accidental wakeup due to e.g. pressing the buttons in the
pocket or backpack and is in line what userspace uses to unblank the
device.

Flush to guarantee no workers are running when suspend returns,
for vdpa, vdpa_sim, and vduse. (mlx5 already does so, via the path
mlx5_vdpa_suspend -> unregister_link_notifier -> flush_workqueue.)
Changes in V2:
- renamed "vduse: suspend" (was vduse: flush workers on suspend)
- call vhost_de
Support the suspend operation. There is little to do, except flush to
guarantee no workers are running when suspend returns.

Flush to guarantee no workers are running when suspend returns.
Add a lock to enforce ordering between clearing running, flushing,
and posting new work in vdpasim_kick_vq. It must be a spin lock
because vdpasim_kick_vq may be reached va eventfd_write.

Hi Yuanchu,
kernel test robot noticed the following build errors:

Steal time feature is added here in kvm side, VM can search supported
features provided by KVM hypervisor, feature KVM_FEATURE_STEAL_TIME
is added here. Like x86, steal time structure is saved in guest memory,
one hypercall function KVM_HCALL_FUNC_NOTIFY is added to notify KVM to
enable the feature
Para-virt feature steal time is added in both kvm and guest kernel side.
It is silimar with other architectures, steal time structure comes from
guest memory, also pseduo register is used to save/restore base address
of steal time structure, so that vm migration is supported also.

Percpu struct kvm_steal_time is added here, its size is 64 bytes and
also defined as 64 bytes, so that the whole structure is in one physical

When vcpu is onlined, function pv_enable_steal_time() is called. This
