Hi Rafael,
__cpufreq_driver_target() must not pass target frequency beyond the limits of

I wanted to get your opinion on this before making changes

MPS tables are not needed for systems that have proper ACPI support.
This is also true for systems that have SFI in place.
So this patch is to exclude X86_MPPARSE when either ACPI or SFI is present.

If the target is x86/x86_64, the guest's kernel will write 0x01 to the
port KVM_PV_EVENT_PORT when it is panciked. This patch introduces a new
qom device kvm_pv_ioport to listen this I/O port, and deal with panicked
event according to panicked_action's value. The possible actions are:

We can know the guest is panicked when the guest runs on xen.
But we do not have such feature on kvm.
Another purpose of this feature is: management app(for example:
libvirt) can do auto dump when the guest is panicked. If management
app does not do auto dump, the guest's user can do dump by hand
update kernel headers to add pv event macros.
