...because the default timesource (TSC) drifts under load.
The flag is only defined in ACPI 3.0, and we provide ACPI 2.0 tables,
but Windows seems happy enough to obey it anyway.

When graphics card is assigned to a guest as a secondary VGA,
without gfx_passthru and emulated VGA is the primary VGA,
hvmloader misreads gfx_passthru is specified if VGA device is
found after the emulated VGA.
This patch fix this issue. If emulated VGA is found, hvmloader
preserves it and loads vgabios of the emulated VGA.

Fix an ACPI asl bug by explicitly convert PRS to buffer, otherwise PRS

Move processor from \_PR to \_SB. ACPI processor can be defined
under \_PR or \_SB. However, recently os like linux 2.6.30/32 support
cpu hotplug better for \_SB processor object.

Make build.c dependency on ssdt_{pm,tpm}.h explicit, else they can be
built in the wrong order.
Also, improve naming of target DSDT structures, and specify -p option
to iasl so that all generated files for a given target have
target-unique names, hence build can proceed safely in parallel.

In order to support HVM vcpu add/remove, we need set dsdt
infrastructure.
-- By using mk_dsdt.c, it auto-produce related asl code when
compiling.
-- It define processor related objects and control methods (_MAT,

-- It also define GPE _L02 and Notify control method for SCI

- Originally the max vcpu number for HVM guest is 32, this patch
extend the number to 128 on x86_64 hypervisor. (For i386 hypervisor,
the max vcpu number is still 32).
- This patch extends the mp-table size to fit more vcpus.
- HVM PV driver should call VCPUOP_register_vcpu_info hypercall to
initialize the vcpu info if the vcpu number is more than 32.
