domains with PV drivers loaded. This patch creates a new PV-on-HVM
module, reboot.ko, which, when loaded, creates control/reboot_module
in the store. The tools notice this, and disable the watch which would
normally destroy HVM domains which are the target of an xm shutdown
command, allowing the reboot module to shut the domain down cleanly.

It implements all registers necessary to make the Linux TIS driver
work (tpm_tis.c). All of the basic registers supported by this type of
device are implemented. Also the locality selection has been
implemented, but has not been tested. The legacy registers as
described in the specification are not supported.
Current caveat: The device has so far not yet been integrated with the
virtual TPM available in the repository. It will require changes to
the virtual TPM spawned by the vTPM manager to offer an additional message
interface. The TIS interface itself then needs to have an additional
transport implemented. (see vTPMTransmit array).
The relevant specification for the device model can be found here:

device of a certain type
- read the content of a variable related to a device, i.e.,
hotplug-status
- subscribe to changes of the hotplug status of a device for not
having to poll the status

As a program that runs in dom0 which serves users from guests,
the qemu drivers need to be vigilant to the input that comes
from the guests since they may be malicious.
As it is there are multiple ways to get ne2000 to read/write
memory beyond the 48K buffer that it has allocated for each
adapter.
This patch checks the addresses and prevents this from occuring.
The boundary is checked each time since it's changed for every
packet received while the other parameters are only changed
(by the guest) during setup.

We found Vista polls ACPI timer very frequently (about 15 times
averagely) when handling timer (RTC @ 64HZ) interrupt routine. Though
the exact reason is known, it should be related to system time
adjustment. When it's in Qemu, the overhead is big. After moving,
Vista's idle overhead decreases dramatically from ~10% to 0.9%.=20
Another benefit is that Vista can only pass Performance rating with
this patch. The root cause is that ACPI timer in Qemu isn't
synchronous with other platform timer in HV, which results in Vista
complains "can't measure TSC frequency".
This patch changes vpit.h to vpt.h, for it not only has pit structure
in it, but other platform timer's structure. Another change is moving
ACPI timer and related address from acpi.h to ioreq.h, which can be shared
by HV and ACPI firmware.
