awilliam@xenbuild.aw 7d408ed38f [IA64] fixed a vcpu_translate bug 
There are some below code segments in guest OS
1.     Rsm psr.dt
       ...
2.     itc.d r18
       ...
3.     rfi

After executing instruction 1, domain is in metaphysical mode.
When executing instruction 2, VMM gets control to emulate this
instruction. Firstly VMM will try to get opcode, which may
trigger a tlb miss. At this time domain is in metaphysical mode
and the fault address is in region 5. vcpu_translate handles this
as normal guest metaphysical mode.

It's not correct; sometimes this will make dom0 hang.

cpu_translate should handle this situation as if
guest is not in metaphysical mode.

kaf24@firebug.cl.cam.ac.uk 7d258cc98e Add Summagraphics Tablet emulation for VNC users. The current PS/2 emulation 
is unusable under VNC since a PS/2 mouse provides deltas while VNC only

kaf24@firebug.cl.cam.ac.uk 3fd07d7995 Add a shadow VRAM to track changes to the real VRAM. When the guest 
OS was given write access to the VRAM the device model tracked all
VRAM changes by updating the entire screen on every output loop,
causing significant overhead (a CPU bound loop in a guest slows down
by about 35%) and significant mouse latency (VNC uses the same data
path for mouse events and video updates).  With the shadow VRAM only
modified pages need to be updated and the comparison of the shadow
VRAM to the real VRAM only adds ~4% overhead while eliminating the
mouse latencies.
