[IA64] let VMM do itc sync for guest on VTI domain
Previously, on SMP VTI-domain, Guest OS was responsible for
syncing itc by calling ia64_sync_itc, but the round trip may
be very large on VTI domain, that may cause guest itcs are
not synced well and cause guest wall clock is not accurate.
This patch intends to fix this issue, when guest wants to sync

This option is assumed and not needed if the `usbdevice' option

This will enable USB and also enable support for the given device.
Currently, the only two devices are `mouse' (a PS/2 mouse) and
`tablet' (an absolute pointing device). The advantage of `tablet'
is that Windows guests will automatically recognize and support this
device so specifying the config line:
usbdevice='tablet'

under VNC. (Linux doesn't recognize the USB tablet yet so Linux

affinity via /proc is held until the next interrupt on that

Other notes:
1. CPU-specific interrupts silently ignore requests to change
affinity. For example, resched0, timer0, callfunc0, ...
2. Reading smp_affinity always returns a cpumask containing
a single cpu. An event channel can only be bound to a single
cpu at a time. Neither Xen nor XenLinux implement IRQ

[VMXASSIST] Extensions to vmxassist to handle additional mode switch cases.
Extends vmxassist to handle two cases related to mode switching found
while experimenting with different boot loaders.
The first case is use of the JMP instruction with memory location
operands to complete a switch to protected mode. This patch adds
emulation for this form of the JMP instruction to vmxassist.
The second case is where boot loader code does not save/restore a
non-zero SS register across a protected mode traversal.
Zeroing the SS register in vmxassist results in all sorts of problems
in the domU after returning back to real mode. This patch stores
segment register values before entering protected mode and correctly
restores the old values (instead of an incorrect zero value) when
reentering real mode.
