nics=4 can specify 4 vmx NIC now.

For self-migration, I need the ability to trap writes to the p2m map
during migration, because I keep a dictionary mapping mfns to pfns,
which I use for remapping the page tables once I am on the other side.

When sending IPI, the target vcpu may not be launched (like
INIT/Start-Up IPI), and the local apic is not initialized. Fix handling
on such case.
Also fix one bug in apic_round_robin function.

vmx_final_setup_guest, so in arch_set_info_guest, the phys_basetab
is not do get_page, while when destroying, put_page is called,
so there is one page, the count=-1, and when a new domain allocate
this page, it will take it as cpumask 0xffffffff, this cause flash_tlb_mask
goes into dead loop.
This patch also eliminate the warning when creating vmx guest:

ia64/VTI. Now ia64/vti will create links to arch/x86/dm/vmx_vioapic.c
and include/x86/vmx_vlapic.h.
Firstly, a small change to common virtual IOAPIC model to be used by
both sides. Also some compilation fix to tools is included in first
one. Secondly, there are ia64-specific changes to hook to common
IOAPIC model.
Based on this patch upon latest xen-ia64-unstable tip, we can see
multiple domains working again on XEN/IA64, including both domU and
VTI domain simultaneously in run-time.

spare. Anyone with more than 8 NICs can still use the kernel command line or
the module parameter line to pass a larger limit to this module.
Detail the kernel command line parameter for nloopbacks in the diagnostic in
network-bridge.

Separate out the ability for domains to be able to write to their
pagetables (ala "writable page tables", which uses write-protected PTEs
to address the page tables: this is shadow_mode_write_all()) from the
right of a domain to create a PTE with write permissions that points
at a page table (this is shadow_mode_wr_pt_pte())...
Minor cleanup of SHADOW_DEBUG (at least make it compilable) in shadow.c.
