1. Balloon driver does not need to set M2P entry.
This is done by the populate_physmap hypercall.
2. Xen now translates foreign mappings from GMFN->MFN.
Tools are simplified because of this.

Actually the conflict between LAPIC ID 0x00 and IOAPIC ID 0x00
really doesn't matter even in a native system but we can avoid
any risk of a warning by shifting the LAPIC ID space by one.
Also the changeset fixes construction of the MADT (LAPIC info
was overwriting the IOAPIC info) so we can now boot with ACPI
MADT again.

In fdctrl_start_transfer the sector size field (fifo[5]) is not
checked for overflows. This allows an arbitrarily large sector size
to be used, which can in turn result in a negative data_len field that
is then used for DMA transfers.
This can lead to the corrpuption of qemu state because some subsequent
checks on the transfer length is conducted using signed integers.
This patch limits the value fifo[5] to 7 which is the standard limit
on floppy sector size.

Older x86_64 linux kernels use one l4 table per cpu and context switch by
changing an l4 entry pointing to an l3 table. If we're shadowing them
we need to pin l3 shadows to stop them being torn down on every
context switch. (But don't do this for normal 64bit guests).

Chain hash buckets through the shadow page_info structs instead
of in separately allocated structures. This lets us get rid of
some xenheap allocations and a domain_crash_synchronous() call.

This does not work reliably across gcc versions. Workaround this by attaching
the regparm attribute to a variable instead.
Also since guest_to_host_gpr_switch() updates the guest EAX on the stack there
is no need to do so in emulate_privileged_op() as well. Therefore io_emul stub
now returns void.

1. Override ISA IRQs 5,6,10,11 as active-low level-triggered.
These are 'wired' to PCI devices.
2. Limit PCI-ISA link routers to route to 5,6,10,11. Others
are active-high edge-triggered and so invalid to use for
PCI devices. In any case, four ISA IRQs is sufficient to
avoid unnecessary aliasing among four links.
Also remove PCI device 0 IRQ info. It's an embedded host bridge with
no interrupt sources.

The Xen IPI spec states that destroy, hard_shutdown, pause, resume, start, suspend, and unpause return void. This patch makes it so and permits proper parsing of the response by clients (libxen) that follow the spec.
