Since these instructions are documented to take their intercepts
before these checks are being done in hardware, they must be carried
out in software.

This is now the full set of changes needed to eliminate the assumption
that segments in protected mode always have zero base addresses. At
once, this further simplifies the instruction length determination
code used for MMIO of HVM domains.

- rdmsr/wrmsr always use ECX (not RCX) as register index.
- SVM still had the function names explicitly in the HVM_DBG_LOG() output
- the guest should (at the very minimum) see GP fault for MSRs
accesses to which even fault in Xen itself

Also simplify the HVM builder interface by doing more work in
the python wrapper, and fix mapping of shared_info page after the
change to map foreign pages by GMFN rather than MFN.

Add a resumed domain to the self.domains list after XendCheckpoint.restore,
to ensure that it does not get recreated immediately afterwards.
Perform domain_resume under the domains_lock, given that the domain needs to
be added.
These fixes together should fix xm suspend and xm resume.

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.
