for the RSDP in memory (up to the BIOS) rather than calculating its
start address. Recent changes seem to have moved the RSDP to another
location in memory so that I received 'BAD RSPD signature' messages.
I have also fixed some other possible issues related to return codes
and alignment of ACPI entries.

While the kernel side of blktap drivers is using 64-bit sector numbers
correctly when reporting disk sizing, the userspace parts where this
dat is actually generated is truncating at 32-bit. There are 3 variables
related to disk sizing which are used in the kernel/userspace code
'size', 'sector size' & 'info'. In kernel space these are treated as being
unsigned long long, unsigned long, and unsigned int, respectively. In
the blktap userspace code this were all varyingly long, unsigned long.
This mismatch caused 32-bit wraparound on large disks. The attached
patch updates the blktap userspace to use the same data types as
kernel space for all these params, thus both fixing the 32-bit bug &
giving the code consistency.
This patch has been tested both by comparing /proc/partitions in the
guest, with the image size seen in the host, and by using Stephen
Tweedie's 'verify-data' tool on a variety of multi-TB sized disks.

The default config read/write handlers allows a 4-byte read/write at
address 255. This can clobber the field after the config area. This
happens to be the PCIBus pointer in the PCIDevice structure.
This patch stops this from reducing the read/write to the (largest
multiple of 2) number of bytes within the config area.

equivalent to xend.domains_with_state(running). This restores the Xen 3.0.3
semantics of xend.domains.

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

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.
