shadow_get_and_create_l1e() has tried to resync a page, but somehow we
weren't unable to remove the shadow (the real bug we should actually
look after). sh_resync() then removes the page from the OOS hash and
later in the page fault path we find the gw.l1mfn to be still OOS, so

ia64: PV driver domains - ugly python hacks
x86 IOMMU support added a lot of assumptions about what PCI buses look
like and where to find bridge devices. On ia64, we don't yet have
virtualization friendly IOMMUs, so for the moment, we just want to
keep "unsafe" PV PCI pass through working as well as it did in Xen
3.2. Looking at the code, it almost seems like x86 has thrown out
support for the old style driver domain. Things that don't
necessarily work on every PCI compliant architecture:
* You can't assume that just because there's a device at 01:01.0
that there's also a bridge at 01:00.0 and blow-up when you
don't find it. On HP ia64 boxes, PCI root bridges are not
necessarily exposed as a PCI device. This pretty much means
we can't call into any of the "FLR" code paths.
* BAR alignment: it's hard to have BAR alignment when your page
size is 16k. This wasn't a requirement for previous PV driver
domains, so I assume it's only for IOMMU support.
This is ugly, so I'm open to suggestions. It seems that all of these
architecture checks could be replaced by checking some "iommu_present"
variable to test whether the extra requirements are necessary.

[IA64] Cleanup ACPI checksum warnings
On bootup, I get a couple of these:
(XEN) ACPI Warning (tbutils-0219): Incorrect checksum in table [APIC] - CE, should be 04 [
20070126]
(XEN) ACPI Warning (tbutils-0219): Incorrect checksum in table [APIC] - CE, should be 04 [
20070126]
I don't remember seeing them before, but they're pretty easy to fix.
The problem is we update the lsapics, causing the checksum to be wrong,
then we look for platform interrupt sources, which spits out a warning,
and finally we look for the MADT again to fix the checksum, which also
prints a warning. If we grab a pointer to the MADT before these, we can
update the checksum after each step and avoid the warnings.

[IA64] Fix PV driver domains - xen stubs
Stub out new hypercalls in the hypervisor. The only odd one here is
map/unmap_pirq. This seems to be for MSI support, which I don't believe
we currently support for driver domains, so this is actually similar to
the x86 code path. The tools code doesn't allow us to return -ENOSYS
here :(

[IA64] allocate percpu area in the xen va area.
To guarantee that the percpu is pinned down,
move its virtual address from the xen identity mapped area
to the xen va area which is pinned by DTR[IA64_TR_KERNEL].
Then unnecessary tlb miss fault will be avoided.
Sometimes per cpu area is accessed from very critial
point where tlb miss isn't allowed.
