This patch adds a workaround for an IOMMU BIOS problem to
the AMD IOMMU driver. The result of the bug is that the
IOMMU does not execute commands anymore when the system
comes out of the S3 state resulting in system failure. The
bug in the BIOS is that is does not restore certain hardware
specific registers correctly. This workaround reads out the
contents of these registers at boot time and restores them
on resume from S3. The workaround is limited to the specific
IOMMU chipset where this problem occurs.

Add the xen pci platform device driver that is responsible
for initializing the grant table and xenbus in PV on HVM mode.
Few changes to xenbus and grant table are necessary to allow the delayed
initialization in HVM mode.
Grant table needs few additional modifications to work in HVM mode.

The Xen PCI platform device raises an irq every time an event has been
delivered to us. However these interrupts are only delivered to vcpu 0.
The Xen PCI platform interrupt handler calls xen_hvm_evtchn_do_upcall
that is a little wrapper around __xen_evtchn_do_upcall, the traditional
Xen upcall handler, the very same used with traditional PV guests.

When running on HVM the event channel upcall is never called while in
progress because it is a normal Linux irq handler (and we cannot switch
the irq chip wholesale to the Xen PV ones as we are running QEMU and
might have passed in PCI devices), therefore we cannot be sure that
evtchn_upcall_pending is 0 when returning.
For this reason if evtchn_upcall_pending is set by Xen we need to loop
again on the event channels set pending otherwise we might loose some
event channel deliveries.

As reported by Vernon Mauery <vernux@us.ibm.com>, X5670 (Westmere-EP) uses a
different register for one of the uncore PCI devices. Add support for
it.

Those are the PCI ID's on this new chipset:

fe:00.0 0600: 8086:2c70 (rev 02)
fe:00.1 0600: 8086:2d81 (rev 02)
fe:02.0 0600: 8086:2d90 (rev 02)

fe:06.3 0600: 8086:2db3 (rev 02)
(as usual, the same PCI devices repeat at ff: bus)

The PCI device 8086:2c70 is shown as:

fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic
Non-core Registers (rev 02)

So, for this device to be recognized, it is only a matter of adding this
new PCI ID to the driver.

Xeon55xx fails to probe with this error message:

i7core_edac: probe of 0000:00:14.0 failed with error -22

PCI ID 8086:2c40.

This code changes the detection procedure of i7core_edac. Instead of
directly probing for MC registers, it probes for another register found
on Nehalem. If found, it tries to pick the first MC PCI BUS. This should
work fine with Xeon 35xx, but, on Xeon 55xx, this is at bus 254 and 255
that are not properly detected by the non-legacy PCI methods.

The new detection code scans specifically at buses 254 and 255 for the
Xeon 55xx devices.

This code has not tested yet. After working, a change at the code will
be needed, since the i7core is not yet ready for working with 2 sets of
MC.

The public Intel Xeon 5500 volume 2 datasheet describes, on page 53,
session 2.6.7 a register that can lock/unlock Memory Controller the
configuration register, called MC_CFG_CONTROL.

Adds support for it in the hope that software error injection would
work. With my tests with Xeon 35xx, there's still something missing.
With a program that does sequencial bit writes at dev 0.0, sometimes, it
produces error injection, after unblocking the MC_CFG_CONTROL (and,
sometimes, it just locks my testing machine).

I'll try later to discover by trial and error what's the register that
solves this issue on Xeon 35xx.

This driver is meant to support i7 core/i7core extreme desktop
processors and Xeon 35xx/55xx series with integrated memory controller.
It is likely that it can be expanded in the future to work with other
processor series based at the same Memory Controller design.

For now, it has just a few MCH status reads.

IDs should generally only be added to pci_ids.h when they're shared

Perhaps documenting this is a good idea to prevent things being moved there,
as it still seems to be happening judging from the git log.
