le64_to_cpu() was applied twice to the physical addresses read from the
control area. This hasn't shown any visible regressions because CRB
driver has been tested only on the little endian platofrms so far.

tpm_ibmvtpm_probe() calls ibmvtpm_reset_crq(ibmvtpm) without having yet
set the virtual device in the ibmvtpm structure. So in ibmvtpm_reset_crq,
the phype call contains empty unit addresses, ibmvtpm->vdev->unit_address.

Pull xen features and fixes from David Vrabel:

 - use a single source list of hypercalls, generating other tables etc.
   at build time.

 - add a "Xen PV" APIC driver to support >255 VCPUs in PV guests.

 - significant performance improve to guest save/restore/migration.

 - scsiback/front save/restore support.

 - infrastructure for multi-page xenbus rings.

 - misc fixes.

Originally Xen PV drivers only use single-page ring to pass along
information. This might limit the throughput between frontend and
backend.

The patch extends Xenbus driver to support multi-page ring, which in
general should improve throughput if ring is the bottleneck. Changes to
various frontend / backend to adapt to the new interface are also
included.

Affected Xen drivers:
* blkfront/back
* netfront/back
* pcifront/back
* scsifront/back
* vtpmfront

The interface is documented, as before, in xenbus_client.c.

In case the driver is configured to use irq, we are not waiting the answer
for a duration period to see the DATA_AVAIL status bit to raise but at
maximum timeout_c. This may result in critical failure as we will
not wait long enough for the command completion.

Make the tpm_infineon driver define its PM callbacks through
a struct dev_pm_ops object rather than by using legacy PM hooks
in struct pnp_driver.

This allows the driver to use tpm_pm_suspend() as its suspend
callback directly, so we can remove the duplicated savestate code.

I got a lot of requests lately about whether the new TPM2.0 support
includes the FIFO interface for TPM2.0 as well.
The FIFO interface is handled by tpm_tis since FIFO=TIS (more or less).
