The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able
to dynamically set up MBus address decoding windows for PCI I/O and
memory regions depending on the PCI devices enumerated by Linux.

However, this emulated PCI-to-PCI bridge logic makes the Linux PCI
core believe that prefetchable memory regions are supported (because
the registers are read/write), while in fact no adress decoding window
is ever created for such regions. Since the Marvell MBus address
decoding windows do not distinguish memory regions and prefetchable
memory regions, this patch takes a simple approach: change the
PCI-to-PCI bridge emulation to let the Linux PCI core know that we
don't support prefetchable memory regions.

To achieve this, we simply make the prefetchable memory base a
read-only register that always returns 0. Reading/writing all the
other prefetchable memory related registers has no effect.

This problem was originally reported by Finn Hoffmann
<finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working
on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem
was that the PCI-to-PCI bridge emulation was making the Linux PCI core
believe that we support prefetchable memory, so the Linux PCI core was
only filling the prefetchable memory base and limit registers, which
does not lead to a MBus window being created. The below patch has been
confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has
otherwise been successfully tested on the Armada XP GP platform with a
e1000e PCIe NIC and a Marvell SATA PCIe card.

IPoIB's required behaviour w.r.t to the pkey used by the device is the following:

- For "parent" interfaces (e.g ib0, ib1, etc) who are created
  automatically as a result of hot-plug events from the IB core, the
  driver needs to take whatever pkey vlaue it finds in index 0, and
  stick to that index.

- For child interfaces (e.g ib0.8001, etc) created by admin directive,
  the driver needs to use and stick to the value provided during its
  creation.

In SR-IOV environment its possible for the VF probe to take place
before the cloud management software provisions the suitable pkey for
the VF in the paravirtualed PKEY table index 0. When this is the case,
the VF IB stack will find in index 0 an invalide pkey, which is all
zeros.

Moreover, the cloud managment can assign the pkey value at index 0 at
any time of the guest life cycle.

The correct behavior for IPoIB to address these requirements for
parent interfaces is to use PKEY_CHANGE event as trigger to optionally
re-init the device pkey value and re-create all the relevant resources
accordingly, if the value of the pkey in index 0 has changed (from
invalid to valid or from valid value X to invalid value Y).

This patch enhances the heavy flushing code which is triggered by pkey
change event, to behave correctly for parent devices. For child
devices, the code remains the same, namely chases pkey value and not
index.

Currently, QP1 is created using pkey index 0. This patch simply looks
for the index containing the default pkey, rather than hard-coding
pkey index 0.

This change will have no effect in native mode, since QP0 and QP1 are
created before the SM configures the port, so pkey table will still be
the default table defined by the IB Spec, in C10-123: "If non-volatile
storage is not used to hold P_Key Table contents, then if a PM
(Partition Manager) is not present, and prior to PM initialization of
the P_Key Table, the P_Key Table must act as if it contains a single
valid entry, at P_Key_ix = 0, containing the default partition
key. All other entries in the P_Key Table must be invalid."

Thus, in the native mode case, the driver will find the default pkey
at index 0 (so it will be no different than the hard-coding).

However, in SR-IOV mode, for VFs, the pkey table may be
paravirtualized, so that the VF's pkey index zero may not necessarily
be mapped to the real pkey index 0. For VFs, therefore, it is
important to find the virtual index which maps to the real default
pkey.

This commit does the following for QP1 creation:

1. Find the pkey index containing the default pkey, and use that index
   if found.  ib_find_pkey() returns the index of the
   limited-membership default pkey (0x7FFF) if the full-member default
   pkey is not in the table.

2. If neither form of the default pkey is found, use pkey index 0
   (previous behavior).
