It is now time for the ipath driver to begin to be phased out of the kernel.
This patch moves the ipath driver from the Infiniband sub tree to the staging
area where it will remain until the code is removed from the kernel in a few
releases.

disabled
We are burrying direct access to MTRR code support on
x86 in order to take advantage of PAT. In the future, we
also want to make the default behaviour of ioremap_nocache()
to use strong UC, use of mtrr_add() on those systems
would make write-combining void.
In order to help both enable us to later make strong
UC default and in order to phase out direct MTRR access
code port the driver over to arch_phys_wc_add() and
annotate that the device driver requires systems to
boot with PAT disabled, with the 'nopat' kernel parameter.
This is a workable compromise given that the ipath device
driver powers the old HTX bus cards that only work in
AMD systems, while the newer IB/qib device driver
powers all PCI-e cards. The ipath device driver is
obsolete, hardware is hard to find and because of this
its a reasonable compromise to require users of ipath
to boot with 'nopat'.

The ib_qib driver is taking over support for QLogic PCIe QLE devices,
so remove support for them from ib_ipath. The ib_ipath driver now
supports only the obsolete QLogic Hyper-Transport IB host channel
adapter (model QHT7140).

Before IBA7220 support was added, the ipath driver didn't support any
hardware unless PCI_MSI and/or HT_IRQ was enabled. However, the
IBA7220 can generate INTx interrupts, so it makes sense to allow the
driver to be build even if PCI_MSI=n and HT_IRQ=n.

The PCI Express and Hypertransport chip-specific source files should only
be built when the kernel has the capability of actually compiling them.
This fixes the driver build on, for example, ia64.

There is little point in keeping the two drivers separate, so we are
merging them.
