UBUNTU: [Upstream] Complete fsl qe/udc driver conversion

Two commits:
 - 79149b8bd0270a268344300a77a2dd3f51039f14
 - ec39e2aeeff2901ef1b1d8ea09533e4b86ad89bb

Did not completely convert the fsl gadget drivers to use the desc in
usb_ep as described in commit messages. Fix the macros that were still
referencing the old pointer.

UBUNTU: [Upstream] PPC: PCI: Fix pcibios_io_space_offset() so it works for 32-bit ptr/64-bit rsrcs

The commit introducing pcibios_io_space_offset() was ignoring 32-bit to
64-bit sign extention, which is the case on ppc32 with 64-bit resource
addresses. This only seems to have shown up while running under QEMU for
e500mc target. It may or may be suboptimal that QEMU has an IO base
address > 32-bits for the e500-pci implementation, but 1) it's still a
regression and 2) it's more correct to handle things this way.

UBUNTU: [Upstream] SCSI: AACRAID: Use resource_size_t for IO mem pointers and offsets

This also stops using the "legacy crap" in Scsi_Host (shost->base is an
unsigned long).

This affected 32-bit systems that have 64-bit resource sizes, causing the
IO address to be truncated.

UBUNTU: [Upstream] SCSI: AACRAID: Better handling of in-flight events on thread stop

When an error occured that would shut down the driver, some in-flight
events were getting caught up, deadlocking a CPU or two.

UBUNTU: [Upstream] SCSI: AACRAID: Relax the tight timeout loop on fib commands

The loop that waited for syncronous fib commands was causing a CPU stall
when a timeout actually occured.

1) Switch to using a more accurate timeout mechanism.
2) Do not pace the loop with udelay(). Use cpu_relax() to allow for
   scheduling to occur.

UBUNTU: [Upstream] SCSI: AACRAID: Fix endian issues in core and SRC portions of driver

This may not fix all endian issues in this driver, but it does get the
driver working on PowerPC for a PMC SRC card. So it should at least fix
all the problems in the core and in the SRC support.

UBUNTU: SAUCE: net: Add support for handling queueing in hardware

The QDisc code does a bunch of locking which is unnecessary if
you have hardware which handles all of the queueing.  Add
support for this, and skip over all of the queueing code if
the feature is enabled on a given device. This code breaks
QDisc support on dpaa_eth, and also coopts the FCOE feature
bit.

UBUNTU: SAUCE: Convert MDIO and PHY Lib drivers to support 10G

10G MDIO is a totally different protocol (clause 45 of 802.3).
Supporting this new protocol requires a couple of changes:

* Add a new parameter to the mdiobus_read functions to specify the
  "device address" inside the PHY.
* Add a phy45_read command which takes advantage of that new parameter
* Add a generic PHY driver for 10G PHYs
* Convert fsl_pq_mdio.c to the new API
