84dd4676f5 [POWERPC] Move of_platform_driver initialisations: arch/powerpc
We no longer initialise the name and owner fields of the
of_platform_driver, but use the fields of the embedded device_driver's
name field instead.

b0e81ebb10 [POWERPC] axonram: Do not delete gendisks queue in error path
On exit do not delete gendisk's queue because this is already done by
del_gendisk(). Doing it twice may cause memory damage.

fedcd2c53d [POWERPC] axonram: Module modification for latest firmware API changes
Firmware would not deliver two interrupt numbers in device-tree any more
but only one, for correctable ECC, because uncorrectable ECC from now
is handled by firmware itself.
Changes in the axonram module are necessary because in the old version, if
it is not allowed to fetch the second interrupt number from device-tree,
it interpretes this as an error case and exits.

dbdf04c401 [CELL] driver for DDR2 memory on AXON
The Axon bridge chip used on new Cell/B.E. based blade servers
comes with a DDR2 memory controller that can be used to
attach cheap memory modules, as opposed to the high-speed
XDR memory that is used by the CPU itself.

Since the memory controller does not participate in the
cache coherency protocol, we can not use the memory direcly
for Linux applications, but by providing a block device
it can be used for swap space, temporary file storage and
through the use of the direct_access block device operation
for mapping into user addresses, when it is mounted with
an appropriate file system.
