This patch _really_ needs an ack from Greg before I can merge it.

DRIVER CORE, KOBJECTS, DEBUGFS, KERNFS AND SYSFS
M:      Greg Kroah-Hartman <gregkh@linuxfoundation.org>
T:      git git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.gitS:      Supported
F:      Documentation/kobject.txt
F:      drivers/base/

alternatively, the whole series should be taken by Greg, with my ack
for the amba and ARM bits.

Given that Greg is unlikely to respond this close to the merge window
(he's not responded to my messages about the amba-pl011 driver having
been messed up by the wrong patch set being taken...) I think this has
basically missed the 4.5 merge window.  Sorry.
