Merge tag 'staging-3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging tree changes from Greg Kroah-Hartman:
 "Here is the big staging tree pull request for the 3.5-rc1 merge
  window.

  Loads of changes here, and we just narrowly added more lines than we
  added:
   622 files changed, 28356 insertions(+), 26059 deletions(-)

  But, good news is that there is a number of subsystems that moved out
  of the staging tree, to their respective "real" portions of the
  kernel.

  Code that moved out was:
	- iio core code
	- mei driver
	- vme core and bridge drivers

  There was one broken network driver that moved into staging as a step
  before it is removed from the tree (pc300), and there was a few new
  drivers added to the tree:
	- new iio drivers
	- gdm72xx wimax USB driver
	- ipack subsystem and 2 drivers

  All of the movements around have acks from the various subsystem
  maintainers, and all of this has been in the linux-next tree for a
  while.

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"

Fixed up various trivial conflicts, along with a non-trivial one found
in -next and pointed out by Olof Johanssen: a clean - but incorrect -
merge of the arch/arm/boot/dts/at91sam9g20.dtsi file.  Fix up manually
as per Stephen Rothwell.
