Add support for mapping and unmapping of inbound rapidio windows.  This
allows for drivers to open up a part of local memory on the rapidio
network.  Also applications can use this and tranfer blocks of data
over the network.

The clock name "fmanclk" was given in the example, but not specified
in the binding itself.  Made clock-names mandatory as otherwise there's
not much point having it.

Added a reference to the fsl,qman and fsl,bman properties proposed
in http://patchwork.ozlabs.org/patch/407034/ and

The Frame Manager (FMan) combines the Ethernet network interfaces with
packet distribution logic to provide intelligent distribution and
queuing decisions for incoming traffic at line rate.

This binding document describes Freescale's Frame Manager hardware
attributes that are used by the Frame Manager driver for its basic
initialization and configuration.

The Queue Manager is part of the Data-Path Acceleration Architecture
(DPAA).  QMan supports queuing and QoS scheduling of frames to CPUs,
network interfaces and DPAA logic modules, maintains packet ordering
within flows.  Besides providing flow-level queuing, is also
responsible for congestion management functions such as RED/WRED,
congestion notifications and tail discards.  This binding covers the
CCSR space programming model

8xx sometimes need to load a invalid/non-present TLBs in

These must be invalidated separaly as linux mm doesn't.

Commit 5efab4a0 was invalidating them in

This patch does the invalidation earlier in order to free the TLB as soon as
possible. This also has the advantage of removing some 8xx specific code from

Pull MTD fixes from Brian Norris:
 "Three main MTD fixes for 3.18:

   - A regression from 3.16 which was noticed in 3.17.  With the
     restructuring of the m25p80.c driver and the SPI NOR library
     framework, we omitted proper listing of the SPI device IDs.  This
     means m25p80.c wouldn't auto-load (modprobe) properly when built as
     a module.  For now, we duplicate the device IDs into both modules.

   - The OMAP / ELM modules were depending on an implicit link ordering.
     Use deferred probing so that the new link order (in 3.18-rc) can
     still allow for successful probing.

   - Fix suspend/resume support for LH28F640BF NOR flash"

The sk_prot is irda's own set of protocol handlers, so irda should
statically know what that function is anyway, without using an indirect
pointer.  And as it happens, we know *exactly* what that pointer is
statically: it's NULL, because irda doesn't define a disconnect
operation.

So calling that function is doubly wrong, and will just cause an oops.
