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 Signed-off-by: NEmil Medve <Emilian.Medve@Freescale.com> Change-Id: I3acb223893e42003d6c9dc061db568ec0b10d29b Signed-off-by: NScott Wood <scottwood@freescale.com>

8xx sometimes need to load a invalid/non-present TLBs in it DTLB asm handler. These must be invalidated separaly as linux mm doesn't. Commit 5efab4a0 was invalidating them in arch/powerpc/mm/fault.c. 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 fault.c Signed-off-by: NChristophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: NScott Wood <scottwood@freescale.com>

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" * tag 'for-linus-20141102' of git://git.infradead.org/linux-mtd: mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chips mtd: omap: fix mtd devices not showing up mtd: m25p80,spi-nor: Fix module aliases for m25p80 mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id mtd: m25p80: get rid of spi_get_device_id

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.
