2f0a8df40f [I2C] i2c-mv64xxx: Don't set i2c_adapter.retries
I2C adapter drivers are supposed to handle retries on nack by themselves
if they do, so there's no point in setting .retries if they don't.

As this retry mechanism is going away (at least in its current form),
clean this up now so that we don't get build failures later.

a0832798c0 [I2C] Split mv643xx I2C platform support
The motivation for this change is to allow other chips, like the
Marvell Orion ARM SoC family, to use the existing i2c-mv64xxx driver.

b11e9e020c [ARM] Orion: provide GPIO method for enabling hardware assisted blinking
This is a pre-requisite for implementing proper hardware accelerated
GPIO LED flashing, and since we want proper locking, it's sensible to provide
the orion specific orion_gpio_set_blink() implementation within
mach-orion/gpio.c. The functions orion_gpio_set_blink() and gpio_set_value()
implicitly turn off each others state.

585cf17561 [ARM] basic support for the Marvell Orion SoC family
The Marvell Orion is a family of ARM SoCs with a DDR/DDR2 memory
controller, 10/100/1000 ethernet MAC, and USB 2.0 interfaces,
and, depending on the specific model, PCI-E interface, PCI-X
interface, SATA controllers, crypto unit, SPI interface, SDIO
interface, device bus, NAND controller, DMA engine and/or XOR
engine.

This contains the basic structure and architecture register definitions.

e50d64097b [ARM] Marvell Feroceon CPU core support
The Feroceon is a family of independent ARMv5TE compliant CPU core
implementations, supporting a variable depth pipeline and out-of-order
execution.  The Feroceon is configurable with VFP support, and the
later models in the series are superscalar with up to two instructions
per clock cycle.

This patch adds the initial low-level cache/TLB handling for this core.

a9e527e3f9 IPoIB: improve IPv4/IPv6 to IB mcast mapping functions
An IPoIB subnet on an IB fabric that spans multiple IB subnets can't
use link-local scope in multicast GIDs.  The existing routines that
map IP/IPv6 multicast addresses into IB link-level addresses hard-code
the scope to link-local, and they also leave the partition key field
uninitialised.  This patch adds a parameter (the link-level broadcast
address) to the mapping routines, allowing them to initialise both the
scope and the P_Key appropriately, and fixes up the call sites.

The next step will be to add a way to configure the scope for an IPoIB
interface.

88314e4dda RDMA/cma: add support for rdma_migrate_id()
This is based on user feedback from Doug Ledford at RedHat:

Events that occur on an rdma_cm_id are reported to userspace through an
event channel.  Connection request events are reported on the event
channel associated with the listen.  When the connection is accepted, a
new rdma_cm_id is created and automatically uses the listen event
channel.  This is suboptimal where the user only wants listen events on
that channel.

Additionally, it may be desirable to have events related to connection
establishment use a different event channel than those related to
already established connections.

Allow the user to migrate an rdma_cm_id between event channels. All
pending events associated with the rdma_cm_id are moved to the new event
channel.

7299a39184 ide: remove hwif->intrproc
Given that:

* hpt366.c::hpt3xx_intrproc() is the only user of hwif->intrproc

* hpt366.c::hpt3xx_quirkproc() sets drive->quirk_list to 1 for quirky drives
  which is a value unique to hpt366 host driver

we can remove hwif->intproc and just check for drive->quirk_list == 1
in ide_do_request().

  REQ_ATA_TYPE_{CMD,TASK} requests and move it to ide_tf_load()
  so it also covers REQ_ATA_TYPE_TASKFILE requests.
