Merge branch 'WIP.sched/core' into sched/core 

Conflicts:

Pick up the waitqueue related renames - it didn't get much feedback,
so it appears to be uncontroversial. Famous last words? ;-)

DPAA Ethernet Overview
======================
DPAA stands for Data Path Acceleration Architecture and it is a
set of networking acceleration IPs that are available on several
generations of SoCs, both on PowerPC and ARM64.
The Freescale DPAA architecture consists of a series of hardware blocks
that support Ethernet connectivity. The Ethernet driver depends upon the
following drivers in the Linux kernel:
- Peripheral Access Memory Unit (PAMU) (* needed only for PPC platforms)
drivers/iommu/fsl_*
- Frame Manager (FMan)
drivers/net/ethernet/freescale/fman
- Queue Manager (QMan), Buffer Manager (BMan)
drivers/soc/fsl/qbman
A simplified view of the dpaa_eth interfaces mapped to FMan MACs:
dpaa_eth /eth0\ ... /ethN\
driver | | | |
------------- ---- ----------- ---- -------------
-Ports / Tx Rx \ ... / Tx Rx \
FMan | | | |

--------- -------------- --- -------------- ---------

where the acronyms used above (and in the code) are:
DPAA = Data Path Acceleration Architecture
FMan = DPAA Frame Manager
QMan = DPAA Queue Manager
BMan = DPAA Buffers Manager
QMI = QMan interface in FMan
BMI = BMan interface in FMan
FMan SP = FMan Storage Profiles
MURAM = Multi-user RAM in FMan
FQ = QMan Frame Queue
Rx Dfl FQ = default reception FQ
Rx Err FQ = Rx error frames FQ
Tx Cnf FQ = Tx confirmation FQs
Tx FQs = transmission frame queues
dtsec = datapath three speed Ethernet controller (10/100/1000 Mbps)
tgec = ten gigabit Ethernet controller (10 Gbps)
memac = multirate Ethernet MAC (10/100/1000/10000)
DPAA Ethernet Supported SoCs
============================
The DPAA drivers enable the Ethernet controllers present on the following SoCs:
# PPC
P1023
P2041
P3041
P4080
P5020
P5040
T1023
T1024
T1040
T1042
T2080
T4240
B4860
# ARM
LS1043A
LS1046A
Configuring DPAA Ethernet in your kernel
========================================
To enable the DPAA Ethernet driver, the following Kconfig options are required:
# common for arch/arm64 and arch/powerpc platforms
CONFIG_FSL_DPAA=y
CONFIG_FSL_FMAN=y
CONFIG_FSL_DPAA_ETH=y
CONFIG_FSL_XGMAC_MDIO=y
# for arch/powerpc only
CONFIG_FSL_PAMU=y
# common options needed for the PHYs used on the RDBs
CONFIG_VITESSE_PHY=y
CONFIG_REALTEK_PHY=y
CONFIG_AQUANTIA_PHY=y
DPAA Ethernet Frame Processing
==============================
On Rx, buffers for the incoming frames are retrieved from one of the three
existing buffers pools. The driver initializes and seeds these, each with
buffers of different sizes: 1KB, 2KB and 4KB.
On Tx, all transmitted frames are returned to the driver through Tx
confirmation frame queues. The driver is then responsible for freeing the
buffers. In order to do this properly, a backpointer is added to the buffer
before transmission that points to the skb. When the buffer returns to the
driver on a confirmation FQ, the skb can be correctly consumed.
DPAA Ethernet Features
======================
Currently the DPAA Ethernet driver enables the basic features required for
a Linux Ethernet driver. The support for advanced features will be added
gradually.
The driver has Rx and Tx checksum offloading for UDP and TCP. Currently the Rx
checksum offload feature is enabled by default and cannot be controlled through
ethtool.
The driver has support for multiple prioritized Tx traffic classes. Priorities
range from 0 (lowest) to 3 (highest). These are mapped to HW workqueues with
strict priority levels. Each traffic class contains NR_CPU TX queues. By
default, only one traffic class is enabled and the lowest priority Tx queues
are used. Higher priority traffic classes can be enabled with the mqprio
qdisc. For example, all four traffic classes are enabled on an interface with
the following command. Furthermore, skb priority levels are mapped to traffic
classes as follows:
* priorities 0 to 3 - traffic class 0 (low priority)
* priorities 4 to 7 - traffic class 1 (medium-low priority)
* priorities 8 to 11 - traffic class 2 (medium-high priority)
* priorities 12 to 15 - traffic class 3 (high priority)
tc qdisc add dev <int> root handle 1: \
mqprio num_tc 4 map 0 0 0 0 1 1 1 1 2 2 2 2 3 3 3 3 hw 1
Debugging
=========
The following statistics are exported for each interface through ethtool:
- interrupt count per CPU
- Rx packets count per CPU
- Tx packets count per CPU
- Tx confirmed packets count per CPU
- Tx S/G frames count per CPU
- Tx error count per CPU
- Rx error count per CPU
- Rx error count per type
- congestion related statistics:
- congestion status
- time spent in congestion
- number of time the device entered congestion
- dropped packets count per cause
The driver also exports the following information in sysfs:
- the FQ IDs for each FQ type
/sys/devices/platform/dpaa-ethernet.0/net/<int>/fqids
- the IDs of the buffer pools in use
/sys/devices/platform/dpaa-ethernet.0/net/<int>/bpids

needs to maintain fairness and performance. Please review current
research and RFC's before developing new modules.
The method that is used to determine which congestion control mechanism is
determined by the setting of the sysctl net.ipv4.tcp_congestion_control.
The default congestion control will be the last one registered (LIFO);
so if you built everything as modules, the default will be reno. If you
build with the defaults from Kconfig, then CUBIC will be builtin (not a
module) and it will end up the default.
The default congestion control mechanism is chosen based on the
DEFAULT_TCP_CONG Kconfig parameter. If you really want a particular default
value then you can set it using sysctl net.ipv4.tcp_congestion_control. The
module will be autoloaded if needed and you will get the expected protocol. If
