Merge branch 'for-rmk/hugepages' of git://git.linaro.org/people/stevecapper/linux into devel-stable 

These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM.  Only long descriptors (LPAE) are supported
in this series.

The code has been tested on an Arndale board (Exynos 5250).

Simple Framebuffer
A simple frame-buffer describes a raw memory region that may be rendered to,
with the assumption that the display hardware has already been set up to scan
out from that buffer.
Required properties:
- compatible: "simple-framebuffer"
- reg: Should contain the location and size of the framebuffer memory.
- width: The width of the framebuffer in pixels.
- height: The height of the framebuffer in pixels.
- stride: The number of bytes in each line of the framebuffer.
- format: The format of the framebuffer surface. Valid values are:
- r5g6b5 (16-bit pixels, d[15:11]=r, d[10:5]=g, d[4:0]=b).
Example:
framebuffer {
compatible = "simple-framebuffer";
reg = <0x1d385000 (1600 * 1200 * 2)>;
width = <1600>;
height = <1200>;
stride = <(1600 * 2)>;

In order to initialize the RapidIO subsystem, a platform must initialize and
register at least one master port within the RapidIO network. To register mport
within the subsystem controller driver initialization code calls function
rio_register_mport() for each available master port. After all active master
ports are registered with a RapidIO subsystem, the rio_init_mports() routine
is called to perform enumeration and discovery.
rio_register_mport() for each available master port.
In the current PowerPC-based implementation a subsys_initcall() is specified to
perform controller initialization and mport registration. At the end it directly
calls rio_init_mports() to execute RapidIO enumeration and discovery.
RapidIO subsystem uses subsys_initcall() or device_initcall() to perform
controller initialization (depending on controller device type).
After all active master ports are registered with a RapidIO subsystem,
an enumeration and/or discovery routine may be called automatically or
by user-space command.
4. Enumeration and Discovery
----------------------------
When rio_init_mports() is called it scans a list of registered master ports and
calls an enumeration or discovery routine depending on the configured role of a
master port: host or agent.
4.1 Overview
------------
RapidIO subsystem configuration options allow users to specify enumeration and
discovery methods as statically linked components or loadable modules.
An enumeration/discovery method implementation and available input parameters
define how any given method can be attached to available RapidIO mports:
simply to all available mports OR individually to the specified mport device.
Depending on selected enumeration/discovery build configuration, there are
several methods to initiate an enumeration and/or discovery process:
(a) Statically linked enumeration and discovery process can be started
automatically during kernel initialization time using corresponding module
parameters. This was the original method used since introduction of RapidIO
subsystem. Now this method relies on enumerator module parameter which is
'rio-scan.scan' for existing basic enumeration/discovery method.
When automatic start of enumeration/discovery is used a user has to ensure
that all discovering endpoints are started before the enumerating endpoint
and are waiting for enumeration to be completed.
Configuration option CONFIG_RAPIDIO_DISC_TIMEOUT defines time that discovering
endpoint waits for enumeration to be completed. If the specified timeout
expires the discovery process is terminated without obtaining RapidIO network
information. NOTE: a timed out discovery process may be restarted later using
a user-space command as it is described later if the given endpoint was
enumerated successfully.
(b) Statically linked enumeration and discovery process can be started by
a command from user space. This initiation method provides more flexibility
for a system startup compared to the option (a) above. After all participating
endpoints have been successfully booted, an enumeration process shall be
started first by issuing a user-space command, after an enumeration is
completed a discovery process can be started on all remaining endpoints.
(c) Modular enumeration and discovery process can be started by a command from
user space. After an enumeration/discovery module is loaded, a network scan
process can be started by issuing a user-space command.
Similar to the option (b) above, an enumerator has to be started first.
(d) Modular enumeration and discovery process can be started by a module
initialization routine. In this case an enumerating module shall be loaded
first.
When a network scan process is started it calls an enumeration or discovery
routine depending on the configured role of a master port: host or agent.
Enumeration is performed by a master port if it is configured as a host port by
assigning a host device ID greater than or equal to zero. A host device ID is

The enumeration and discovery routines use RapidIO maintenance transactions
to access the configuration space of devices.
The enumeration process is implemented according to the enumeration algorithm
outlined in the RapidIO Interconnect Specification: Annex I [1].
4.2 Automatic Start of Enumeration and Discovery
------------------------------------------------
Automatic enumeration/discovery start method is applicable only to built-in
enumeration/discovery RapidIO configuration selection. To enable automatic
enumeration/discovery start by existing basic enumerator method set use boot
command line parameter "rio-scan.scan=1".
This configuration requires synchronized start of all RapidIO endpoints that
form a network which will be enumerated/discovered. Discovering endpoints have
to be started before an enumeration starts to ensure that all RapidIO
controllers have been initialized and are ready to be discovered. Configuration
parameter CONFIG_RAPIDIO_DISC_TIMEOUT defines time (in seconds) which
a discovering endpoint will wait for enumeration to be completed.
When automatic enumeration/discovery start is selected, basic method's
initialization routine calls rio_init_mports() to perform enumeration or
discovery for all known mport devices.
Depending on RapidIO network size and configuration this automatic
enumeration/discovery start method may be difficult to use due to the
requirement for synchronized start of all endpoints.
4.3 User-space Start of Enumeration and Discovery
-------------------------------------------------
User-space start of enumeration and discovery can be used with built-in and
modular build configurations. For user-space controlled start RapidIO subsystem
creates the sysfs write-only attribute file '/sys/bus/rapidio/scan'. To initiate
an enumeration or discovery process on specific mport device, a user needs to
write mport_ID (not RapidIO destination ID) into that file. The mport_ID is a
sequential number (0 ... RIO_MAX_MPORTS) assigned during mport device
registration. For example for machine with single RapidIO controller, mport_ID
for that controller always will be 0.
To initiate RapidIO enumeration/discovery on all available mports a user may
write '-1' (or RIO_MPORT_ANY) into the scan attribute file.
4.4 Basic Enumeration Method
----------------------------
This is an original enumeration/discovery method which is available since
first release of RapidIO subsystem code. The enumeration process is
implemented according to the enumeration algorithm outlined in the RapidIO
Interconnect Specification: Annex I [1].
This method can be configured as statically linked or loadable module.
The method's single parameter "scan" allows to trigger the enumeration/discovery
process from module initialization routine.
This enumeration/discovery method can be started only once and does not support
unloading if it is built as a module.
The enumeration process traverses the network using a recursive depth-first
algorithm. When a new device is found, the enumerator takes ownership of that

an agent skips RapidIO discovery and continues with remaining kernel
initialization.
4.5 Adding New Enumeration/Discovery Method
-------------------------------------------
RapidIO subsystem code organization allows addition of new enumeration/discovery
methods as new configuration options without significant impact to to the core
RapidIO code.
A new enumeration/discovery method has to be attached to one or more mport
devices before an enumeration/discovery process can be started. Normally,
method's module initialization routine calls rio_register_scan() to attach
an enumerator to a specified mport device (or devices). The basic enumerator
implementation demonstrates this process.
