b13d3720ec topology: Fix sparc64 build.
Due to changeset ba84be2338 ("remove
linux/hardirq.h from asm-generic/local.h") the sparc64 build started
failing on drivers/base/topology.c:

  drivers/base/topology.c: In function ‘show_physical_package_id’:
  drivers/base/topology.c:103: error: implicit declaration of function ‘cpu_data’
  drivers/base/topology.c:103: error: request for member ‘proc_id’ in something not a structure or union
  drivers/base/topology.c: In function ‘show_core_id’:
  drivers/base/topology.c:106: error: request for member ‘core_id’ in something not a structure or union

Adding the obvious fix of including asm/cpudata.h into asm/topology.h on
sparc64 doesn't fix it, in fact it makes things worse because of the
header file dependency chain:

	linux/gfp.h --> linux/mmzone.h --> linux/topology.h -->
	asm/topology.h --> asm/cpudata.h --> linux/percpu.h -->
	linux/slab.h

which results in:

  include/linux/slub_def.h: In function ‘kmalloc_large’:
  include/linux/slub_def.h:209: error: implicit declaration of function ‘__get_free_pages’
  include/linux/slub_def.h:209: error: ‘__GFP_COMP’ undeclared (first use in this function)
  include/linux/slub_def.h:209: error: (Each undeclared identifier is reported only once
  include/linux/slub_def.h:209: error: for each function it appears in.)
  include/linux/slub_def.h:209: warning: cast to pointer from integer of different size

The simplest thing to do is to add yet another one-off hack like parts
of the guilty changeset did, by putting an explicit linux/hardirq.h
include into drivers/base/topology.c

399b835be3 kbuild: add a symlink to the source for separate objdirs
I have some scripts which need to map back to the source directory
from an objdir. This was so far done by parsing the Makefile,
but the Makefile format changes occasionally and breaks my scripts
then.

To make this more reliable add a "source" symlink back.

8e54701ea8 kconfig: add script to manipulate .config files on the command line
I often change single options in .config files. Instead of using
an editor or one of the frontends it's convenient to do this from
the command line. It's also useful to do from automated build scripts
when building different variants from a base config file.

I extracted most of the CONFIG manipulation code from one of my
build scripts into a new shell script scripts/config

The script is not integrated with the normal Kconfig machinery
and doesn't do any checking against Kconfig files, but just manipulates
that text format. This is always done at make time anyways.

I believe this script would be a useful standard addition for scripts/*

Sample usage:

./scripts/config --disable smp
Disable SMP in .config file

./scripts/config --file otherdir/.config --module e1000e
Enable E1000E as module in otherdir/.config

./scripts/config --state smp
y
Check state of config option CONFIG_SMP

After merging into git please make scripts/config executable

4f628248a5 kbuild: reintroduce ALLSOURCE_ARCHS support for tags/cscope
This patch reintroduce the ALLSOURCE_ARCHS support for tags/TAGS/
cscope targets. The Kbuild previously has this feature, but after
moving the targets into scripts/tags.sh, ALLSOURCE_ARCHS disappears.

It's something like this:

	$ make ALLSOURCE_ARCHS="x86 mips arm" tags cscope

40c8c85a47 bootchart: improve output based on Dave Jones' feedback
Dave Jones, in his blog, had some feedback about the bootchart script:
Primarily his complaint was that shorter delays weren't visualized.

The reason for that was that too small delays will have their labels
mixed up in the graph in an unreadable mess.

This patch has a fix for this; for one, it makes the output wider,
so more will fit.
The second part is that smaller delays are now shown with a
much smaller font for the label; while this isn't per se
readable at a 1:1 zoom, at least you can zoom in with most SVG
viewing applications and see what it is you are looking at.

8b249b6856 fix modules_install via NFS
Rafael reported:

I get the following error from 'make modules_install' on my test boxes:

  HOSTCC  firmware/ihex2fw
/home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system
compilation terminated.
make[3]: *** [firmware/ihex2fw] Error 1
make[2]: *** [_modinst_post] Error 2
make[1]: *** [sub-make] Error 2
make: *** [all] Error 2

where the configuration is that the kernel is compiled on a build box
with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by
each test box (full path to this directory is the same on the build box and on
the test boxes).  Then, I cd into <destdir>, run 'make modules_install' and get
the error above.

The issue turns out to be that we when we install firmware pick
up the list of firmware blobs from firmware/Makefile.
And this triggers the Makefile rules to update ihex2fw.

There were two solutions for this issue:
1) Move the list of firmware blobs to a separate file
2) Avoid ihex2fw rebuild by moving it to scripts

As I seriously beleive that the list of firmware blobs should be
done in a fundamental different way solution 2) was selected.

a0e280e0f3 stop_machine/cpu hotplug: fix disable_nonboot_cpus
disable_nonboot_cpus calls _cpu_down. But _cpu_down requires that the
caller already created the stop_machine workqueue (like cpu_down does).
Otherwise a call to stop_machine will lead to accesses to random memory
regions.

When introducing this new interface (9ea09af3bd
"stop_machine: introduce stop_machine_create/destroy") I missed the second
call site of _cpu_down.
So add the missing stop_machine_create/destroy calls to disable_nonboot_cpus
as well.

Fixes suspend-to-ram/disk and also this bug:

514ec71f72 i2400m/SDIO: TX and RX path backends
Implements the backend so that the generic driver can TX/RX to/from
the SDIO device.

For RX, when data is ready the SDIO IRQ is fired and that will
allocate an skb, put all the data there and then pass it to the
generic driver RX code for processing and delivery.

TX, when kicked by the generic driver, will schedule work on a
driver-specific workqueue that pulls data from the TX FIFO and sends
it to the device until it drains it.

Thread contexts are needed as SDIO functions are blocking.

a8ebf98f54 i2400m/USB: TX and RX path backends
Implements the backend so that the generic driver can TX/RX to/from
the USB device.

TX is implemented with a kthread sitting in a never-ending loop that
when kicked by the generic driver's TX code will pull data from the TX
FIFO and send it to the device until it drains it. Then it goes back
sleep, waiting for another kick.

RX is implemented in a similar fashion, but reads are kicked in by the
device notifying in the interrupt endpoint that data is ready. Device
reset notifications are also sent via the notification endpoint.

We need a thread contexts to run USB autopm functions (blocking) and
to process the received data (can get to be heavy in processing
time).

aa5a7acabe i2400m: RX and TX data/control paths
Handling of TX/RX data to/from the i2400m device (IP packets, control
and diagnostics). On RX, this parses the received read transaction
from the device, breaks it in chunks and passes it to the
corresponding subsystems (network and control).

Transmission to the device is done through a software FIFO, as
data/control frames can be coalesced (while the device is reading the
previous tx transaction, others accumulate). A FIFO is used because at
the end it is resource-cheaper that scatter/gather over USB. As well,
most traffic is going to be download (vs upload).

backends for the actual upload). The most critical thing in here is
the piece that puts the device in boot-mode from any other
(undetermined) state, otherwise, it is just pushing the bytes from the

ce6cde9280 i2400m: linkage to the networking stack
Implementation of the glue to the network stack so the WiMAX device
shows up as an Ethernet device.

Initially we shot for implementing a Pure IP device -- however, the
world seems to turn around Ethernet devices. Main issues were with the
ISC DHCP client and servers (as they don't understand types other than
Ethernet and Token Ring).

We proceeded to register with IANA the PureIP hw type, so that DHCP
requests could declare such. We also created patches to the main ISC
DHCP versions to support it. However, until all that permeates into
deployments, there is going to be a long time.

So we moved back to wrap Ethernet frames around the PureIP device. At
the time being this has overhead; we need to reallocate with space for
an Ethernet header. The reason is the device-to-host protocol
coalesces many network packets into a single message, so we can't
introduce Ethernet headers without overwriting valid data from other
packets.

Coming-soon versions of the firmware have this issue solved.

ea24652d25 i2400m: host/device procotol and core driver definitions
The wimax/i2400m.h defines the structures and constants for the
host-device protocols:

 - boot / firmware upload protocol

 - general data transport protocol

 - control protocol

It is done in such a way that can also be used verbatim by user space.

drivers/net/wimax/i2400m.h defines all the APIs used by the core,
bus-generic driver (i2400m) and the bus specific drivers
(i2400m-BUSNAME). It also gives a roadmap to the driver
implementation.

debug-levels.h adds the core driver's debug settings.

3e91029ae0 i2400m: documentation and instructions for usage
The driver for the i2400m is a stacked driver. There is a core driver,
the bus-generic driver that has no knowledge or dependencies on how
the device is connected to the system; it only knows how to speak the
device protocol. Then there are the bus-specific drivers (for USB and
SDIO) that provide backends for the generic driver to communicate with
the device.

The bus generic driver connects to the network and WiMAX stacks on the
top side, and on the bottom to the bus-specific drivers.

3e65646bb1 wimax: basic API: kernel/user messaging, rfkill and reset
Implements the three basic operations provided by the stack's control
interface to WiMAX devices:

- Messaging channel between user space and driver/device

  This implements a direct communication channel between user space
  and the driver/device, by which free form messages can be sent back
  and forth.

  This is intended for device-specific features, vendor quirks, etc.

- RF-kill framework integration

  Provide most of the RF-Kill integration for WiMAX drivers so that
  all device drivers have to do is after wimax_dev_add() is call
  wimax_report_rfkill_{hw,sw}() to update initial state and then every
  time it changes.

  Provides wimax_rfkill() for the kernel to call to set software
  RF-Kill status and/or query current hardware and software switch
  status.

  Exports wimax_rfkill() over generic netlink to user space.

- Reset a WiMAX device

  Provides wimax_reset() for the kernel to reset a wimax device as
  needed and exports it over generic netlink to user space.

This API is clearly limited, as it still provides no way to do the
basic scan, connect and disconnect in a hardware independent way.  The
WiMAX case is more complex than WiFi due to the way networks are
discovered and provisioned.

The next developments are to add the basic operations so they can be
offerent by different drivers. However, we'd like to get more vendors
to jump in and provide feedback of how the user/kernel API/abstraction
layer should be.

The user space code for the i2400m, as of now, uses the messaging
channel, but that will change as the API evolves.

3efb40c2c6 genetlink: export genl_unregister_mc_group()
Add an EXPORT_SYMBOL() to genl_unregister_mc_group(), to allow
unregistering groups on the run. EXPORT_SYMBOL_GPL() is not used as
the rest of the functions exported by this module (eg:
genl_register_mc_group) are also not _GPL().

Cleanup is currently done when unregistering a family, but there is
no way to unregister a single multicast group due to that function not
being exported. Seems to be a mistake as it is documented as for
external consumption.

This is needed by the WiMAX stack to be able to cleanup unused mc
groups.

15530dfd33 wimax: generic device management (registration, deregistration, lookup)
Implements the basic life cycles of a 'struct wimax_dev', some common
generic netlink functionality for marshalling calls to user space,
and the device state machine.

For looking up net devices based on their generic netlink family IDs,
use a low overhead method that optimizes for the case where most
systems have a single WiMAX device, or at most, a very low number of
WiMAX adaptors.

ea912f4e7f wimax: debug macros and debug settings for the WiMAX stack
This file contains a simple debug framework that is used in the stack;
it allows the debug level to be controlled at compile-time (so the
debug code is optimized out) and at run-time (for what wasn't compiled
out).

This is eventually going to be moved to use dynamic_printk(). Just
need to find time to do it.
