Due to changeset ba84be2338d3a2b6020d39279335bb06fcd332e1 ("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

kconfig: add script to manipulate .config files on the command line
kbuild: reintroduce ALLSOURCE_ARCHS support for tags/cscope

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.

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

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.

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.

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.

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 (9ea09af3bd3090e8349ca2899ca2011bd94cda85
"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:

Check for ACPI resource conflicts in hwmon drivers. I've included
all Super-I/O and PCI drivers.
I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
pretty much mean that they conflict on all systems, and we would know
by now.
* Legacy ISA drivers (lm78 and w83781d): they only support chips found
on old designs were ACPI either wasn't supported or didn't deal with
thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
the checks are already done where they belong, i.e. in the bus drivers.

It turns out that we cannot create a pci_driver in this driver because PCI will
not call this module's probe function if the i5000-edac driver is already
loaded. That said, we only want one value (AMBASE) from the PCI config space.
Neither driver alters this value, so it's safe to read it. However, we still
want the module aliases, so provide that.

More F8000 prep work. Take over the checking if the hwmon part is not
powered down from the standalone f8000 driver.
This check is valid for all supported models.

Simplify fan and temp hyst. handling by treating the registers as an array of
nibbles instead of using switch cases. Also unify the way hysts are handled
between temp and fans, the temp code was storing the actual per temp hyst
values in 4 u8's, where as the fan code was storing actual register values.

While working on adding F8000 support I noticed that various of the
store sysfs functions (and a few of the show also) had issues.
This patch fixes the following issues in these functions:
* store: storing the result of strto[u]l in an int, resulting in a possible
overflow before boundary checking
* store: use of f71882fg_update_device(), we don't want to read the whole
device in store functions, just the registers we need
* store: use of cached register values instead of reading the needed regs
in the store function, including cases where f71882fg_update_device() was
not used, this could cause real isues
* show: shown value is a calculation of 2 or more cached register reads,
without locking the data struct.

This patch is a preparation patch for adding F8000 support to the f71882fg
driver. If you look at the register addresses and esp, the bits used for
the temperature channels, then you will notice that it appears that they
start at 1 in a system meant to start at 0. As the F8000 actually uses the 0
addresses and bits, this patch changes the f71882fg driver to take 4
temperatures numbered 0-3 in to account, using 1-3 in this new scheme for
the temperatures actually present in the F718x2FG.

The f71882fg driver did some io to ioports it hadn't reserved yet in its
find (detect) function, this patches moves this io to the probe function
where these ports are reserved and this io belongs.

This patch adds support for the Fintek f71862fg superio monitoring
functions to the f71882fg driver.
This support has been tested without problems on a Jetway J9F2 by
Tony McConnell.

Add PWM (fan speed control) support to the f71882fg driver. Both
manual control and automatic (temperature-based) modes are supported.
Additionally, each mode has a PWM-based and an RPM-based variant. By
default we use the mode set by the BIOS.
