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

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:

f29d3b2323 fastboot: Make libata initialization even more async
As suggested by Linus: Don't do the libata init in 2 separate
steps with a global sync inbetween, but do it as one async step,
with a local sync before registering the device.

This cuts the boottime on my machine with 2 sata controllers down
significantly, and it seems to work. Would be nice if the libata
folks take a good look at this patch though..

793180570f fastboot: make the libata port scan asynchronous
This patch makes the libata port scanning asynchronous (per device).
There is a synchronization point before doing the actual disk scan
so that device ordering is not affected.

4ace92fc11 fastboot: make scsi probes asynchronous
This patch makes part of the scsi probe (which is mostly device spin up and the
partition scan) asynchronous. Only the part that runs after getting the device
number allocated is asynchronous, ensuring that device numbering remains stable.

22a9d64567 async: Asynchronous function calls to speed up kernel boot
Right now, most of the kernel boot is strictly synchronous, such that
various hardware delays are done sequentially.

In order to make the kernel boot faster, this patch introduces
infrastructure to allow doing some of the initialization steps
asynchronously, which will hide significant portions of the hardware delays
in practice.

In order to not change device order and other similar observables, this
patch does NOT do full parallel initialization.

Rather, it operates more in the way an out of order CPU does; the work may
be done out of order and asynchronous, but the observable effects
(instruction retiring for the CPU) are still done in the original sequence.

b9acb64a38 hwmon: Check for ACPI resource conflicts
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.

6e31eb2b29 hwmon: (i5k_amb) Load automatically on all 5000/5400 chipsets
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.
