      kbuild: add a symlink to the source for separate objdirs · 399b835b
      Andi Kleen authored 
      
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.

      kconfig: add script to manipulate .config files on the command line · 8e54701e
      Andi Kleen authored 
      
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

      kbuild: reintroduce ALLSOURCE_ARCHS support for tags/cscope · 4f628248
      Jike Song authored 
      
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

      bootchart: improve output based on Dave Jones' feedback · 40c8c85a
      Arjan van de Ven authored 
      
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.

      fix modules_install via NFS · 8b249b68
      Sam Ravnborg authored 
      
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.

Satisfy these requirements for the linux/qnx*.h headers.

      Fix up 64-bit byte swaps for most 32-bit architectures · ede6f5ae
      Linus Torvalds authored 
      
The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the
no-longer-existant ___swab32() method (three underscores).  We got rid
of some of the worst indirection and complexity, and now it should just
use the 32-bit swab function that was defined right above it.
