An oops dump also contains the register values.

This patch parses these for (32 bit) x86, and then annotates the

Currently, it is no longer possible to use the tags file to jump to
system call function definitions with sys_foo, because the definitions

Josh Hunt fc370ecfdb kbuild: add vmlinux to kernel rpm
We are building an automated system to test kernels weekly and need to
provide an rpm to our QA dept.  We would like to use the ability to create
kernel rpms already in the kernel's Makefile, but need the vmlinux file
included in the rpm for later debugging.

This patch adds a compressed vmlinux to the kernel rpm when doing a
make rpm-pkg or binrpm-pkg and upon install places the vmlinux file in /boot.

Randy Dunlap b4870bc5ee kernel-doc: fix syscall wrapper processing
Fix kernel-doc processing of SYSCALL wrappers.

The SYSCALL wrapper patches played havoc with kernel-doc for
syscalls.  Syscalls that were scanned for DocBook processing
reported warnings like this one, for sys_tgkill:

Warning(kernel/signal.c:2285): No description found for parameter 'tgkill'
Warning(kernel/signal.c:2285): No description found for parameter 'pid_t'
Warning(kernel/signal.c:2285): No description found for parameter 'int'

because the macro parameters all "look like" function parameters,
although they are not:

/**
 *  sys_tgkill - send signal to one specific thread
 *  @tgid: the thread group ID of the thread
 *  @pid: the PID of the thread
 *  @sig: signal to be sent
 *
 *  This syscall also checks the @tgid and returns -ESRCH even if the PID
 *  exists but it's not belonging to the target process anymore. This
 *  method solves the problem of threads exiting and PIDs getting reused.
 */
SYSCALL_DEFINE3(tgkill, pid_t, tgid, pid_t, pid, int, sig)
{
...

This patch special-cases the handling SYSCALL_DEFINE* function
prototypes by expanding them to
	long sys_foobar(type1 arg1, type1 arg2, ...)

Arjan van de Ven d32ad102c6 script: improve markup_oops.pl to also decode oopses in modules
There has been some light flamewar on lkml about decoding oopses
in modules (as part of the crashdump flamewar).

Now this isn't rocket science, just the markup_oops.pl script
cheaped out and didn't handle modules. But really; a flamewar
all about that?? What happened to C++ in the kernel or reading
files from inside the kernel?

This patch adds module support to markup_oops.pl; it's not the
most pretty perl but it works for my testcases...

Andi Kleen 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

Arjan van de Ven 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.

Sam Ravnborg 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.

Wolfram Sang 1e85572697 checkpatch: Add warning for p0-patches
Some people work internally with -p0-patches which has the danger that one
forgets to convert them to -p1 before mainlining.  Bitten myself and seen
p0-patches in mailing lists occasionally, this patch adds a warning to
checkpatch.pl in case a patch is -p0.  If you really want, you can fool
this check to generate false positives, this is why it just spits a
warning.  Making the check 100% proof is trickier than it looks, so let's
start with a version which catches the cases of real use.

Andy Whitcroft 65863862ba checkpatch: dissallow spaces between stars in pointer types
Disallow spaces within multiple pointer stars (*) in both casts and
definitions.  Both of these would now be reported:

	(char * *)
	char * *foo;

Also now consistently detects and reports the attributes within these
structures making the error report itself clearer.

Andy Whitcroft fae17daed7 checkpatch: comment ends inside strings is most likely not an open comment
When we are detecting whether a comment is open when we start a hunk we
check for the first comment edge in the hunk and assume its inverse.
However if the hunk contains something like below, then we will assume
that a comment was open.  Update this heuristic to see if the comment edge
is obviously within double quotes and ignore it if so:

	foo(" */);

Andy Whitcroft 8e761b04a3 checkpatch: detect multiple bitfield declarations
Detect the colons (:) which make up secondary bitfield declarations and
apply binary colon checks.  For example the following is common idiom:

	int foo:1,
	    bar:1;
