080ba92965 checkpatch: try to catch missing VMLINUX_SYMBOL() in vmlinux.lds.h
Seems like every other release we have someone who updates vmlinux.lds.h
and adds C-visible symbols without VMLINUX_SYMBOL() around them.  So start
checking the file and reject assignments which have plain symbols on
either side.

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.

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(" */);

5aea50b5c7 scripts: script from kerneloops.org to pretty print oops dumps
We're struggling all the time to figure out where the code came from that
oopsed..  The script below (a adaption from a script used by
kerneloops.org) can help developers quite a bit, at least for non-module
cases.

It works and looks like this:

[/home/arjan/linux]$ dmesg | perl scripts/markup_oops.pl vmlinux
 {
 	struct agp_memory *memory;

 	memory = agp_allocate_memory(agp_bridge, pg_count, type);
 c055c10f:	89 c2                	mov    %eax,%edx
 	if (memory == NULL)
 c055c111:	74 19                	je     c055c12c <agp_allocate_memory_wrap+0x30>
 /* This function must only be called when current_controller != NULL */
 static void agp_insert_into_pool(struct agp_memory * temp)
 {
 	struct agp_memory *prev;

 	prev = agp_fe.current_controller->pool;
 c055c113:	a1 ec dc 8f c0       	mov    0xc08fdcec,%eax
*c055c118:	8b 40 10             	mov    0x10(%eax),%eax     <----- faulting instruction

 	if (prev != NULL) {
 c055c11b:	85 c0                	test   %eax,%eax
 c055c11d:	74 05                	je     c055c124 <agp_allocate_memory_wrap+0x28>
 		prev->prev = temp;
 c055c11f:	89 50 04             	mov    %edx,0x4(%eax)
 		temp->next = prev;
 c055c122:	89 02                	mov    %eax,(%edx)
 	}
 	agp_fe.current_controller->pool = temp;
 c055c124:	a1 ec dc 8f c0       	mov    0xc08fdcec,%eax
 c055c129:	89 50 10             	mov    %edx,0x10(%eax)
 	if (memory == NULL)
 		return NULL;

 	agp_insert_into_pool(memory);

so in this case, we faulted while dereferencing agp_fe.current_controller
pointer, and we get to see exactly which function and line it affects...
Personally I find this very useful, and I can see value for having this
script in the kernel for more-than-just-me to use.

Caveats:
* It only works for oopses not-in-modules
* It only works nicely for kernels compiled with CONFIG_DEBUG_INFO
* It's not very fast.
* It only works on x86

b67ff8ce12 kbuild: ignore a few files in headers_check
The new check for asm/types.h and linux/types.h had
a few false positives.

o We cannot let linux/types.h include linux/types.h
o The int-ll64.h and int-ll64.h define the types
  and are included by linux/types.h

Handle this by hardcoding the filenames in the headers_check script.

9bb482476c allow stripping of generated symbols under CONFIG_KALLSYMS_ALL
Building upon parts of the module stripping patch, this patch
introduces similar stripping for vmlinux when CONFIG_KALLSYMS_ALL=y.
Using CONFIG_KALLSYMS_STRIP_GENERATED reduces the overhead of
CONFIG_KALLSYMS_ALL from 245k/310k to 65k/80k for the (i386/x86-64)
kernels I tested with.

The patch also does away with the need to special case the kallsyms-
internal symbols by making them available even in the first linking
stage.

While it is a generated file, the patch includes the changes to
scripts/genksyms/keywords.c_shipped, as I'm unsure what the procedure
here is.

ad7a953c52 kbuild: strip generated symbols from *.ko
This patch changes the way __crc_ symbols are being resolved from
using ld to do so to using the assembler, thus allowing these symbols
to be marked local (the linker creates then as global ones) and hence
allow stripping (for modules) or ignoring (for vmlinux) them. While at
this, also strip other generated symbols during module installation.

One potentially debatable point is the handling of the flags passeed
to gcc when translating the intermediate assembly file into an object:
passing $(c_flags) unchanged doesn't work as gcc passes --gdwarf2 to
gas whenever is sees any -g* option, even for -g0, and despite the
fact that the compiler would have already produced all necessary debug
info in the C->assembly translation phase. I took the approach of just
filtering out all -g* options, but an alternative to such negative
filtering might be to have a positive filter which might, in the ideal
case allow just all the -Wa,* options to pass through.

5dae9a550a genksyms: allow to ignore symbol checksum changes
This adds an "override" keyword for use in *.symvers / *.symref files.
When a symbol is overridden, the symbol's old definition will be used for
computing checksums instead of the new one, preserving the previous
checksum.  (Genksyms will still warn about the change.)

This is meant to allow distributions to hide minor actual as well as fake
ABI changes.  (For example, when extra type information becomes available
because additional headers are included, this may change checksums even
though none of the types used have actully changed.)

This approach also allows to get rid of "#ifdef __GENKSYMS__" hacks in the
code, which are currently used in some vendor kernels to work around
checksum changes.

64e6c1e123 genksyms: track symbol checksum changes
Sometimes it is preferable to avoid changes of exported symbol checksums
(to avoid breaking externally provided modules).  When a checksum change
occurs, it can be hard to figure out what caused this change: underlying
types may have changed, or additional type information may simply have
become available at the point where a symbol is exported.

Add a new --reference option to genksyms which allows it to report why
checksums change, based on the type information dumps it creates with the
--dump-types flag.  Genksyms will read in such a dump from a previous run,
and report which symbols have changed (and why).

The behavior can be controlled for an entire build as follows: If
KBUILD_SYMTYPES is set, genksyms uses --dump-types to produce *.symtypes
dump files.  If any *.symref files exist, those will be used as the
reference to check against.  If KBUILD_PRESERVE is set, checksum changes
will fail the build.

a680eedc6c tags and cscope support really belongs in a shell script
as they do not benefit from the make functionality.

Moving the support to a shell script has several benefits:
- The readability of the code has increased a lot
- More people is able to extend the tags support
- We see less changes to the top-level Makefile

The shell script version includes improvements from:
Alexey Dobriyan <adobriyan@gmail.com> (jump to kconfig symbols)
Alexey Dobriyan <adobriyan@gmail.com> (drop ./ in paths)
Ian Campbell <ijc@hellion.org.uk> (simplified find algorithms)

This version has a few caveats:
=> It does not support ALLSOURCE_ARCHS
   - it is easy to add if it is really used
=> It assumes all archs have moved to arch/$ARCH/include
   - until that happens we have a few additional hits in the archs

efddd79512 remove bashisms from scripts/extract-ikconfig
unbashify-extract-ikconfig.patch

scripts/extract-ikconfig contains a lot of gratuituous bashisms,
which make it fail if /bin/sh isn't bash. This patch replaces them
with regular Bourne shell constructs.

Convert a few echos in the build system to new $(kecho) so we get correct
output according to build verbosity.

5410ecc0de kbuild: introduce $(kecho) convenience echo
There is a bunch of places in the build system where we do 'echo' to show
some nice status lines.  This means we still get output when running in
silent mode.  So declare a new KECHO variable that only does 'echo' when we
are in a suitable verbose build mode.
