3794f3e812 docsrc: build Documentation/ sources
Currently source files in the Documentation/ sub-dir can easily bit-rot
since they are not generally buildable, either because they are hidden in
text files or because there are no Makefile rules for them.  This needs to
be fixed so that the source files remain usable and good examples of code
instead of bad examples.

Add the ability to build source files that are in the Documentation/ dir.
Add to Kconfig as "BUILD_DOCSRC" config symbol.

Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the
Documentation/ sources.  Or enable BUILD_DOCSRC in the *config system.
However, this symbol depends on HEADERS_CHECK since the header files need
to be installed (for userspace builds).

Built (using cross-tools) for x86-64, i386, alpha, ia64, sparc32,
sparc64, powerpc, sh, m68k, & mips.

64a99d2a8c kbuild: a better way to generate cscope database change
It's a problem about cscope target of kernel Makefile, and the cscope
plugin of emacs:
1. `make cscope` will generate cscope.files cscope.{in,po,}.out;
2. the cscope plugin expect a cscope.out.{in,po,};
3. the default `cscope -b` would generate cscope.{in,po,}.out;

There are three approach to solve it:
1. modify the cscope C code;
2. modify the cscope emacs plugin lisp code;
3. modify the Makefile;

I have tried to communicate with the cscope upstream, but later I
realize the third approach is most meaningful.

7a48bdd01b kbuild: fix O=.. build with arm
With a make O=... build kbuild would only create
the include2/asm symlink for archs that not yet
had moved headers to include/$ARCH/include

There is no longer any reason to avoid the symlink
for archs that has moved their headers so create it
unconditionally.

This fixes arm because kbuild checked for include/asm-$ARCH/errno.h
and that file was not present for arm but the platform files
are not yet moved.

ea35455e0d kbuild: fix O=... build of um
We used include/asm-$ARCH/system.h to check if
we should create a symlink in include2 directory with
make O=... builds.
But um does not have such a file thus build filed.

a439fe51a1 sparc, sparc64: use arch/sparc/include
The majority of this patch was created by the following script:

***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***

The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.

5e4786f75d kbuild: add arch/$ARCH/include to search path
This patch conclude the support for

   arch/$ARCH/include

Note: The individual architectures will most likely require
      a few minor patches to support locating header files in
      arch/$ARCH/include

Testing shows that it worked out-of-the-box for sparc.
x86 required a few trivial changes in the arch
specific Makefile and a few include paths had to be adjusted.

88181ec30f kbuild: only one call for include/ in make headers_*
Move it to the top-level file to decide if we install/check
the generic headers or the arch specific headers.

This revealed a long standing bug where "make headers_check_all"
relied on the files in asm/ for the current architecture.
So make headers_check_all is now broken by this commit.

In addition:

o add a simpler way to detect if an arch support
  exporting header files.

o add 'set -e;' so we error out early if
  make headers_check_all fails.

o add sparc64 and cris to arch we do not process
  in make headers_*_all because:

    sparc64 - use sparc to export headers
    cris    - is know seriously broken

d35cb360c2 markers: fix duplicate modpost entry
When a kernel was rebuilt, the previous Module.markers was not cleared.
It caused markers with different format strings to appear as duplicates
when a markers was changed.  This problem is present since
scripts/mod/modpost.c started to generate Module.markers, commit
b2e3e658b3

It therefore applies to 2.6.25, 2.6.26 and linux-next.

bef5b54bd7 Fix MIPS cross-compile problem
Crosscompiling on a Fedora 9 machine running gcc 4.3.0 as its host compiler
and gcc 3.4.6 for the mips-linux target results in the following build
error:

$ make malta_defconfig
$ make
cc1: error: unrecognized command line option "-fno-stack-protector"
scripts/kconfig/conf -s arch/mips/Kconfig
cc1: error: unrecognized command line option "-fno-stack-protector"

The arch Makefile is included too late so the host compiler is feature
tested, not the crosscompiler as intended and thus the Makefile applies
adds -fno-stack-protector to crosscompiler's flags which fails for gcc
3.4.6.  The bug was introduced by e06b8b98da
in 2.6.25; 35bb5b1e0e did add more flags
testing before the arch Makefile inclusion.

16444a8a40 ftrace: add basic support for gcc profiler instrumentation
If CONFIG_FTRACE is selected and /proc/sys/kernel/ftrace_enabled is
set to a non-zero value the ftrace routine will be called everytime
we enter a kernel function that is not marked with the "notrace"
attribute.

The ftrace routine will then call a registered function if a function
happens to be registered.

[ This code has been highly hacked by Steven Rostedt and Ingo Molnar,
  so don't blame Arnaldo for all of this ;-) ]

Update:
  It is now possible to register more than one ftrace function.
  If only one ftrace function is registered, that will be the
  function that ftrace calls directly. If more than one function
  is registered, then ftrace will call a function that will loop
  through the functions to call.

5dffbe811b kbuild: show defconfig subdirs in make help
PowerPC will start moving board defconfigs into subarch-specific
subdirs soon.  "make help" currently does not look in subdirs to
find the defconfigs to show.  This is partially a good thing,
since there are way too many defconfigs for one list.

This patch makes the main "make help" display something like

  help-40x         - Show 40x-specific targets
  help-44x         - Show 44x-specific targets
  help-boards      - Show all of the above

and wires up stuff so those new help-* commands actually work.

35bb5b1e0e Add option to enable -Wframe-larger-than= on gcc 4.4
Add option to enable -Wframe-larger-than= on gcc 4.4

gcc mainline (upcoming 4.4) added a new -Wframe-larger-than=...
option to warn at build time about too large stack frames. Add a config
option to enable this warning, since this very useful for the kernel.

I choose (somewhat arbitarily) 2048 as default warning threshold for 64bit
and 1024 as default for 32bit architectures.  With some research and
fixing all the code for smaller values these defaults should be probably
lowered.

With the default allyesconfigs have some new warnings, but I think
that is all code that should be just fixed.

At some point (when gcc 4.4 is released and widely used) this should
obsolete make checkstack

4ce6efed48 kbuild: soften modpost checks when doing cross builds
The module alias support in the kernel have a consistency
check where it is checked that the size of a structure
in the kernel and on the build host are the same.
For cross builds this check does not make sense so detect
when we do cross builds and silently skip the check in these
situations.
This fixes a build bug for a wireless driver when cross building
for arm.

Building vmlinux.o were moved up in the dependency chain so we started
to build it before the kallsym stuff. This was done to let modpost
report section mismatch bugs even when the final link failed.

Originally I had expected the dependency of $(kallsyms.o) to
cover this but it turns out that we need to be even more explicit.
Fix this by adding a conditional dependency on firat target
used in the kallsyms serie of builds.

Some analysis later.. it turns out that the following line

With this line removed the exploit will be nicely stopped.

CFLAGS          += $(call cc-option, -fno-stack-protector)

Now I realize that certain distros have patched gcc to
compensate for their lack of distro wide CFLAGS, and it's
great to work around that... but would there be a way to NOT
disable this for CONFIG_CC_STACKPROTECTOR please?
It would have made this exploit not possible for those kernels
that enable this feature (and that includes distros like Fedora)

Move the assignment to KBUILD_CFLAGS up before including
the arch specific Makefile so arch makefiles may override
the setting.

551559e13a kbuild: implement modules.order
When multiple built-in modules (especially drivers) provide the same
capability, they're prioritized by link order specified by the order
listed in Makefile.  This implicit ordering is lost for loadable
modules.

When driver modules are loaded by udev, what comes first in
modules.alias file is selected.  However, the order in this file is
indeterministic (depends on filesystem listing order of installed
modules).  This causes confusion.

The solution is two-parted.  This patch updates kbuild such that it
generates and installs modules.order which contains the name of
modules ordered according to Makefile.  The second part is update to
depmod such that it generates output files according to this file.

Note that both obj-y and obj-m subdirs can contain modules and
ordering information between those two are lost from beginning.
Currently obj-y subdirs are put before obj-m subdirs.

Sam Ravnborg cleaned up Makefile modifications and suggested using awk
to remove duplicate lines from modules.order instead of using separate
C program.

Jan Altenberg <jan.altenberg@linutronix.de> reported that
building with redirected input like this failed:
make O=dir oldconfig bzImage < /dev/null

The problem were caused by a make silentoldconfig being
run before oldconfig and with a non-recent .config the build
failed because silentoldconfig requires non-redirected stdin.

Silentoldconfig was run as a side-effect of having the
top-level Makefile re-made by make.
Introducing an empty rule for the top-level Makefile
(and Kbuild.include) fixed the issue.

80ef88d6d2 x86: simplify "make ARCH=x86" and fix kconfig all.config
Simplify "make ARCH=x86" and fix kconfig so we again
can set 64BIT in all.config.

For a fix the diffstat is nice:
 6 files changed, 3 insertions(+), 36 deletions(-)

The patch reverts these commits:
0f855aa64b
-> kconfig: add helper to set config symbol from environment variable

2a113281f5
-> kconfig: use $K64BIT to set 64BIT with all*config targets

Roman Zippel pointed out that kconfig supported string
compares so the additional complexity introduced by the
above two patches were not needed.

With this patch we have following behaviour:

# make {allno,allyes,allmod,rand}config [ARCH=...]
option \ host arch      | 32bit         | 64bit
=====================================================
./.                     | 32bit         | 64bit
ARCH=x86                | 32bit         | 32bit
ARCH=i386               | 32bit         | 32bit
ARCH=x86_64             | 64bit         | 64bit

The general rule are that ARCH= and native architecture
takes precedence over the configuration.
So make ARCH=i386 [whatever] will always build a 32-bit
kernel no matter what the configuration says.
The configuration will be updated to 32-bit if it was
configured to 64-bit and the other way around.

This behaviour is consistent with previous behaviour so
no suprises here.

make ARCH=x86 will per default result in a 32-bit kernel
but as the only ARCH= value x86 allow the user to select
between 32-bit and 64-bit using menuconfig.

50a8ec31c3 kbuild: disable depmod in cross-compile kernel build
When building embedded systems in a cross-compile environment and
populating a target's file system image, we don't want to run the
depmod on the host as we may be building for a completely different
architecture. Since there's no such thing as a cross-depmod, we
just disable running depmod in the cross-compile case and we just
run depmod on the target at bootup.

Inspired by patches from Christian, Armin and Deepak.

This solves: http://bugzilla.kernel.org/show_bug.cgi?id=3881

fc333b2df3 kbuild: check asm symlink when building a kernel
We often hit the situation where the asm symlink
in include/ points to the wrong architecture.
In 9 out of 10 cases thats because we forgot to set
ARCH but sometimes we just reused the same tree
for another ARCH. For the merged x86 tree we need
to create a new symlink but this is not obvious.
So with the following patch we check if the symlink
points to the correct architecture and error
out if this is not the case.

0b35786d77 kbuild: call make once for all targets when O=.. is used
Change the invocations of make in the output directory Makefile and the
main Makefile for separate object trees to pass all goals to one $(MAKE)
via a new phony target "sub-make" and the existing target _all.

When compiling with separate object directories, a separate make is called
in the context of another directory (from the output directory the main
Makefile is called, the Makefile is then restarted with current directory
set to the object tree).  Before this patch, when multiple make command
goals are specified, each target results in a separate make invocation.
With make -j, these invocations may run in parallel, resulting in multiple
commands running in the same directory clobbering each others results.

I did not try to address make -j for mixed dot-config and no-dot-config
targets.  Because the order does matter, a solution was not obvious.
Perhaps a simple check for MAKEFLAGS having -j and refusing to run would
be appropriate.

The assembler for a while now supports -gdwarf to generate source line info
just like the C compiler does.  Source-level assembly debugging sounds like an
oxymoron, but it is handy to be able to see the right source file and read its
comments rather than just the disassembly.  This patch enables -gdwarf for
assembly files when CONFIG_DEBUG_INFO=y and the assembler supports the option.

(Oops - should have been O=/ws/linux/obj-2.6.23!)

18991197b4 Use --build-id ld option
This change passes the --build-id when linking the kernel and when linking
modules, if ld supports it.  This is a new GNU ld option that synthesizes an
ELF note section inside the read-only data.  The note in this section contains
unique identifying bits called the "build ID", which are generated so as to be
different for any two linked ELF files that aren't identical.  The build ID
can be recovered from stripped files, memory dumps, etc.  and used to look up
the original program built, locate debuginfo or other details or history
associated with it.  For normal program linking, the compiler passes
--build-id to ld by default, but the option is needed when using ld directly
as we do.

Create a dedicated vmlinux.o file used only for section mismatch checks
that uses the defualt linker script so section does not get renamed.

The vmlinux.o may later be used as part of the the final link of vmlinux
but for now it is used fo section mismatch only.

b46522394d Revert "[PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+"
This reverts commit c8fdd24725.

It turns out the kernel was correct, and the gcc complaint was a gcc
bug.  The preferred stack boundary is expressed not in bytes, but in the
the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2"
is in fact exactly what we want, but a gcc that is compiled for x86-64
will consider it an error (because the 64-bit calling sequence says that
the stack should be 16-byte aligned) even if we are then using "-m32" to
generate 32-bit code.
