Allow architectures to create arch/xxx/Makefile.postlink with targets
for vmlinux, modules.ko, and clean, which will be invoked after final
linking of vmlinux and modules.
powerpc will use this to check vmlinux linker relocations for sanity,
and may use it to fix up alternate instruction patch branch addresses.

KBUILD_EXTRA_SYMBOLS makes sense only when building external modules.
Moreover, the modpost sets 'external_module' if the -e option is given.

This change postpones recordmcount processing until after all LLVM IR
has been compiled into object files. In order to exclude the critical
functions in kernel/trace/ftrace.c from inspection, we add a new
code section .text..ftrace, where recordmcount doesn't look, and a
__norecordmcount attribute that allows functions to be moved to this
section.

The section mismatch warning can be easy to miss during the kernel build
process. Allow it to be marked as fatal to be easily caught and prevent
bugs from slipping in.
Setting CONFIG_SECTION_MISMATCH_WARN_ONLY=y causes these warnings to be
non-fatal, since there are a number of section mismatches when using
allmodconfig on some architectures, and we do not want to break these

Commit ea4054a23 (modpost: handle huge numbers of modules) added
support for building a large number of modules.
Unfortunately, the commit changed the semantics of the makefile: Instead of
passing only existing object files to modpost, make now passes all expected
object files. If make was started with option -i, this results in a modpost
error if a single file failed to build.
Example with the current btrfs build falure on m68k:
fs/btrfs/btrfs.o: No such file or directory
make[1]: [__modpost] Error 1 (ignored)
This error is followed by lots of errors such as:
m68k-linux-gcc: error: arch/m68k/emu/nfcon.mod.c: No such file or directory
m68k-linux-gcc: fatal error: no input files
compilation terminated.
make[1]: [arch/m68k/emu/nfcon.mod.o] Error 1 (ignored)
This doesn't matter much for normal builds, but it is annoying for builds
started with "make -i" due to the large number of secondary errors.
Those errors unnececessarily clog any error log and make it difficult
to find the real errors in the build.
Fix the problem by adding a new parameter '-n' to modpost. If this parameter
is specified, modpost reports but ignores missing object files.
With this patch, error output from above problem is (with make -i):
m68k-linux-ld: cannot find fs/btrfs/ioctl.o: No such file or directory
make[2]: [fs/btrfs/btrfs.o] Error 1 (ignored)
...
fs/btrfs/btrfs.o: No such file or directory (ignored)

If CONFIG_MODULE_SIG is set, then this patch will cause all modules files to
to have signatures added. The following steps will occur:
(1) The module will be linked to foo.ko.unsigned instead of foo.ko
(2) The module will be stripped using both "strip -x -g" and "eu-strip" to
ensure minimal size for inclusion in an initramfs.
(3) The signature will be generated on the stripped module.
(4) The signature will be appended to the module, along with some information
about the signature and a magic string that indicates the presence of the
signature.
Step (3) requires private and public keys to be available. By default these
are expected to be found in files:
signing_key.priv
signing_key.x509
in the base directory of the build. The first is the private key in PEM form
and the second is the X.509 certificate in DER form as can be generated from
openssl:
openssl req \
-new -x509 -outform PEM -out signing_key.x509 \
-keyout signing_key.priv -nodes \
-subj "/CN=H2G2/O=Magrathea/CN=Slartibartfast"
If the secret key is not found then signing will be skipped and the unsigned
module from (1) will just be copied to foo.ko.
If signing occurs, lines like the following will be seen:
LD [M] fs/foo/foo.ko.unsigned
STRIP [M] fs/foo/foo.ko.stripped
SIGN [M] fs/foo/foo.ko
will appear in the build log. If the signature step will be skipped and the
following will be seen:
LD [M] fs/foo/foo.ko.unsigned
STRIP [M] fs/foo/foo.ko.stripped
NO SIGN [M] fs/foo/foo.ko
NOTE! After the signature step, the signed module _must_not_ be passed through
strip. The unstripped, unsigned module is still available at the name on the
LD [M] line. This restriction may affect packaging tools (such as rpmbuild)
and initramfs composition tools.

This error may happen when the user's id or path includes .ko string.
For example, user's id is xxx.ko and building test.ko module,
the test.mod file lists ko name and all object files.
/home/xxx.ko/kernel_dev/device/drivers/test.ko
/home/xxx.ko/kernel_dev/device/drivers/test_main.o
/home/xxx.ko/kernel_dev/device/drivers/test_io.o ...
Current Makefile.modpost and Makefile.modinst find and list up not
only test.ko but also other object files.
because all of object file's path includes .ko string.

It is now possible to assign options to AS, CC and LD
on the command line - which is only used when building modules.
{A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile
in the arch makefiles, thus users had no way to specify
additional options to AS, CC, LD when building modules
without overriding the original value.
Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE
that is used by arch specific files and free up
{A,C,LD}FLAGS_MODULE so they can be assigned on
the command line.
All arch Makefiles that used the old variables has been updated.
Note: Previously we had a MODFLAGS variable for both
AS and CC. But in favour of consistency this was dropped.
So in some cases arch Makefile has one assignmnet replaced by
two assignmnets.
Note2: MODFLAGS was not documented and is dropped
without any notice. I do not expect much/any breakage
from this.

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.
I merely merged the patches from Roland, Wenji and Takashi here.

When we introduced support for KBUILD_EXTRA_SYMBOLS
we started to include the externam module's kbuild
file when doing the final modpost step.
As external modules often do:
ccflags-y := -I$(src)
We had problems because $(src) was unassinged and
gcc then used the next parameter for -I resulting in
strange build failures.
Fix is to assign $(src) and $(obj) when building
external modules.

This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous
to the Module.symvers file, the build will now write a Module.markers file
when CONFIG_MARKERS=y is set. This file lists the name, defining module, and
format string of each marker, separated by \t characters. This simple text
file can be used by offline build procedures for instrumentation code,
analogous to how System.map and Module.symvers can be useful to have for
kernels other than the one you are running right now.
The strings are made easy to extract by having the __trace_mark macro define
the name and format together in a single array called __mstrtab_* in the
__markers_strings section. This is straightforward and reliable as long as
the marker structs are always defined by this macro. It is an unreasonable
amount of hairy work to extract the string pointers from the __markers section
structs, which entails handling a relocation type for every machine under the
sun.

Previously we did do the check on the .o files used to link
vmlinux but that failed to find questionable references across
the .o files.
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.
For a defconfig build this is instant but for an allyesconfig this
add two minutes to a full build (that anyways takes ~2 hours).

At stage 2 modpost utility is used to check modules. In case of unresolved

IMHO it is a good idea to fail compilation process in case of unresolved
symbols (at least in modules coming with kernel), since usually such errors
are left unnoticed, but kernel modules are broken.

This fixes one of the worst kbuild warts left - the broken dependencies used
to check and regenerate the .config file. This was done via an indirect
dependency and the .config itself had an empty command, which can cause make
not to reread the changed .config file.
Instead of this we generate now a new file include/config/auto.conf from
.config, which is used for kbuild and has the proper dependencies. It's also
the main make target now for all files generated during this step (and thus
replaces include/linux/autoconf.h).
This also means we can now relax the syntax requirements for the .config file
and we don't have to rewrite it all the time, i.e. silentoldconfig only
writes .config now when it's necessary to keep it in sync with the Kconfig
files and even this can be suppressed by setting the environment variable
KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

The kbuild system takes advantage of an incorrect behavior in GNU make.

even if nothing has changed. This patch ensures kbuild works with both
the incorrect and correct behaviors of GNU make.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
