dd951fc1b6 scripts: add Linux .cocciconfig for coccinelle
Coccinelle supports reading .cocciconfig, the order of precedence for
variables for .cocciconfig is as follows:

 o Your current user's home directory is processed first
 o Your directory from which spatch is called is processed next
 o The directory provided with the --dir option is processed last, if used

Since coccicheck runs through make, it naturally runs from the kernel
proper dir, as such the second rule above would be implied for picking up a
.cocciconfig when using 'make coccicheck'.

'make coccicheck' also supports using M= targets.If you do not supply
any M= target, it is assumed you want to target the entire kernel.
The kernel coccicheck script has:

    if [ "$KBUILD_EXTMOD" = "" ] ; then
        OPTIONS="--dir $srctree $COCCIINCLUDE"
    else
        OPTIONS="--dir $KBUILD_EXTMOD $COCCIINCLUDE"
    fi

KBUILD_EXTMOD is set when an explicit target with M= is used. For both cases
the spatch --dir argument is used, as such third rule applies when
whether M= is used or not, and when M= is used the target directory can
have its own .cocciconfig file. When M= is not passed as an argument to
coccicheck the target directory is the same as the directory from where
spatch was called.

If not using the kernel's coccicheck target, keep the above precedence order
logic of .cocciconfig reading. If using the kernel's coccicheck target,
override any of the kernel's .coccicheck's settings using SPFLAGS.

We help Coccinelle when used against Linux with a set of sensible defaults
options for Linux with our own Linux .cocciconfig. This hints to coccinelle
git can be used for 'git grep' queries over coccigrep. A timeout of 200
seconds should suffice for now.

The options picked up by coccinelle when reading a .cocciconfig do not appear
as arguments to spatch processes running on your system, to confirm what
options will be used by Coccinelle run:

  spatch --print-options-only

You can override with your own preferred index option by using SPFLAGS.
Coccinelle supports both glimpse and idutils. Glimpse had historically
provided the best performance, however recent benchmarks reveal idutils
is performing just as well. Due to some recent fixes however you however
will need at least coccinelle >= 1.0.6 if using idutils.

Coccinelle carries a script scripts/idutils_index.sh which creates the
idutils database with as follows:

    mkid -i C --output .id-utils.index

If using just "--use-idutils" coccinelle expects your idutils database to be
on the top level of the kernel as a file named ".id-utils.index". If you do
not use this you can symlink your database file to it, or you can specify the
database file following the "--use-idutils" argument. Examples:

    make SPFLAGS=--use-idutils coccicheck

This assumes you have $srctree/.id-utils.index, where $srctree is
the top level of the kernel.

    make SPFLAGS="--use-idutils /full-path/to/ID" coccicheck

Here you specify the full path of the idutils ID database. Using
.cocciconfig is possible, however given the order of precedence followed
by Coccinelle, and since the kernel now carries its own .cocciconfig,
you will need to use SPFLAGS to use idutils if desired.

v4:

o Recommend upgrade for using idutils with coccinelle due to some
  recent fixes.

o Refer to using --print-options-only for testing what options are
  picked up by .cocciconfig reading.

o Expand commit log considerably explaining *why* .cocconfig from
  two precedence rules are used when using coccicheck, and how to
  properly override these if needed.

o Expand Documentation/coccinelle.txt

v3: Expand commit log a bit more

6b90bd4ba4 GCC plugin infrastructure
This patch allows to build the whole kernel with GCC plugins. It was ported from
grsecurity/PaX. The infrastructure supports building out-of-tree modules and
building in a separate directory. Cross-compilation is supported too.
Currently the x86, arm, arm64 and uml architectures enable plugins.

The directory of the gcc plugins is scripts/gcc-plugins. You can use a file or a directory
there. The plugins compile with these options:
 * -fno-rtti: gcc is compiled with this option so the plugins must use it too
 * -fno-exceptions: this is inherited from gcc too
 * -fasynchronous-unwind-tables: this is inherited from gcc too
 * -ggdb: it is useful for debugging a plugin (better backtrace on internal
    errors)
 * -Wno-narrowing: to suppress warnings from gcc headers (ipa-utils.h)
 * -Wno-unused-variable: to suppress warnings from gcc headers (gcc_version
    variable, plugin-version.h)

The infrastructure introduces a new Makefile target called gcc-plugins. It
supports all gcc versions from 4.5 to 6.0. The scripts/gcc-plugin.sh script
chooses the proper host compiler (gcc-4.7 can be built by either gcc or g++).
This script also checks the availability of the included headers in
scripts/gcc-plugins/gcc-common.h.

The gcc-common.h header contains frequently included headers for GCC plugins
and it has a compatibility layer for the supported gcc versions.

The gcc-generate-*-pass.h headers automatically generate the registration
structures for GIMPLE, SIMPLE_IPA, IPA and RTL passes.

Note that 'make clean' keeps the *.so files (only the distclean or mrproper
targets clean all) because they are needed for out-of-tree modules.

Based on work created by the PaX Team.

fb11794991 modsign: Use single PEM file for autogenerated key
The current rule for generating signing_key.priv and signing_key.x509 is
a classic example of a bad rule which has a tendency to break parallel
make. When invoked to create *either* target, it generates the other
target as a side-effect that make didn't predict.

So let's switch to using a single file signing_key.pem which contains
both key and certificate. That matches what we do in the case of an
external key specified by CONFIG_MODULE_SIG_KEY anyway, so it's also
slightly cleaner.

866ced950b kbuild: Support split debug info v4
This is an alternative approach to lower the overhead of debug info
(as we discussed a few days ago)

gcc 4.7+ and newer binutils have a new "split debug info" debug info
model where the debug info is only written once into central ".dwo" files.

This avoids having to copy it around multiple times, from the object
files to the final executable. It lowers the disk space
requirements. In addition it defaults to compressed debug data.

More details here: http://gcc.gnu.org/wiki/DebugFission

This patch adds a new option to enable it. It has to be an option,
because it'll undoubtedly break everyone's debuginfo packaging scheme.
gdb/objdump/etc. all still work, if you have new enough versions.

I don't see big compile wins (maybe a second or two faster or so), but the
object dirs with debuginfo get significantly smaller. My standard kernel
config (slightly bigger than defconfig) shrinks from 2.9G disk space
to 1.1G objdir (with non reduced debuginfo). I presume if you are IO limited
the compile time difference will be larger.

Only problem I've seen so far is that it doesn't play well with older
versions of ccache (apparently fixed, see
https://bugzilla.samba.org/show_bug.cgi?id=10005)

v2: various fixes from Dirk Gouders. Improve commit message slightly.
v3: Fix clean rules and improve Kconfig slightly
v4: Fix merge error in last version (Sam Ravnborg)
    Clarify description that it mainly helps disk size.

da01ee3c8e .gitignore: remove stale entry for generated version.h
Since userspace headers were moved to generated/uapi it possible to have a
stale copy of linux/version.h at that file's old location.  This causes
confusion after building an older kernel version, then checking out and
building a new one; the old (stale) version header will still get picked
up until it is manually removed.  This upsets the C library.

Since the uapi changes, include/linux/version.h is no longer generated and
should not be ignored, so this patch removes it from .gitignore.

d8ecc5cd8e kbuild: asm-generic support
There is an increasing amount of header files
shared between individual architectures in asm-generic.
To avoid a lot of dummy wrapper files that just
include the corresponding file in asm-generic provide
some basic support in kbuild for this.

With the following patch an architecture can maintain
a list of files in the file arch/$(ARCH)/include/asm/Kbuild

To use a generic file just add:

        generic-y += <name-of-header-file.h>

For each file listed kbuild will generate the necessary
wrapper in arch/$(ARCH)/include/generated/asm.

When installing userspace headers a wrapper is likewise created.

The original inspiration for this came from the unicore32
patchset - although a different method is used.

The patch includes several improvements from Arnd Bergmann.
Michael Marek contributed Makefile.asm-generic.

Remis Baima did an intial implementation along to achive
the same - see https://patchwork.kernel.org/patch/13352/

f7f16b7799 kbuild: drop include/asm
We no longer use this directory for generated files and
all architectures has moved their header files so no
symlink tricks are needed either.

Drop the symlink and drop the ARCH check.

If we really need to check that the SRCARCH has not changed
when we build a kernel we can add this check back - but then we will
find a more convenient way to store the info.

559df2e021 kbuild: move asm-offsets.h to include/generated
The simplest method was to add an extra asm-offsets.h
file in arch/$ARCH/include/asm that references the generated file.

We can now migrate the architectures one-by-one to reference
the generated file direct - and when done we can delete the
temporary arch/$ARCH/include/asm/asm-offsets.h file.

f14875a3e0 kbuild: support include/generated
We need a location for generated files.
Today they are spread over several places and bringing them
together to a common place makes it obvious hat is generated
and what isreal files.

Al Viro originally suggested: include/gen
Linus suggested to spell it out.

This patch implement support for

    include/generated

All files in include/generated are ignored by git.
include/generated is removed during "make mrproper".

With this we are ready to implement support for include/generated
in the various architctures and in the base kernel.

f72e9df0e0 Fix and clean top .gitignore
Removed vmlinux* rule because it matches too many useful files, replacing
it with rules matching filetype by filename (e.g. *.gz). Also unignored
.mailmap from the top directory. Added a comment telling the user how to
check for tracked files being ignored.

    # Untracked files:
    #   (use "git add <file>..." to include in what will be committed)
    #
    #       ncscope.out
    nothing added to commit but untracked files present (use "git add"
to track)

Fix it.

1f5d3a6b65 Remove *.rej pattern from .gitignore
With commit 3f1b0e1f28 ".gitignore update"
Linus's current git tree starts to ignore any "*.rej" files.
So "git status" no longer shows these files, but the ones who works with
quilt patchsets, this not makes life easier as expected.
Because sometimes a work flow (at least for me) requires
"quilt push -f" followed by "git status" to see unresolved merge
conflicts, work on these conflicts to correct them and finalize
the patch with "quilt refresh".

And if there are some "*.rej" files exists in tree, for whatever
reason, this means something goes really wrong there and i think
this situation not deserves to be ignored.
