bc081dd6e9 kbuild: generate modules.builtin
To make it easier for module-init-tools and scripts like mkinitrd to
distinguish builtin and missing modules, install a modules.builtin file
listing all builtin modules. This is done by generating an additional
config file (tristate.conf) with tristate options set to uppercase 'Y'
or 'M'. If we source that config file, the builtin modules appear in
obj-Y.

6299fee7b8 genksyms: properly consider EXPORT_UNUSED_SYMBOL{,_GPL}()
Despite being unused these should also get a CRC calculated.
Primarily I view this as a consistency thing.  But I also think this is
one of the reasons why __crc_* need to be weak (which I think should be
avoided, and hence we should have the goal to eliminate this so that
failure to calculate a proper CRC for a symbol causes the build to fail).

d8379ab1dd unifdef: update to upstream revision 1.190
Fix handling of input files (e.g. with no newline at EOF) that could
make unifdef get into an unexpected state and call abort().

The new -B option compresses blank lines around a deleted section
so that blank lines around "paragraphs" of code don't get doubled.

The evaluator can now handle macros with arguments, and unbracketed
arguments to the "defined" operator.

Add myself to MAINTAINERS for unifdef.

eb8f844c0a kbuild: specify absolute paths for cscope
Cscope doesn't hadle relative paths when cscope.out is not in $PWD. Use
absolute paths when generating cscope.files, which seems to be the
recommended way to generate cscope.out, anyway (at least according to
cscope.sf.net). The speed and size differences are minimal, the only
drawback is that the database needs to be regenerated if the source
directory is moved.

db1d18657c scripts/package: deb-pkg: use fakeroot if available
Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or
becoming root oneself or it errors out.  Unless already running
as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a
good default.

With this patch applied, you can run "make oldconfig deb-pkg" as
an ordinary user to build a binary package for an updated kernel
tree and it should just work.

fakeroot is too zealous by default in treating files as owned by
root.  Its wrapped stat() sets st_uid and st_gid to 0 for all
files, which causes Git to go on a wild goose chase if
CONFIG_LOCALVERSION_AUTO is set, checking if any file's content
has changed along with its stat information.  Avoid this by
telling fakeroot to use the actual owner and group for
preexisting files, by passing it the -u option.

05ba4488a5 scripts/package: add KBUILD_PKG_ROOTCMD variable
Let the deb-pkg target acquire (fake) root privileges before
running commands that need them.  Without such privileges,
deb-pkg errors out because chown fails.

The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a
command to run other commands with possibly fake elevated
privileges.  Since this is not needed for the tar-pkg and rpm-pkg
targets, it is only used by deb-pkg.  If it is not defined, the
behavior is as before, and the user will have to rerun make as
root.

In other words, as a shortcut, instead of running 'make oldconfig &&
make && fakeroot -u make deb-pkg', one can use the single command
'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

91d161857c scripts/package: tar-pkg: use tar --owner=root
Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root.  Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.

Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.

24a675e8b8 kbuild: search arch/$ARCH/include before include/
The namespace used in arch/$ARCH/include is different from
what is used in include/ except for the include/asm directory.

This patch gives the arch/$ARCH/include/asm directory priority
over include/asm.

When we add asm-offsets.h to arch/$ARCH/include/asm/ this
patch makes sure we pick up the arch specific version
and not the one we have in include/asm.

The situation with an asm-offsets.h file located in
both include/asm _and_ arch/$ARCH/include/asm will happen
when we move more files over to include/generated.

This happens because in some cases it is not practical
to rename all users so we simply add a file
in arch/$ARCH/include/asm that includes the generated version.

This is the solution we use for asm-offsets.h as an example.
