09155120cf kbuild: Clean up and speed up the localversion logic
Now that we run scripts/setlocalversion during every build, it makes
sense to move all the localversion logic there. This cleans up the
toplevel Makefile and also makes sure that the script is called only
once in 'make prepare' (previously, it would be called every time due to
a variable expansion in an ifneq statement). No user-visible change is
intended, unless one runs the setlocalversion script directly.

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"'.

db9038c89d kbuild: fix the binrpm-pkg target to work with KBUILD_OUTPUT set
The binrpm-pkg target (binary RPM only) fails when called with
KBUILD_OUTPUT set. This patch makes it work.

For the rpm-pkg target (source + binary RPM), building with
KBUILD_OUTPUT set is not possible and also not needed as the
actual build is done in a temporary directory anyway, so check
that KBUILD_OUTPUT is not set in that case to avoid later errors.

b925dbfe3c kbuild: fix 'make rpm' when CONFIG_LOCALVERSION_AUTO=y and using SCM tree
Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source
tree under SCM.  This is due to KERNELRELEASE being different when the initial make
is run and when make is run from rpmbuild.

mkspec creates kernel.spec using KERNELRELEASE:

<mkspec>
echo "%files"
echo '%defattr (-, root, root)'
echo "%dir /lib/modules"
echo "/lib/modules/$KERNELRELEASE"
echo "/lib/firmware"
echo "/boot/*"
echo ""
</mkspec>

When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any
additional version info from SCM.  Next, the srctree is tarred up and SCM
information is excluded.

rpmbuild reruns make and in the process generates a new include/config/kernel.release
and thus a new KERNELRELEASE.  However this time the SCM information is gone so
KERNELRELEASE no longer has the additional version information.  When "make modules_install"
runs, it uses the new KERNELRELEASE value to determine where to install the modules.
This conflicts with where the spec file assumes they are going because of the
mis-matching KERNELRELEASE versions.

4f1933620f kbuild: change kbuild to not rely on incorrect GNU make behavior
The kbuild system takes advantage of an incorrect behavior in GNU make.
Once this behavior is fixed, all files in the kernel rebuild every time,
even if nothing has changed.  This patch ensures kbuild works with both
the incorrect and correct behaviors of GNU make.

For more details on the incorrect behavior, see:

http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html

Changes in this patch:
  - Keep all targets that are to be marked .PHONY in a variable, PHONY.
  - Add .PHONY: $(PHONY) to mark them properly.
  - Remove any $(PHONY) files from the $? list when determining whether
    targets are up-to-date or not.

6073aa643f kbuild: tar-pkg with out-out-tree building
Fix out-of-tree builds for the tar-pkg targets

When I wrote the buildtar script, I didn't even think about
out-of-tree builds because I didn't use these back then. This patch
throughoutly uses ${objtree} instead of `pwd`.

Also, the kernel version is no longer manually built. Instead, it will
properly use $KERNELRELEASE .  Installing modules is only done if
CONFIG_MODULES is set.

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!
