b41d920acf kbuild: deb-pkg: split generating packaging and build
Move debian/ directory generation out of builddeb to a new script,
mkdebian. The package build commands are kept in builddeb, which
is now an internal command called from debian/rules.

With these changes in place, we can now use dpkg-buildpackage from
deb-pkg and bindeb-pkg removing need for handrolled source/changes
generation.

This patch is based on the criticism of the current state of builddeb
discussed on:

8a6105c481 kbuild: rpm-pkg: Support GNU tar >= 1.29
There is a change in how command line parsing is done in this version.
Excludes and includes are now ordered with the file list. Since
the spec file puts the file list before the exclude list it means newer
tar ignores the excludes and packs all the build output into the
kernel-devel RPM resulting in a huge package.

Simple argument re-ordering fixes the problem.

262dad68e1 kbuild: pkg: make out-of-tree rpm/deb-pkg build immediately fail
We do not support out-of-tree building of rpm-pkg / deb-pkg.  If O=
is given, the build should be terminated, but the "false" command is
not effective since it is not the last command in the cmd_src_tar.
Then, rpm-pkg / deb-pkg tries to continue building, and fails for a
different reason.

Set -e option so that the "false" terminates the building immediately.

I also put the error messages to stderr, and made it stand out more.

For example, "make O=foo rpm-pkg" will fail as follows:

  /bin/bash ../scripts/package/mkspec >./kernel.spec
    TAR     kernel-4.15.0_rc2+.tar.gz

    ERROR:
    Building source tarball is not possible outside the
    kernel source tree. Don't set KBUILD_OUTPUT, or use the
    binrpm-pkg or bindeb-pkg target instead.

5704d4557f scripts/package: snap-pkg target
Following in footsteps of other targets like 'deb-pkg, 'rpm-pkg' and 'tar-pkg',
this patch adds a 'snap-pkg' target for the creation of a Linux kernel snap
package using the kbuild infrastructure.

A snap, in its general form, is a self contained, sandboxed, universal package
and it is intended to work across multiple distributions and/or devices. A snap
package is distributed as a single compressed squashfs filesystem.

A kernel snap is a snap package carrying the Linux kernel, kernel modules,
accessory files (DTBs, System.map, etc) and a manifesto file.  The purpose of a
kernel snap is to carry the Linux kernel during the creation of a system image,
eg. Ubuntu Core, and its subsequent upgrades.

For more information on snap packages: https://snapcraft.io/docs/

ebaad7d364 kbuild: rpm: prompt to use "rpm-pkg" if "rpm" target is used
The "rpm" has been kept for backward compatibility since pre-git era.
I am planning to remove it after the Linux 4.18 release.  Annouce the
end of the support, prompting to use "rpm-pkg" instead.

If you use "rpm", it will work like "rpm-pkg", but warning messages
will be displayed as follows:

2dbc644ac6 kbuild: pkg: use --transform option to prefix paths in tar
For rpm-pkg and deb-pkg, a source tar file is created.  All paths in
the archive must be prefixed with the base name of the tar so that
everything is contained in the directory when you extract it.

Currently, scripts/package/Makefile uses a symlink for that, and
removes it after the tar is created.

If you terminate the build during the tar creation, the symlink is
left over.  Then, at the next package build, you will see a warning
like follows:

  ln: '.' and 'kernel-4.14.0+/.' are the same file

It is possible to fix it by adding -n (--no-dereference) option to
the "ln" command, but a cleaner way is to use --transform option
of "tar" command.  This option is GNU extension, but it should not
hurt to use it in the Linux build system.

The 'S' flag is needed to exclude symlinks from the path fixup.
Without it, symlinks in the kernel are broken.

bace64800b builddeb: Pass the kernel:debarch substvar to dpkg-genchanges
At the end of "make bindeb-pkg" I noticed the following warning:

dpkg-genchanges: warning: unknown substitution variable ${kernel:debarch}

It turns out that since dpkg version 1.19.0 dpkg-genchanges honors
substitution variables in the Description field, while earlier
versions silently left them alone, see https://bugs.debian.org/856547.

The result is an incomplete description of the linux-headers package
in the generated .changes file.  Fix it by passing the kernel:debarch
substitution variable to dpkg-genchanges.

8a16a070ab kbuild: rpm-pkg: do not force -jN in submake
The spec file always passes %{?_smp_mflags}, but we have two
problems here.

[1] "make -jN rpm-pkg" emits the following warning message:

    make[2]: warning: -jN forced in submake: disabling jobserver mode.

[2] We can not specify the number of jobs that run in parallel.
    Whether we give -jN or not from the top Makefile, the spec file
    always passes ${?_smp_mflags} to the build commands.

${?_smp_mflags} will be useful when we run rpmbuild by hand.  When we
invoke it from Makefile, -jN is propagated down to submake; it should
not be overridden because we want to respect the number of jobs given
by the user.  Set _smp_mflags to empty string in this case.

The repeat of echo is unreadable.  The here-document is a well-known
device for such scripts.  One difficulty is we have a bunch of PREBUILT

My idea is to add "$S" annotatation to lines only for the source package

easier than repeat of "cat <<EOF ..."

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

25b080bd53 kbuild: rpm-pkg: fix version number handling
The "Release:" field of the spec file is determined based on the
.version file.

However, the .version file is not copied to the source tar file.
So, when we build the kernel from the source package, the UTS_VERSION
always indicates #1.  This does not match with "rpm -q".

The kernel UTS_VERSION and "rpm -q" do not agree for binrpm-pkg, either.
Please note the kernel has already been built before the spec file is
created.  Currently, mkspec invokes mkversion.  This script returns an
incremented version.  So, the "Release:" field of the spec file is
greater than the version in the kernel by one.

For the source package build (where .version file is missing), we can
give KBUILD_BUILD_VERSION=%{release} to the build command.

For the binary package build, we can simply read out the .version file
because it contains the version number that was used for building the
kernel image.

We can remove scripts/mkversion because scripts/package/Makefile need
not touch the .version file.

ca617dc68b builddeb: fix file permissions before packaging
Builddep is not very explicit about file permissions. Actually the file
permissions in the package are largely influenced by the umask of the
user cloning the git and building the package. If that umask does not
set go+r the resulting linux-headers package will prevent non-root users
from building out-of-tree modules. And that is probably just one
unexpected effect.
Being a packaging/install tool builddep should make sure the file
permissions are set correctly and not just derived from a value that is
never checked.

This patch sets ugo read permissions for all packaged files and derives
the executable bit for directories and executables from the file-owner.

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.

c8b08ca558 kbuild/mkspec: fix grub2 installkernel issue
mkspec is copying built kernel to temporrary location

	/boot/vmlinuz-$KERNELRELEASE-rpm

and runs installkernel on it. This however directly leads to grub2
menuentry for this suffixed binary being generated as well during the run
of installkernel script.

Later in the process the temporary -rpm suffixed files are removed, and
therefore we end up with spurious (and non-functional) grub2 menu entries
for each installed kernel RPM.

Fix that by using a different temporary name (prefixed by '.'), so that
the binary is not recognized as an actual kernel binary and no menuentry
is created for it.

4b63f60313 package Makefile: fix perf-tar targets when outdir is set
building with $srctree != $objtree, perf-tar-* targets fail
to read the MANIFEST file and add the PERF-VERSION-FILE needed
by out-of-tree builds. The build errors and an incorrect tar is created:

$ make O=build-x86 perf-targz-src-pkg
  TAR
cat: ../tools/perf/MANIFEST: No such file or directory
tar: perf-4.1.0-rc8/PERF-VERSION-FILE: Cannot stat: No such file or
dir..
tar: Exiting with failure status due to previous errors

Kbuild sets objtree to "." and srctree to ".." The command to output
MANIFEST becomes:

   $(cd ..; echo $(cat ../tools/perf/MANIFEST))

Without MANIFEST, the entire kernel source tree is added to the perf
source tarball. The *correct* fix is to keep the cd and remove srctree
from cat command line since MANIFEST has wildcards that fail to expand
working directory isn't srctree.

Second, PERF-VERSION-FILE gets not added, because in-tree build path is
hardcoded to Makefile:

   util/PERF-VERSION-GEN ../../$(perf-tar)/ 2>/dev/null)

The PERF-VERSION-GEN needs to be run from tools/perf directory,
and the output directory needs to be changed from relative to
to absolute. This can be achieved using the $(CURDIR) variable.

Also remove the error redirect to /dev/null which hid the error.

63a478fbc0 deb-pkg: Add automatic support for armhf architecture
The Debian armhf architecture uses the ARM EABI hard-float variant,
whereas armel uses the soft-float variant.  Although the kernel
doesn't use FP itself, CONFIG_VFP must be enabled to support
hard-float userland and will probably be disabled when supporting a
soft-float userland.  So set the architecture to armhf by default when
CONFIG_AEABI and CONFIG_VFP are both enabled.

Commit 3716001bcb ("deb-pkg: add source package") added the ability to
create a debian changelog file.  This exposed that previously the
builddeb script hasn't cleared debian/files between builds.

As debian/files keeps accumulating entries, the changes file will end up
growing indefinelty.  With outdated entries in debian/files, builddeb
script will exit with failure.  This regression impacts those who use
"make deb-pkg" target to build kernel into a .deb package and never use
"make mrproper" or other means to clean kernel tree from generated
directories.

To fix the regression, remove debian/files before starting build and in
the generated clean rule.

21a59991ce scripts/package/Makefile: rpmbuild is needed for rpm targets
Before rpm release 4.1, in 2002, either the rpm command or the
rpmbuild command could be used in the rpm-pkg or binrpm-pkg targets,
and the Makefile chose the rpm command if the rpmbuild command wasn't
found.

After release 4.1, however, the rpm command could no longer be used in
place of the rpmbuild command.  As the rpmbuild command is not
installed by default, this can lead to failures with the rpm-pkg and
binrpm-pkg targets:

ca2a9d2cf6 deb-pkg: Add device tree blobs to the package
When building a package with make deb-pkg (say, for arm), the dtb files are
not added to the package. Given that things are still evolving on arm, it
make sense to have them along with the kernel and modules.

64178cb62c builddeb: fix stripped module signatures if CONFIG_DEBUG_INFO and CONFIG_MODULE_SIG_ALL are set
If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are
automatically signed in the result package, as it's for rpm-pkg, binrpm-pkg,
tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO
is NOT set. In that case deb-package contains signed modules.

But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with
debug information. To do that, debug information from all modules
is copied into separate files by objcopy. And loadable kernel modules are
stripped afterwards. Stripping removes previously (during modules_install)
added signatures from loadable kernel modules. Therefore final deb-package
contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL.

This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set
to solve this problem.

d9f711db83 builddeb: Try to determine distribution
lsb_release command is a good choice to determine the distribution
name for the changelog file in the generated Debian packages [1].
Its installation is no precondition.
In Debian it is still not essential or build-essential.

Ben gave some helpful informations and detailed explanations in [2].
There he also suggested to have an option to explicitly set the
distribution name (see $KDEB_CHANGELOG_DIST variable).

Embedded the improvement as suggested by Thorsten (see [3]):

"This is suboptimal: if KDEB_CHANGELOG_DIST is defined,
lsb_release is not necessary. The following snippet
also omits using its output if it fails but still
produces any:"

Dealing with this issue I learned about "The Colon in the Shell." and
possible pitfalls in this area (see [4,5]). Furthermore, refreshed my
knowledge about redirecting outputs with the echo command (see [5]).
Special thanks to Thorsten, I enjoyed the IRC session with you.

Cooked together the snippets of Ben and Thorsten (see [2,3]).
Tested against Linux v3.19-rc2.

Thanks goes to Alexander, Ben, maximilian and Thorsten for the very
vital help.

sense to assign a 64-bit kernel package to s390x.

7848ea7902 kbuild: Add MIPS specific files to generated package.
A lot of 64-bit systems supported by Linux/MIPS have boot firmware or
bootloaders that only understand 32-bit ELF files, and as such, the vmlinux.32
target exists to support these systems.  Therefore, it'd be nice if the tar-pkg
target recognised this, and included the right version when packaging up a
binary of the kernel.

This updates buildtar to support MIPS targets.  MIPS may use 'vmlinux'
or 'vmlinux.32' depending on the target system.  This uses 'vmlinux.32'
in preference to 'vmlinux' where present (although I should check which
is newer), including either file as /boot/vmlinux-${version}.

in /lib/firmware with a potential conflict with already
installed kernels.

firmware files are now installed in /lib/firmware/<release>
and packaged with the rest of the modules.

c398ff00f5 kbuild: fix error when building from src rpm
The following issue can be reproduced with Linus' tree on
an x86_64 server.

>+ cp /home/user/rpmbuild-test/BUILDROOT/kernel-3.9.2.x86_64/boot/vmlinuz-3.9.2
>cp: missing destination file operand after
>/home/user/rpmbuild-test/BUILDROOT/kernel-3.9.2-1.x86_64/boot/vmlinuz-3.9.2'
>Try `cp --help' for more information.
>error: Bad exit status from /var/tmp/rpm-tmp.R4o0iI (%install)

Here are the commands to reproduce:

make defconfig
make rpm-pkg

Use the resulting src rpm to build as follows:

mkdir ~/rpmbuild-test
cd ~/rpmbuild-test
rpmbuild --rebuild --define "_topdir `pwd`" -vv ~/rpmbuild/SRPMS/kernel-3.10.0_rc1+-1.src.rpm

The issue is because the %install script uses $KBUILD_IMAGE and it hasn't
been set since it is only available in the kbuild system and not in the
%install script.

This patch adds a Makefile target to emit the image_name that can be used
and modifies the mkspec to use the dynamic name in %install.

6615d6c322 rpm-pkg: Do not package the whole source directory
The source tree can contain lots of uninteresting data like tag or
cscope files, packaging which slows down make rpm needlessly. It can
also break the build, if the tree contains an unrelated file named
*.spec. The downside of this change is that new subdirectories have to
be added to the KBUILD_ALLDIRS variable in the top-level Makefile. The
upside is that the behavior is more predictable.

When dealing with multiple sub-arches (like 32- and 64-bit on x86, for
example) generating a bunch of kernel tar archives with the same name
but for different sub-arches could get confusing and error-prone. Also,
the build process could overwrite otherwise unrelated builds and you
probably don't want that. So, add the architecture to the archive name

e0367a6156 kbuild: clear KBUILD_SRC when calling 'make' in RPM spec
'make rpm-pkg' and 'make binrpm-pkg' fail when the kernel source is
read-only.  Specifically, when the RPM spec generated by
scripts/package/mkspec is run, KBUILD_SRC happens to be set to the
source location and thus the invocation of 'make headers_install'
fails when an internal call to 'filechk' tries to write a file into
the source tree.

The fix is to clear KBUILD_SRC for the 'make headers_install'
invocation in the spec file, as is already done for the 'make
modules_install' invocation.

b589c8ae09 Kbuild: use normal compression settings for tar*-pkg
For large kernel configurations (like a distribution kernel)
targz-pkg takes a quite long time to just do the compression.
I clocked it at 15+mins for a SUSE kernel like config on a fast
system.  And tarxz and bzip2 are even slower.

The main reason is that the script that is doing the taring sets
the highest compression level (-9).  When I change it to just
use the defaults the gzip time for the same kernel goes down
to ~3 mins. I haven't tested xz and bzip, but I expect those
to be much faster too.

I'm not willing to wait that long for a small compression
gain. So just change the script to use the defaults.

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.

880df92fa0 scripts: use %_tmppath in "make rpm-pkg"
The mkspec script hardcodes "/var/tmp" into the generated rpm spec file's
BuildRoot. The user, however, may have a custom setting for %_tmppath,
which should be used in BuildRoot.  This patch changes mkspec's
BuildRoot output to appropriately use %_tmppath.

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"'.
