Brace expansion might not work properly if _buildshell RPM macro
points to a shell other than bash. Particularly, with _bulidshell
defined to /bin/dash it leads to broken build and source symlinks.

Both Debian and kernel archs are "arm64" but UTS_MACHINE and gcc say
"aarch64". Recognizing just the latter should be enough but let's
accept both in case something regresses again or an user sets
UTS_MACHINE=arm64.
Regressed in cfa88c7: arm64: Set UTS_MACHINE in the Makefile.

When attempting to build a Debian kernel package, the "scripts/gcc-plugins"
directory does not exist in the output tree unless CONFIG_GCC_PLUGINS=y.
To avoid errors when not defined, this wraps the failing "find" in a config

When calling `make deb-pkg` on a system with no codename (for example
Arch Linux), lsb_release sometimes outputs `n/a` as the codename.

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.

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.

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.

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.

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.

Make deb-pkg build both source and binary package like make rpm-pkg does.
For people who only need binary kernel package, there is now bindeb-pkg
target, same target also used to build the .deb files if built from the
source package using dpkg-buildpackage.
Generated source package will build the same kernel .config than what
was available for make deb-pkg. The name of the source package can
be set with KDEB_SOURCENAME enviroment variable.
The source package is useful for GPL compliance, or for feeding to a
automated debian package builder.

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:
rpm --define "_builddir ." --target \
x86_64 -bb ./binkernel.spec
rpm --target: unknown option
scripts/package/Makefile:60: recipe for target 'binrpm-pkg' failed
