kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables

2020-06-11T11:14:41+00:00

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp.
GZIP, BZIP2, LZOP env variables are reserved by the tools. The original
attempt to redefine them internally doesn't work in makefiles/scripts
intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in
broken builds. There can be other broken build commands because of this,
so the universal solution is to use non-reserved env variables for the
compression tools.

kbuild: add variables for compression tools

2020-06-06T14:42:01+00:00

Allow user to use alternative implementations of compression tools,
such as pigz, pbzip2, pxz. For example, multi-threaded tools to
speed up the build:
$ make GZIP=pigz BZIP2=pbzip2

Variables _GZIP, _BZIP2, _LZOP are used internally because original env
vars are reserved by the tools. The use of GZIP in gzip tool is obsolete
since 2015. However, alternative implementations (e.g., pigz) still rely
on it. BZIP2, BZIP, LZOP vars are not obsolescent.

The credit goes to @grsecurity.

As a sidenote, for multi-threaded lzma, xz compression one can use:
$ export XZ_OPT="--threads=0"

kbuild: deb-pkg: fix warning when CONFIG_DEBUG_INFO is unset

2020-03-30T00:23:00+00:00

Creating a Debian package without CONFIG_DEBUG_INFO produces
a warning that no debug package was created.

This patch excludes the debug package from the control file,
if no debug package is created by this configuration.

builddeb: avoid invoking sub-shells where possible

2020-01-28T16:51:30+00:00

The commands surrounded by ( ... ) is run in a sub-shell, but you do
not have to spawn a sub-shell for every single line.

Use just one ( ... ) for creating debian/hdrsrcfiles.

For tar, use -C option instead.

it is already relying on $objtree is '.'

builddeb: match temporary directory name to the package name

2020-01-28T16:51:30+00:00

The temporary directory names, debian/hdrtmp (linux-headers package)
vs debian/headertmp (linux-libc-dev package), are confusing.

Matching the directory name to the package name is clearer, IMHO.

builddeb: remove unneeded files in hdrobjfiles for headers package

2020-01-28T16:51:30+00:00

- We do not need tools/objtool/fixdep or tools/objtool/sync-check.sh
   for building external modules. Including tools/objtool/objtool is
   enough.

 - gcc-common.h is a check-in file. I do not see any point to search
   for it in objtree.
