Subject: [PATCH v2 7/7] kbuild: use git-archive for source package creation
Commit 5c3d1d0abb12 ("kbuild: add a tool to list files ignored by git")
added a new tool, scripts/list-gitignored. My intention was to create
source packages without cleaning the source tree, without relying on git.
Linus strongly objected to it, and suggested using 'git archive' instead.
[1] [2] [3]
This commit goes in that direction - Remove scripts/list-gitignored.c
and rewrites Makefiles and scripts to use 'git archive' for building
Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg'
use 'git archive' again.
Going forward, building source packages is only possible in a git-managed
tree. Building binary packages does not require git.
