From c417fbce98722ad7e384caa8ba6f2e7c5f8672d9 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 26 Jun 2018 01:40:23 +0900 Subject: kbuild: move bin2c back to scripts/ from scripts/basic/ Commit 8370edea81e3 ("bin2c: move bin2c in scripts/basic") moved bin2c to the scripts/basic/ directory, incorrectly stating "Kexec wants to use bin2c and it wants to use it really early in the build process. See arch/x86/purgatory/ code in later patches." Commit bdab125c9301 ("Revert "kexec/purgatory: Add clean-up for purgatory directory"") and commit d6605b6bbee8 ("x86/build: Remove unnecessary preparation for purgatory") removed the redundant purgatory build magic entirely. That means that the move of bin2c was unnecessary in the first place. fixdep is the only host program that deserves to sit in the scripts/basic/ directory.
