Revision bdab125c9301a6ac538911ba68f665dfd075ec81 authored by Masahiro Yamada on 19 June 2018, 09:43:41 UTC, committed by Ingo Molnar on 21 June 2018, 10:55:05 UTC
Reverts the following commit: b0108f9e93d0 ("kexec: purgatory: add clean-up for purgatory directory") ... which incorrectly stated that the kexec-purgatory.c and purgatory.ro files were not removed after 'make mrproper'. In fact, they are. You can confirm it after reverting it. $ make mrproper $ touch arch/x86/purgatory/kexec-purgatory.c $ touch arch/x86/purgatory/purgatory.ro $ make mrproper CLEAN arch/x86/purgatory $ ls arch/x86/purgatory/ entry64.S Makefile purgatory.c setup-x86_64.S stack.S string.c This is obvious from the build system point of view. arch/x86/Makefile adds 'arch/x86' to core-y. Hence 'make clean' descends like this: arch/x86/Kbuild -> arch/x86/purgatory/Makefile Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Michal Marek <michal.lkml@markovi.net> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/lkml/1529401422-28838-2-git-send-email-yamada.masahiro@socionext.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
