Message-Id: <1414101372-14443-14-git-send-email-alexis.berlemont@gmail.com>
Date: Thu, 23 Oct 2014 23:56:11 +0200
From: Alexis Berlemont <alexis.berlemont@...il.com>
To: linux-kernel@...r.kernel.org
Cc: Alexis Berlemont <alexis.berlemont@...il.com>, jolsa@...hat.com
Subject: [PATCH v2 13/14] perf kbuild: final cosmetic changes
* Correctly rename internal makefile variables
* Remove makefiles in tools/perf/config which became empty and useless
* Remove builtin-cmds.h
* Remove arch/x86/Makefile
* Improve outputs of clean and install targets
* Remove creation of PERF-FEATURES file which is redundant with the
.config file generated by Kconfig.
* replace HAVE_KVM_STAT_SUPPORT by a Kconfig option
* replace HAVE_SKIP_CALLCHAIN_IDX by a Kconfig option
