Message-ID: <tip-3120e25efdc0834c88e1c0f8394e2087444f8c19@git.kernel.org> Date: Thu, 13 Sep 2012 23:24:22 -0700 From: tip-bot for Jan Beulich <JBeulich@...e.com> To: linux-tip-commits@...r.kernel.org Cc: linux-kernel@...r.kernel.org, hpa@...or.com, mingo@...nel.org, torvalds@...ux-foundation.org, jbeulich@...e.com, JBeulich@...e.com, tglx@...utronix.de Subject: [tip:x86/build] x86/Kconfig: Clean up Kconfig defaults Commit-ID: 3120e25efdc0834c88e1c0f8394e2087444f8c19 Gitweb: http://git.kernel.org/tip/3120e25efdc0834c88e1c0f8394e2087444f8c19 Author: Jan Beulich <JBeulich@...e.com> AuthorDate: Mon, 10 Sep 2012 12:41:45 +0100 Committer: Ingo Molnar <mingo@...nel.org> CommitDate: Thu, 13 Sep 2012 17:45:33 +0200 x86/Kconfig: Clean up Kconfig defaults The main goal here is to have the resulting .config no carry any options that aren't enabled and can't be (i.e such where the default is "no" and can't be changed), so that if any such option later gets a user visible prompt, the user will actually be prompted on a "make ...oldconfig" rather than keeping the previously invisible option disabled. There's a little bit of other trivial cleanup mixed in here.
