Subject: [PATCH 01/09] clockevents: Remove CONFIG_GENERIC_CLOCKEVENTS_BUILD
Date: Wed, 25 Mar 2015 13:05:19 +0100	[thread overview]
Message-ID: <5021859.jl9OC1medj@vostro.rjw.lan> (raw)
In-Reply-To: <4241632.Wi7SZdKMQs@vostro.rjw.lan>

From: Thomas Gleixner <tglx@linutronix.de>

This option was for simpler migration to the clock events code. Most
architectures have been converted and the option has been
disfunctional as a standalone option for quite some time. Remove it.
