[PATCH 01/09] clockevents: Remove CONFIG_GENERIC_CLOCKEVENTS_BUILD

From: Rafael J. Wysocki
Date: Wed Mar 25 2015 - 07:50:43 EST


From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

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.
