[PATCH 3/3] ARM: Kconfig: allow full nohz CPU accounting

From: Frederic Weisbecker
Date: Wed Oct 02 2013 - 08:38:15 EST


From: Kevin Hilman <khilman@xxxxxxxxxx>

With the 64-bit requirement removed from VIRT_CPU_ACCOUNTING_GEN,
allow ARM platforms to enable it. Since VIRT_CPU_ACCOUNTING_GEN is a
dependency for full NO_HZ, this allows ARM platforms to enable full
NO_HZ as well.
