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

From: Kevin Hilman <khilman@...aro.org>

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.
