ARM: Kconfig: allow full nohz CPU accounting

Kevin Hilman · fweisbec · commit 31c1fc818715 · 2013-09-30T15:37:05.000+02:00
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.
