Why cannot we simply select it and its dependencies, explicitly, for the 
time being? Something like:

	depends on 64BIT
	select VIRT_CPU_ACCOUNTING
	select VIRT_CPU_ACCOUNTING_GEN

90% of the .config's have VIRT_CPU_ACCOUNTING_GEN turned off, because it's 
a default-off feature - so dynticks-full is effectively hidden from the 
large majority of testers...

Thanks,
