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,

Ingo
