Hi All,

I'm about to compile a new kernel and running oldconfig brings up this new set 
of options.  There is no help available, grep-ping through the Documentation 
wasn't particularly revealing and I haven't found anything in Google to help 
me decide what I need/want out of the three:
===================================================

* CPU/Task time and stats accounting
*
Cputime accounting
  1. Simple tick based cputime accounting (TICK_CPU_ACCOUNTING)
> 2. Full dynticks CPU time accounting (VIRT_CPU_ACCOUNTING_GEN) (NEW)
  3. Fine granularity task level IRQ time accounting (IRQ_TIME_ACCOUNTING)
choice[1-3]: ?

There is no help available for this option.
Prompt: Cputime accounting
  Location:
    -> General setup
      -> CPU/Task time and stats accounting
  Defined at init/Kconfig:297
  Selected by: m
===================================================

Option 2 seems to have been selected by default, but I am not sure if this is 
right for a laptop.

What have you chosen and why?

Mick
