variable mp_ncpu

Would it be possible to have the sysclt hw.ncpu 
always available, even in a UP kernel?

it is currently only valid in an SMP kernel
whichmeans that userland code that needs to know this has to do:

if (hw.ncpu exists)
  something(hw.ncpu)
else
  something(1)

having it always available would see a lot more consistant.
