Title:
  CONFIG_PREEMPT is not set. Why?

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” source package in Trusty:
  Won't Fix

Bug description:
  Since the generic kernel is for generic desktop use CONFIG_PREEMPT
  should be set. CONFIG_NO_HZ is already there so it seems strange to me
  that preempt is not especially because recommendations for desktop
  system usually includes building a preemptible kernel.
