Building a kernal from offial sources.

[John Turnbull <johnrt@home.com>]

I am obliged to build a new kernel that has been patched for ntp
pulse-per-second timing. To do this you need to use the official kernel
sources from www.kernel.org at specific patch levels. Now I expect that
the standard Intel kernel incantation will not cut it in Spark 2 land.
What do I need to change in the standard:

  make mrproper
  make xconfig
  make dep
  make bzImage
  make install
  make modules
  make modules_install

to make a kernel on a Spark 2?  John T
