Title:
  enable linux-crashdump on ppc64el

Status in “linux-meta” package in Ubuntu:
  Triaged

Bug description:
  SRU Justification:

  [Impact]
  Users of ppc64el hardware need the ability to use crashdumps to do kernel debugging.

  [Test Case]
  Taken from:
  https://wiki.ubuntu.com/Kernel/CrashdumpRecipe
  https://help.ubuntu.com/14.04/serverguide/kernel-crash-dump.html

  1) apt-get install linux-crashdump
  2) reboot the machine
  3) sudo sed -i 's/USE_KDUMP=0/USE_KDUMP=1/g' /etc/default/kdump-tools
  4) kdump-config show # should return no errors
  5) echo 'c' | sudo tee /proc/sysrq-trigger
  6) This should crash the machine and we should kexec into another kernel to dump the core, then on the next reboot we should see a crash in /var/crash/*

  [Regression Potential]
  Part of the fix involves adding a NEW package for ppc64el to allow linux-crashdump binary package to be built from linux-meta.
