  using hugepages/hugepagesz causes kexec'd kernel to OOM

Bug description:
  [Impact]
  Users of kdump won't be able to dump if their system uses 
hugepages/hugepagesz on the cmdline.

  [Test Case]
  1) Install crashdump
  2) Boot machine with hugepages= or hugepagesz= set to a significant amount of 
memory
  3) Try to crash with 'echo 'c' | sudo tee /proc/sysrq-trigger'

  [Regression Potential]
  If users really want to have hugepages/hugepagesz on the kexec'd kernel for 
kdump they can add this via KDUMP_CMDLINE_APPEND in /etc/default/kdump-tools.
  This patch should also potentially go upstream.
