I'm having trouble figuring out how to disable transparent hugepages without a reboot:

  ># uname -a
  Linux ip-10-214-7-159 3.2.0-36-virtual #57-Ubuntu SMP Tue Jan 8 22:04:49 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

  ># grep TRANSPARENT /boot/config-3.2.0-36-virtual
  CONFIG_TRANSPARENT_HUGEPAGE=y
  # CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS is not set
  CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y

  ># echo never > /sys/kernel/mm/transparent_hugepage/enabled
  bash: /sys/kernel/mm/transparent_hugepage/enabled: No such file or directory
