This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
hirsute' to 'verification-done-hirsute'. If the problem still exists,
change the tag 'verification-needed-hirsute' to 'verification-failed-
hirsute'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  [Impact]

  Huge pages can't be managed via hugeadm which requires hugetlbfs.

  [Test Case]

  $ hugeadm --pool-list
  hugeadm:ERROR: kernel does not support huge pages

  With fix:
  $ hugeadm --pool-list
        Size  Minimum  Current  Maximum  Default
       65536        0        0        0
     2097152        0        0        0        *
    33554432        0        0        0
  1073741824        0        0        0

  [Fix]

  Enable CONFIG_HUGETLBFS

  [Regression Potential]

  This config enables code that is disabled by default. However, there
  is minimal stub code running at boot so problems would most likely
  show up as splats during boot or later on when hugetlbfs is explicitly
  mounted by systemd.
