Looks like this hunk was originally added by commit id 'f2fc1eee' when
it was one huge chunk... I'm not overly familiar with how hugepages
work, but agree that it doesn't seem to cause ABI issues.

Looks like this hunk was added by commit id '136ad497' when the one
chunk was split with the extra mask capability. Again, I agree it
doesn't appear to cause ABI issues.
