[PATCH] hugetlb consolidation
From: William Lee Irwin III <wli@holomorphy.com>
The following patch consolidates redundant code in various hugetlb
implementations. I took the liberty of renaming a few things, since the
code was all moved anyway, and it has the benefit of helping to catch
missed conversions and/or consolidations.
