Dear maintainer!

We have recently detected a kernel oops bug in the hugetlb code. The bug
is still present in the current linux-2.6 git branch (tested until [1]).
We have attached a 'git format-patch'-file that solved problem for us.
The commit message should describe the logic of the bug. Please contact
me if you have further questions or comments.

Sincerely,
Stefan Huber.
