Thanks, I will study the code again, and try to find What we need to do
with the reservation code.

Okay, I will try to implement the full featured giga pages support. :)

But I feel confused at the "full featured". If the patch set can pass
all the giga pages tests in the libhugetlbfs, can we say it is "full
featured"? Or some one reviews this patch set, and say it is full
featured support for the giga pages.
