Subject: [PATCH 12/12] get_unmapped_area doesn't need hugetlbfs hacks anymore
Date: Tue, 24 Apr 2007 15:33:40 +1000	[thread overview]
Message-ID: <20070424053342.63371DDF07@ozlabs.org> (raw)
In-Reply-To: <1177392813.924664.32930750763.qpush@grosgo>

Remove the hugetlbfs specific hacks in toplevel get_unmapped_area() now
that all archs and hugetlbfs itself do the right thing for both cases.
