The i386 LDT code had it's own set of arch hooks (??_segments), I've
replaced most of them with the mmu context hooks in a previous patch.
The attached patch completes that change: replace release_segments with
destroy_context.

The patch is part of the -ac kernels in 2.4.  The patch breaks x86-64,
Andi Kleen promised to send you the corresponding
s/release_segments/destroy_context/ patch.
