[PATCH] mmap topdown fix for large stack limit, large allocation
The topdown changes in 2.6.12-rc1 can cause large allocations with large
stack limit to fail, despite there being space available. The
mmap_base-len is only valid when len >= mmap_base. However, nothing in
topdown allocator checks this. It's only (now) caught at higher level,
which will cause allocation to simply fail. The following change restores
the fallback to bottom-up path, which will allow large allocations with
large stack limit to potentially still succeed.
