[PATCH] hugetlb_get_unmapped_area fix
hugetlb_get_unmapped_area() fails to find an unmapped area while unmapped area is huge. That's because hugetlb_get_unmapped_area just searches forward from mm->free_area_cache. If reaching TASK_SIZE, it does not go back to TASK_UNMAPPED_BASE, just returns -ENOMEM. 1) Add a specific hugetlb_get_unmapped_area on i386. 2) Generic hugetlb_get_unmapped_area is also fixed.
