Chen, Kenneth W 0e5c9f39f6 [PATCH] remove hugetlb_clean_stale_pgtable() and fix huge_pte_alloc() ... I don't think we need to call hugetlb_clean_stale_pgtable() anymore in 2.6.13 because of the rework with free_pgtables(). It now collect all the pte page at the time of munmap. It used to only collect page table pages when entire one pgd can be freed and left with staled pte pages. Not anymore with 2.6.13. This function will never be called and We should turn it into a BUG_ON. I also spotted two problems here, not Adam's fault :-) (1) in huge_pte_alloc(), it looks like a bug to me that pud is not checked before calling pmd_alloc() (2) in hugetlb_clean_stale_pgtable(), it also missed a call to pmd_free_tlb. I think a tlb flush is required to flush the mapping for the page table itself when we clear out the pmd pointing to a pte page. However, since hugetlb_clean_stale_pgtable() is never called, so it won't trigger the bug.
