Fixing this means we properly look up huge page entries only when the Present bit is actually set in the PTE. Second, use the standard pte_alloc_map() instead of the hand-rolled pte_alloc_hugetlb() routine that basically was written to avoid worrying about CONFIG_HIGHPTE. However, we no longer plan to support HIGHPTE, so a separate routine was just unnecessary code duplication. Signed-off-by: Chris Metcalf --- Reading git-diff-tree failed
