    Subject2.4.3-pre7 and p*_alloc
    Hi,

    I'm looking at re-implementing the ARM page table allocation macros
    required for 2.4.3-pre7, and have found the following:

    pte_t *pte_alloc(struct mm_struct *mm, pmd_t *pmd, unsigned long address)
    {
    if (!pmd_present(*pmd)) {

    Why do we use pmd_present here instead of pmd_none? The same question
    applies to __pmd_alloc.
