xtensa clears PTEs during allocation of the page tables and pte_clear() sets the PTE to a non-zero value. Splitting ptes_clear() helper out of pte_alloc_one() and pte_alloc_one_kernel() allows reuse of base generic allocation methods (__pte_alloc_one() and __pte_alloc_one_kernel()) and the common GFP mask for page table allocations. The pte_free() and pte_free_kernel() implementations on xtensa are identical to the generic ones and can be dropped.
