The pte_alloc_one_kernel() function allocates a page using __get_free_page(GFP_KERNEL) when mm initialization is complete and memblock_phys_alloc() on the earlier stages. The physical address of the page allocated with memblock_phys_alloc() is converted to the virtual address and in the both cases the allocated page is cleared using clear_page(). The code is simplified by replacing __get_free_page() with get_zeroed_page() and by replacing memblock_phys_alloc() with memblock_alloc().
