262 * Recursively walk the page table tree of the process represented by @walk->mm
263 * within the virtual address range [@start, @end). During walking, we can do
264 * some caller-specific works for each entry, by setting up pmd_entry(),
265 * pte_entry(), and/or hugetlb_entry(). If you don't set up for some of these
266 * callbacks, the associated entries/pages are just ignored.
267 * The return values of these callbacks are commonly defined like below:
