260 *
261 * Why all these "- 1"s? Because 0 represents both the bottom

263 * top wouldn't help much: the masks would do the wrong thing).
264 * The rule is that addr 0 and floor 0 refer to the bottom of

266 * Comparisons need to use "end - 1" and "ceiling - 1" (though
267 * that end 0 case should be mythical).
268 *
269 * Wherever addr is brought up or ceiling brought down, we
270 * must be careful to reject "the opposite 0" before it
271 * confuses the subsequent tests. But what about where end is
272 * brought down by HUGEPD_SIZE below? no, end can't go down to
273 * 0 there.
274 *
275 * Whereas we round start (addr) and ceiling down, by different
276 * masks at different levels, in order to test whether a table
277 * now has no other vmas using it, so can be freed, we don't
