So that we pass a same-page range to tb_invalidate_phys_page_range, instead of always passing an end address that could be on a different page. As discussed with Peter Maydell on the list [1], tb_invalidate_phys_page_range doesn't actually do much with 'end', which explains why we have never hit a bug despite going against what the comment on top of tb_invalidate_phys_page_range requires: > * Invalidate all TBs which intersect with the target physical address range > * [start;end[. NOTE: start and end must refer to the *same* physical page. The appended honours the comment, which avoids confusion. While at it, rework the loop into a for loop, which is less error prone (e.g. "continue" won't result in an infinite loop).
