Something like" Improved PAGE_EXEC flag handling"?
It makes sure that referenced pages are not automatically marked executable by QEMU (despite the XI bit). As a user-visible change, this might unbreak some tests that attempt to execute data. Note that this fix does not affect pages that are not referenced prior to being executed - those have worked fine. Otherwise for normal code that does not attempt to execute data, things should not change at all.
