  Hi Linus,

Please pull these execve updates for v6.2-rc1. Most are small
refactorings and bug fixes, but three things stand out: switching timens
(which got reverted before) looks solid now, FOLL_FORCE has been removed
(no failures seen yet across several weeks in -next), and some
whitespace cleanups (which are long overdue). The latter does end up
conflicting with changes from Al[1], but should be trivial to resolve.

Thanks!

-Kees
