While reviewing some other patches [1], Willy pointed out that lockless page-table walkers should probably be using the same magic for PMD as we do for PTE on things like i386-PAE. These patches are the result of that and apply on top of that earlier series. [1] https://lkml.kernel.org/r/20201126120114.071913521@infradead.org
