Can I apply them in this order cleanly, without breaking bisection: > x86/mm: Rename tasksize_32bit/64bit to task_size_32bit/64bit > x86/mpx: Do not allow MPX if we have mappings above 47-bit > x86/mm: Prepare to expose larger address space to userspace > x86/mm: Allow userspace have mapping above 47-bit > x86: Enable 5-level paging support ? I.e. I'd like to move the first patch last. The reason is that we should first get all quirks and assumptions fixed, all facilities implemented - and only then enable 5-level paging as a final step which produces a well working kernel. (This should also make it slightly easier to analyze any potential regressions in earlier patches.)
