[PATCH 0/5] Rewrite Motorola MMU page-table layout

[Peter Zijlstra]

Hi!

In order to faciliate Will's READ_ONCE() patches:

  https://lkml.kernel.org/r/20200123153341.19947-1-will@xxxxxxxxxx

we need to fix m68k/motorola to not have a giant pmd_t. These patches do so and
are tested using ARAnyM/68040.

It would be very good if someone can either test or tell us what emulator to
use for 020/030.

Please consider.
