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.
