Subject[PATCH -v2 00/10] Rewrite Motorola MMU page-table layout
Hi!

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

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

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

Michael tested the previous version on his Atari Falcon/68030.

Build tested for sun3/coldfire.

Please consider!

Changes since -v1:
- fixed sun3/coldfire build issues
- unified motorola mmu page setup
- added enum to table allocator
- moved pointer table allocator to motorola.c
- converted coldfire pgtable_t
- fixed coldfire pgd_alloc
- fixed coldfire nocache
