Hi!
In order to faciliate Will's READ_ONCE() patches:
https://lkml.kernel.org/r/[email protected]
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

Thanks for the quick turn around. Build looks good for me too with
this new series. I will test on real hardware on Monday.

So this tests good for me on real hardware. I had a look over the
ColdFire changes and I have no problems with anything.
So for the ColdFire parts:

Thanks, applied and queued for v5.7, using an immutable branch named
pgtable-layout-rewrite.

Any plans to use this? Looks like it's still part of linux-next through the m68k
tree only.

Argh, yes. So we ran into sparc32 also need fixups, and both me and Will
seem to have stalled on fixing that. I'll try and get back to that.
