| |
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
