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. 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 --- arch/m68k/include/asm/mcf_pgalloc.h | 31 ++--- arch/m68k/include/asm/motorola_pgalloc.h | 74 ++++------ arch/m68k/include/asm/motorola_pgtable.h | 36 +++-- arch/m68k/include/asm/page.h | 16 ++- arch/m68k/include/asm/pgtable_mm.h | 10 +- arch/m68k/mm/init.c | 34 +++-- arch/m68k/mm/kmap.c | 36 +++-- arch/m68k/mm/memory.c | 103 -------------- arch/m68k/mm/motorola.c | 228 +++++++++++++++++++++++++------ 9 files changed, 302 insertions(+), 266 deletions(-)
