From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Hi, SPARSEMEM memory model was supposed to entirely replace DISCONTIGMEM a (long) while ago. The last architectures that used DISCONTIGMEM were updated to use other memory models in v5.11 and it is about the time to entirely remove DISCONTIGMEM from the kernel. This set removes DISCONTIGMEM from alpha, arc and m68k, simplifies memory model selection in mm/Kconfig and replaces usage of redundant CONFIG_NEED_MULTIPLE_NODES and CONFIG_FLAT_NODE_MEM_MAP with CONFIG_NUMA and CONFIG_FLATMEM respectively. I've also removed NUMA support on alpha that was BROKEN for more than 15 years. There were also minor updates all over arch/ to remove mentions of DISCONTIGMEM in comments and #ifdefs.
Hi Mike and Andrew, It looks like everyone is happy with this version so far. How should we merge it for linux-next? I'm happy to take it through the asm-generic tree, but linux-mm would fit at least as well. In case we go for linux-mm, feel free to add Acked-by: Arnd Bergmann <arnd@xxxxxxxx> for the whole series.
