These patches switch those architectures to use a generic implementation that does free_initmem_default(POISON_FREE_INITMEM). This was inspired by Christoph's patches for free_initrd_mem [1] and I shamelessly copied changelog entries from his patches :) v2: rebased on top of v5.0-rc7 + Christoph's patches for free_initrd_mem [1] https://lore.kernel.org/lkml/20190213174621.29297-1-hch@lst.de/ Mike Rapoport (4): init: provide a generic free_initmem implementation hexagon: switch over to generic free_initmem() init: free_initmem: poison freed init memory riscv: switch over to generic free_initmem() arch/alpha/mm/init.c | 6 ------ arch/arc/mm/init.c | 8 -------- arch/c6x/mm/init.c | 5 ----- arch/h8300/mm/init.c | 6 ------ arch/hexagon/mm/init.c | 10 ---------- arch/microblaze/mm/init.c | 5 ----- arch/nds32/mm/init.c | 5 ----- arch/nios2/mm/init.c | 5 ----- arch/openrisc/mm/init.c | 5 ----- arch/riscv/mm/init.c | 5 ----- arch/sh/mm/init.c | 5 ----- arch/sparc/mm/init_32.c | 5 ----- arch/unicore32/mm/init.c | 5 ----- arch/xtensa/mm/init.c | 5 ----- init/main.c | 5 +++++ 15 files changed, 5 insertions(+), 80 deletions(-) -- 2.7.4
