Still, IMHO, the series is in sufficient state to post and get the early feedback. The patches are build-tested with defconfig for most architectures (I couldn't find a compiler for nds32 and unicore32) and boot-tested on x86 VM. Mike Rapoport (29): mips: switch to NO_BOOTMEM mm: remove CONFIG_NO_BOOTMEM mm: remove CONFIG_HAVE_MEMBLOCK mm: remove bootmem allocator implementation. mm: nobootmem: remove dead code memblock: rename memblock_alloc{_nid,_try_nid} to memblock_phys_alloc* memblock: remove _virt from APIs returning virtual address memblock: replace alloc_bootmem_align with memblock_alloc memblock: replace alloc_bootmem_low with memblock_alloc_low memblock: replace __alloc_bootmem_node_nopanic with memblock_alloc_try_nid_nopanic memblock: replace alloc_bootmem_pages_nopanic with memblock_alloc_nopanic memblock: replace alloc_bootmem_low with memblock_alloc_low memblock: replace __alloc_bootmem_nopanic with memblock_alloc_from_nopanic memblock: add align parameter to memblock_alloc_node() memblock: replace alloc_bootmem_pages_node with memblock_alloc_node memblock: replace __alloc_bootmem_node with appropriate memblock_ API memblock: replace alloc_bootmem_node with memblock_alloc_node memblock: replace alloc_bootmem_low_pages with memblock_alloc_low memblock: replace alloc_bootmem_pages with memblock_alloc memblock: replace __alloc_bootmem with memblock_alloc_from memblock: replace alloc_bootmem with memblock_alloc mm: nobootmem: remove bootmem allocation APIs memblock: replace free_bootmem{_node} with memblock_free memblock: replace free_bootmem_late with memblock_free_late memblock: rename free_all_bootmem to memblock_free_all memblock: rename __free_pages_bootmem to memblock_free_pages mm: remove nobootmem memblock: replace BOOTMEM_ALLOC_* with MEMBLOCK variants mm: remove include/linux/bootmem.h arch/alpha/Kconfig | 2 -
