Hi, These patches convert ia64 to use NO_BOOTMEM. The first two patches are cleanups, the third patches reduces usage of 'struct bootmem_data' for easier transition and the forth patch actually replaces bootmem with memblock + nobootmem. I've tested the sim_defconfig with the ski simulator and build tested other defconfigs. Mike Rapoport (4): ia64: contig/paging_init: reduce code duplication ia64: remove unused num_dma_physpages member from 'struct early_node_data' ia64: use mem_data to detect nodes' minimal and maximal PFNs ia64: switch to NO_BOOTMEM arch/ia64/Kconfig | 1 + arch/ia64/kernel/setup.c | 11 +++- arch/ia64/mm/contig.c | 75 +++----------------------- arch/ia64/mm/discontig.c | 134 ++++++----------------------------------------- 4 files changed, 33 insertions(+), 188 deletions(-) -- 2.7.4
