From: Grygorii Strashko <grygorii.strashko@xxxxxx> Commit 364230b9 "ARM: use phys_addr_t for DMA zone sizes" changes type of arm_dma_zone_size to phys_addr_t, but misses to update external definition of it in in arch/arm/include/asm/dma.h. As result, kernel build is failed if CONFIG_ZONE_DMA is enabled: arch/arm/mm/init.c:202:13: error: conflicting types for 'arm_dma_zone_size' include/linux/bootmem.h:258:66: note: previous declaration of 'arm_dma_zone_size' was here Hence, fix external definition of arm_dma_zone_size.
