As Matthew pointed out [1], many architectures put their definition of virt_to_phys() in asm/io.h, e.g. arch/powerpc/include/asm/io.h:#define virt_to_phys virt_to_phys arch/sh/include/asm/io.h:#define virt_to_phys(address) ((unsigned long)(address)) arch/x86/include/asm/io.h:#define virt_to_phys virt_to_phys which means memblock needs this header for declaration of virt_to_phys(). Although it is included indirectly, let's keep it for now.
