ifdefing inclusion of <asm/mem_access.h> in <xen/mem_access.h> allows to avoid generation of empty <asm/mem_access.h> header for the case when !CONFIG_MEM_ACCESS. For Arm it was explicitly added inclusion of <asm/mem_access.h> for p2m.c and traps.c because they require some functions from <asm/mem_access.h> which aren't available in case of !CONFIG_MEM_ACCESS.
