Without CONFIG_MMU, this results in a build failure:
./arch/arm/include/asm/memory.h:92:23: error: initializer element is not constant #define VECTORS_BASE vectors_base arch/arm/mm/dump.c:32:4: note: in expansion of macro 'VECTORS_BASE' { VECTORS_BASE, "Vectors" },
arch/arm/mm/dump.c:71:11: error: 'L_PTE_USER' undeclared here (not in a function); did you mean 'VTIME_USER'? .mask = L_PTE_USER, ^~~~~~~~~~
Obviously the feature only makes sense with an MMU, so let's add the dependency here.
