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.
Fixes: a8e53c151fe7 ("ARM: 8737/1: mm: dump: add checking for writable and
executable")
