ARM: 8747/1: make CONFIG_DEBUG_WX depend on MMU
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") Acked-by: Laura Abbott <labbott@redhat.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
