ARM: 8372/1: KGDB does not build on BE32
KGDB requires code patching, which only works on little-endian or newer big-endian (BE8) machines but not on the older big-endian ones (BE32) where it results in this build error: arch/arm/kernel/patch.c: In function '__patch_text_real': arch/arm/kernel/patch.c:93:4: error: implicit declaration of function '__opcode_to_mem_thumb32' [-Werror=implicit-function-declaration] insn = __opcode_to_mem_thumb32(insn); This adds a Kconfig dependency to avoid the broken case and for all other symbols that require code patching. Fixes: 23a4e4050ba9 ("arm: kgdb: Handle read-only text / modules") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
