| |
Without a prompt string, it is impossible to disable FRAME_POINTER on ARM. It will simply set the default value anytime you run 'make'.
To reproduce the original issue, run: make multi_v7_defconfig scripts/config -d ARM_UNWIND make oldconfig # check .config, note that FRAME_POINTER=y scripts/config -d FRAME_POINTER make oldconfig # check .config, note that FRAME_POINTER is still y
