arm64: remove redundant FRAME_POINTER kconfig option and force to select it
FRAME_POINTER is defined in lib/Kconfig.debug, it is unnecessary to redefine it in arch/arm64/Kconfig.debug. ARM64 depends on frame pointer to get correct stack trace (also selecting ARCH_WANT_FRAME_POINTERS). However, the lib/Kconfig.debug definition allows such option to be disabled. This patch forces FRAME_POINTER always on on arm64. Signed-off-by: Yang Shi <yang.shi@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
