[ARM] 5386/2: unwind: Add Makefile and Kconfig entries for ARM stack unwinding
This patch also makes the frame pointer default to y only if !ARM_UNWIND. LOCKDEP no longer selects FRAME_POINTER if ARM_UNWIND is enabled. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
