The current code in ftrace_regs_caller() doesn't assign %r3 to contain the address of the current frame. This is hidden if the kernel is compiled with FRAME_POINTER, but without it just crashes because it tries to dereference an arbitrary address. Fix this by always setting %r3 to the current stack frame. Signed-off-by: Sven Schnelle <svens@stackframe.org> Signed-off-by: Helge Deller <deller@gmx.de>
