tracing: make CALLER_ADDRx overwriteable The current definition of CALLER_ADDRx isn't suitable for all platforms. E.g. for ARM __builtin_return_address(N) doesn't work for N > 0 and AFAIK for powerpc there are no frame pointers needed to have a working __builtin_return_address. This patch allows defining the CALLER_ADDRx macros in <asm/ftrace.h> and let these take precedence. Because now <asm/ftrace.h> is included unconditionally in <linux/ftrace.h> all archs that don't already had this include get an empty one for free.
