Yi Li	5bf9cbef99	Blackfin: update ftrace for latest toolchain ... The mcount support that was finally added to the Blackfin gcc port isn't exactly the same as what ftrace was developed against. Now that the final gcc version is in place, update the ftrace code to match. While updating this, fix the swapped arguments to the tracer (signature is (ip, parent_ip) while we were passing (parent_ip, ip)).

Mike Frysinger	1c873be744	Blackfin: initial support for ftrace ... Just the basic ftrace support here -- mcount and the ftrace stub. Signed-off-by: Mike Frysinger <vapier@gentoo.org>	2009-06-13 07:20:15 -04:00
Uwe Kleine-Koenig	c79a61f557	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.
