Helge Deller	11e178091f	parisc: add CALLER_ADDR{0-6} macros ... Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>	15 years ago
Helge Deller	d75f054a2c	parisc: add ftrace (function and graph tracer) functionality ... This patch adds the ftrace debugging functionality to the parisc kernel. It will currently only work with 64bit kernels, because the gcc options -pg and -ffunction-sections can't be enabled at the same time and -ffunction-sections is still needed to be able to link 32bit kernels.

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.
