From: David Miller on 13 Apr 2010 07:50 I've spent the last week or so getting ftrace et al. working again on sparc64. The NMI scheme I use there was causing all sorts of issues, but luckily the final fix was very simple. While I was here debugging this stuff I added function graph tracer support, as well as support for kmemleak. Kmemleak even found a bug :-) All combinations of features seems to work (perf top with tracers, lockdep, and kmemleak all enabled for example) and wow is this stuff super-useful :-) I merged in your tree to resolve a conflict in lib/Kconfig.debug since Microblaze added kmemleak support recently too. Please pull, thanks a lot!
