[GIT] Sparc

[David Miller <davem@davemloft.net>]

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!
