[SPARC]: dump_stack for sparc
Bob Breuer wrote a patch to add dump_stack for sparc. Supposedly, this was applied, but it doesn't exist in 2.6.11. This is the same patch, rediffed against 2.6.11. Signed-off-by: Tom 'spot' Callaway <tcallawa@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
