dump_stack() just calls show_stack() with hardcoded arguments on most
architectures.

The sparc32 specific dump_stack function is missing, but there is a
show_stack in arch/sparc/kernel/process.c. Should it be easy enough to
connect these together, or are there known bugs that prevent the use of
dump_stack?

This adds a sparc32 specific dump_stack() to 2.6, based off of the sparc64
version.
