d1ba71f764 sh64: oprofile: Fix up kernel stack pointer size mismatch.
For the backtrace code its assumed that the stack pointer is 32-bits,
which is not the case with the sh64 registers. Use the shared
kernel_stack_pointer() helper to get at the actual register, which
already takes care of the necessary typecasting.

0eff9f66de sh: Use the new stack unwinder API
Instead of implementing our own stack unwinder via dump_trace() we
should use the new stack unwinder API because it is more modular. This
change allows us to decouple the interface for generating stacktraces
from the implementation of a stack unwinder.

Copy the stacktrace ops code from x86 and provide a central function for
use by functions that need to dump a callstack.
