This patch does the compat_sys_ptrace conversion for parisc.
In addition it does convert the parisc ptrace code to use the
architecture-independent ptrace infrastructure instead of own coding.

The unwinder was being initialized way too late to be any use
debugging early boot crashes. Instead of relying on module_init
initcalls to initialize it, let's do it explicitly as early as
we can.

These functions are called only when bringing up the monarch cpu,
so it is safe to call them without taking the pdc spinlock. In the
future, this may become relevant for lockdep, since these functions were
taking spinlocks before start_kernel called the lockdep initializers.
