Change 54701 by marcel@marcel_nfs on 2004/06/12 06:07:25

	Add a prototype of gdb_cpu_frame(). The function will return
	a filled-in trapframe given a struct thread. The implementation
	will be in md_${ARCH}.c so that we can deal with the various
	MD quirks.
	
	Add a next pointer to struct kthr and also save the kernel
	address of the corresponding struct thread there.
