Perform a rototill of the powerpc code. Mandate use of SPRG0 to store a pointer to current cpu's cpu_info structure. Use cpu_info for intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on non-MULTIPROCESSOR machines. Add common macros GET_CPUINFO and INIT_CPUINFO to get and initialize the cpu_info struct on startup. Make ibm4xx use the standard <powerpc/frame.h>. Use IFRAME_xx in ibm4xx trap_subr.S instead of explicit magic offsets. Move INTSTK and SPILLSTK to std.<platform>. Change faultbuf to a struct instead of an array. On MPC6XX cpus, stop using the vector page for temporary space and use reserved space in cpu_info.

# $NetBSD: std.walnut,v 1.2 2003/02/02 20:43:18 matt Exp $
New umbrella-port for PowerPC-based evaluation boards. The first board to be included here is the port to the 405GP-based Walnut evaluation board, which up until now lived in arch/walnut. arch/walnut will go away soon, once all the remaining walnut-isms in the tree have been dealt with.
