[...] #define GV_HPAGE_SHIFT (GV_PGIDX_SZ_LG2 - GV_GRPS_PPG_LG2) [...] calculates out as (3 - (12 - 5 + 3)))), or -1. Oooh. After finally diving into Motorola's multi-thousand-pages PPC manuals, I found rlwinm to be a bit shift operator and the third parameter is the number of bits to be shifted. This is a 5-bit parameter, so 31 == -1. It's a compiler missing feature/bug. After redefining GV_HPAGE_SHIFT in osfmk/ppc/mappings.h to 31 (works for now) and a "make clean; make" the compile completed. Two missing symbols in the final link stage left for enjoyment tomorrow.
