If so, apply handling 571.36Spalle to all of them now 581.36Spalle - consider method used by Solaris/OpenSolaris/Illumos (look for PROM_32BIT_ADDRS in 591.36Spalle the Illumos codebase) 601.27Spalle - platforms tested so far: 611.33Spalle -- qemu sun4v/niagara - reaches the point where the kernel needs to mount a root fs 621.27Spalle -- T2000 - mmu fault somewhere 631.27Spalle -- T5 - stickcmpr is not properly initialized ??? 64
