Your port looks relatively clean but it looks like it is borrowing heavily from the mips port and you may have a few leftovers from that e.g.: - mentions of o32 (unless S+CORE has an o32 ABI?) - compatibility syscalls, sys_ipc, old-style signal handling. Are these really needed for a new arch? - does SCORE+ have ll/sc instructions or is that another leftover from MIPS? - does your port support SMP? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
