But ideally either the boot loader gives you space, or the platform boot code is smart enough to detect that there is insufficient room and puts the heap somewhere else. cheers _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
