    Subject[patch 08/10] Fix IPL from NSS.
    From: Heiko Carstens <>

    IPL from NSS didn't work because the memory detection routine omits any
    memory sections with a size lower than what MAX_ORDER defines.
    This causes the detection routine to skip the first memory segment which
    has a size of 1MB. Which later on will let the kernel think that there
    is no memory available at all.
    Since in addition the z/VM memory increment size is 1MB force MAX_ORDER
    to be 9, so we can support 1MB segments.
