In some cases we only need to ensure the allocation is in the first segment, which may be 256MB or 1TB. Add slb0_limit and use it to specify the upper limit for the irqstack and emergency stacks. On a large ppc64 box, this fixes a panic at boot when the crashkernel= option is specified (previously we would run out of memory below 256MB).
