Author: Milton Miller <miltonm@bga.com> On large machines we are running out of room below 256MB. 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).
