H. Peter Anvin acd644bb4a x86 setup: guard the heap against invalid stack setups 
If we use the bootloader-provided stack pointer, we might end up in a
situation where the bootloader (incorrectly) pointed the stack in the
middle of our heap.  Catch this by simply comparing the computed heap
end value to the stack pointer minus the defined stack size.
