H. Peter Anvin 147dd5610c x86-32: Make sure we can map all of lowmem if we need to 
A relocatable kernel can be anywhere in lowmem -- and in the case of a
kdump kernel, is likely to be fairly high.  Since the early page
tables map everything from address zero up we need to make sure we
allocate enough brk that we can map all of lowmem if we need to.
