We use the kernel command line to do reservation of hugetlb pages. The code
duplcation here is mostly to make it simpler. With 64 bit book3s, we need to
support either 16G or 1G gigantic hugepage. Whereas the FSL_BOOK3E
implementation needs to support multiple gigantic hugepage. We avoid the
gpage_
