#     powerpc/book3s64/hash/4k: 4k supports only 16TB linear mapping
#     
#     With commit: 0034d395f89d ("powerpc/mm/hash64: Map all the kernel
#     regions in the same 0xc range"), we now split the 64TB address range
#     into 4 contexts each of 16TB. That implies we can do only 16TB linear
#     mapping. Make sure we don't add physical memory above 16TB if that is
#     present in the system.
#     
#     Fixes: 0034d395f89d ("powerpc/mm/hash64: Map all the kernel regions in thesame 0xc range")
