#     powerpc/mm: Increase the max addressable memory to 2PB
#     
#     Currently we limit the max addressable memory to 128TB. This patch increase the
#     limit to 2PB. We can have devices like nvdimm which adds memory above 512TB
#     limit.
#     
#     We still don't support regular system ram above 512TB. One of the challenge with
#     that is the percpu allocator, that allocates per node memory and use the max
#     distance between them as the percpu offsets. This means with large gap in
#     address space ( system ram above 1PB) we will run out of vmalloc space to map
#     the percpu allocation.
#     
#     In order to support addressable memory above 512TB, kernel should be able to
#     linear map this range. To do that with hash translation we now add 4 context
#     to kernel linear map region. Our per context addressable range is 512TB. We
#     still keep VMALLOC and VMEMMAP region to old size. SLB miss handlers is updated
#     to validate these limit.
#     
#     We also limit this update to SPARSEMEM_VMEMMAP and SPARSEMEM_EXTREME
