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 # # Signed-off-by: Aneesh Kumar K.V # Signed-off-by: Michael Ellerman #
