#     ia64: export node_distance function
#     
#     The numa_slit variable used by node_distance is available to a
#     module as long as it is linked at compile-time. However, it is
#     not available to loadable modules. Leading to errors such as:
#     
#       ERROR: "numa_slit" [drivers/nvme/host/nvme-core.ko] undefined!
#     
#     The error above is caused by the nvme multipath code that makes
#     use of node_distance for its path calculation. When the patch was
#     added, the lightnvm subsystem would select nvme and always compile
#     it in, leading to the node_distance call to always succeed.
#     However, when this requirement was removed, nvme could be compiled
#     in as a module, which exposed this bug.
#     
#     This patch extracts node_distance to a function and exports it.
#     Since ACPI is depending on node_distance being a simple lookup to
#     numa_slit, the previous behavior is exposed as slit_distance and its
#     users updated.
#     
#     Fixes: f333444708f82 "nvme: take node locality into account when selecting a path"
#     Fixes: 73569e11032f "lightnvm: remove dependencies on BLK_DEV_NVME and PCI"
