-This patch makes UP and SMP do the same thing as far as module per-cpu
-data go.
-
-Unfortunately it affects core code.
-
-To repeat the problem:
-  IA64 keeps per-cpu data in a small data area that is referenced by a
-  22-bit offset, for both UP and SMP cases.  If a module defines
-  per-cpu data, it too will end up in the small-data area.  But the
-  module loader at present special-cases the UP treatment of per-cpu
-  data, assumes that it is in the GP-relative data area, and does
-  nothing (for SMP it allocates space, and copies initialised data
-  items into it) 
-
-  The effect is that modules defining per-cpu data fail to load if
-  they're built UP, because of an impossible relocation.
-
-  The appended patch makes the treatment of per-cpu data uniform
-  between UP and SMP cases.  For most architectures, the per-cpu data
-  section will be empty for UP, and so the per-cpu setup code will not
-  be invoked.
