Hi Badari,

This looks just fine to me.  Can you verify that "make Warn" compiles it
cleanly?  It looks like it should, but I don't have a ppc64 readily available.

Also, a minor nit -- for debug purposes only -- can you add this new
"ppc64_paca" size display to the dump_offset_table() routine -- just
under the "x8664_pda" size display?

Thanks,
  Dave
