OK, someone throw me a frickin bone here.    I can't, for love nor
money, find a way to get a vmlinux-uncompressed-with-symbols
  image for oprofile to use with my running F10 kernel.  They ship
kernel images compressed, and without symbols, and the older
  information on this (ca FC6) doesn't appear to work anymore--there's
no "core-debuginfo" and "kernel-debuginfo" packages to
  install.

So, to a first approximation, oprofile is next-to-useless for me. 
(Although it does helpfully tell me that the kernel and libgnuradio-core
  are the top two CPU users, but I'd really like more detail than that
:-) ).
