Subject: next cleanup report:  "bad" references to CONFIG variables


  here's the next cleanup report that's well underway -- "bad"
references to CONFIG variables that don't exist in any Kconfig file:

  http://www.crashcourse.ca/wiki/index.php/Badref_CONFIG_variables

(currently, only the arch/ and drivers/ directories have been updated
-- the rest should be done shortly.)

  in a nutshell, that's a list of references to variables of the form
CONFIG_*, where there is no such variable defined anywhere in a
Kconfig file.  some possible reasons for that:

  1) leftover historical cruft
  2) simple typo
  3) someone's added code without adding the Kconfig infrastructure
     for it (annoyingly, there appears to be quite a lot of that)
  4) someone likes to name their macros with a "CONFIG_" prefix just
     to pollute the Kconfig namespace (argh)

in any event, it's all there (some of it starting to look awfully
familiar as the years go by).  as always, ignore the false positives.
