  32  * This header file should not exist.
  33  *
  34  * Whether it be due to laziness, machismo, or just plain cluelessness, most
  35  * of the symbols over in psm/stand are not properly prototyped anywhere.
  36  *
  37  * To workaround this, developers have adopted the horrendous practice of
  38  * "externing" the symbols they need, leading to dozens of declarations of
  39  * the same symbol which have to be kept in sync.  Unfortunately, no similar
  40  * workaround exists for lint's pass2, which requires definitions for all
  41  * symbols in order to properly perform cross-checks.
  42  *
  43  * Thus, this header file was created to address two problems:
  44  *
  45  *      1. The "extern" problem.  All files beneath stand/lib should #include
  46  *         this file rather than "extern" the symbol. Additionally, existing
  47  *         externs should be removed as convenient.
  48  *
  49  *         Of course, eventually some brave soul needs to venture over to the
  50  *         slums of psm/stand and add all the proper header files, at which
  51  *         point this file can be disposed of.
  52  *
  53  *      2. The lint pass2 problem.  Specifically, this file is used to build
  54  *         llib-lfakeboot.ln, which is then used to properly lint the
  55  *         binaries under stand/lib.  See stand/lib/llib-lfakeboot for more
  56  *         details.
  57  *
  58  * Note that the set of symbols shared between stand/lib and psm/stand is
  59  * itself a moving target.  As such, this file should be updated as needed
  60  * so that it always contains the *minimum* set of shared symbols needed to
  61  * avoid externs and placate lint.
