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.
