* HISTORY
* 19-Mar-90 Gregg Kellogg (gk) at NeXT
* Made variable definitions extern. Panicstr is const char *.
*
* 27-Sep-89 Morris Meyer (mmeyer) at NeXT
* NFS 4.0 Changes: added dump_vp (so we can get core dumps working)
* removed extranious cruft from 3.2 port.
*
* 11-Aug-87 Peter King (king) at NeXT
* SUN_VFS: Added *rootvp and *specvp for the nfs routines.
* Added *bdevp for the specfs routines.
*
* 19-Mar-87 Avadis Tevanian (avie) at Carnegie-Mellon University
* Make redefinitions of insque/remque always ifdef'ed on lint.
*
* 24-Sep-86 Michael Young (mwyoung) at Carnegie-Mellon University
* Changed to directly import declaration of boolean.
*
* 29-Aug-86 Michael Young (mwyoung) at Carnegie-Mellon University
* Converted from "bool" type to "boolean_t" where necessary.
*
* 4-Nov-85 Avadis Tevanian (avie) at Carnegie-Mellon University
* Add sy_parallel flag to the system call entries to specify
* whether or not the system call can be executed in parallel.
*
* 03-Aug-85 Mike Accetta (mja) at Carnegie-Mellon University
* CS_RPAUSE: Added rpause() and fspause() declarations.
