/*
* HISTORY
* $Log: memory_object_default.defs,v $
* Revision 2.8 91/08/28 11:15:24 jsb
* Added conditionalized sequence number support.
* [91/08/13 rpd]
*
* Revision 2.7 91/07/01 08:25:22 jsb
* If KERNEL and NORMA_VM, then use a userprefix (to allow interposition).
* [91/06/29 16:35:53 jsb]
*
* Revision 2.6 91/06/25 10:30:41 rpd
* Changed the port-based type declarations
* to use mach_port_t as the C type name.
* [91/05/23 rpd]
*
* Revision 2.5 91/05/14 16:56:08 mrt
* Correcting copyright
*
* Revision 2.4 91/02/05 17:34:05 mrt
* Changed to new Mach copyright
* [91/02/01 17:19:22 mrt]
*
* Revision 2.3 90/08/06 17:06:16 rpd
* For compatibility with Mach 2.5, added dealloc to
* argument of memory_object_create.
* [90/08/04 rpd]
*
* Revision 2.2 90/06/02 14:59:00 rpd
* Converted to new IPC.
* [90/03/26 22:35:46 rpd]
*
* Revision 2.1 89/08/03 17:18:28 rwd
* Created.
*
* Revision 2.3 89/02/25 18:38:29 gm0w
* Changes for cleanup.
*
* Revision 2.2 89/01/15 16:31:26 rpd
* Moved from kern/ to mach/.
* [89/01/15 14:40:47 rpd]
*
* Revision 2.7 89/01/12 07:58:30 rpd
* Fixed includes.
* [89/01/12 04:52:50 rpd]
*
* Revision 2.6 88/08/25 18:17:23 mwyoung
* Rid the kernel_task of rights to the new memory_object in
* memory_object_create.
* Add size argument to memory_object_create.
* [88/08/11 18:47:16 mwyoung]
*
* Revision 2.5 88/08/06 18:23:00 rpd
* Added dealloc flag to new_memory_object arg of memory_object_create().
* Otherwise, kernel_task is left with send right, and this is very bad.
*
* 29-Jun-88 Michael Young (mwyoung) at Carnegie-Mellon University
* Use new types.
*
* 29-Jun-88 Michael Young (mwyoung) at Carnegie-Mellon University
* Moved data type declarations to "mach_types.defs".
*
* 9-Dec-87 Michael Young (mwyoung) at Carnegie-Mellon University
