69: * Added conditionalized sequence number support.
70: * [91/08/13 rpd]
71: *
72: * Revision 2.7 91/07/01 08:25:22 jsb
73: * If KERNEL and NORMA_VM, then use a userprefix (to allow interposition).
74: * [91/06/29 16:35:53 jsb]
75: *
76: * Revision 2.6 91/06/25 10:30:41 rpd
77: * Changed the port-based type declarations
78: * to use mach_port_t as the C type name.

96: *
97: * Revision 2.1 89/08/03 17:18:28 rwd
98: * Created.
99: *
100: * Revision 2.3 89/02/25 18:38:29 gm0w
101: * Changes for cleanup.
102: *
103: * Revision 2.2 89/01/15 16:31:26 rpd

116: *
117: * Revision 2.5 88/08/06 18:23:00 rpd
118: * Added dealloc flag to new_memory_object arg of memory_object_create().
119: * Otherwise, kernel_task is left with send right, and this is very bad.
120: *
121: * 29-Jun-88 Michael Young (mwyoung) at Carnegie-Mellon University
122: * Use new types.
123: *
124: * 29-Jun-88 Michael Young (mwyoung) at Carnegie-Mellon University
125: * Moved data type declarations to "mach_types.defs".
126: *
