110: * Created for new host/processor technology.
111: * [90/03/26 23:51:11 rpd]
112: *
113: * Remove KERNEL_SERVER define. Cleanup.
114: * [89/08/02 dlb]
115: * Add IsLong specifiers to variable length arguments to info calls.
116: * [89/08/02 dlb]
117: * Add thread_depress_abort.
118: * [89/06/20 dlb]
119: *
120: * Add processor_set_{tasks,threads}, host_processor_sets,
121: * host_processor_set_priv.

132: *
133: * Split processor_set_default. Add task_assign_default and
134: * thread_assign_default.
135: * [88/12/21 dlb]
136: *
137: * Minor cleanups, add host_kernel_version.
138: * [88/12/02 dlb]
139: *
140: * Revision 2.4 89/12/22 15:54:26 rpd
141: * Under KERNEL_SERVER, pass the out arguments of
142: * processor_set_create as port_t's. They really are
143: * the appropriate processor set types, but processor_set_create
144: * does the type conversions internally. This isn't pretty.
145: * [89/12/15 dlb]
146: *
147: * Revision 2.3 89/10/15 02:05:40 rpd
