* HISTORY
* $Log: mach.defs,v $
* Revision 2.15 93/01/21 12:23:14 danner
* New interface for task_ras_control.
* [93/01/19 16:35:06 bershad]
*
* Revision 2.14 92/07/20 13:33:09 cmaeda
* Added definition for task_set_ras_pc.
* Uses message number recycled from old task_get_io_port.
* [92/05/11 14:37:53 cmaeda]
*
* Revision 2.13 92/01/15 13:45:00 rpd
* Changed MACH_IPC_COMPAT conditionals to default to not present.
*
* Revision 2.12 92/01/14 16:45:18 rpd
* Changed mach_port_array_t usages to remain compatible,
* because the definition of the type changed incompatibly.
* [92/01/13 rpd]
* Updated vm_region for new memory_object_name_t definition.
* [91/12/31 rpd]
*
* Revision 2.11 92/01/03 20:20:53 dbg
* Changed (new) task_get_emulation_vector,
* task_set_emulation_vector to pass data out-of-line. Old
* routines still pass data in-line, for compatibility.
* [92/01/03 dbg]
*
* Add 'CountInOut' tag to routines returning variable-length
* inline arrays. Remove 'IsLong' tag from routines passing or
* returning variable-length arrays. Old routines left under
* 'xxx_' names. REMOVE THESE SOON!
*
* I used the message IDs from the Mach 1.5 thread calls (before
* the real thread support went in) - they haven't been used since
* 1988.
* [91/11/26 dbg]
*
* Revision 2.10 91/08/28 11:15:04 jsb
* Precious page support: Add new version of memory_object_lock_request.
* Add memory_object_{ready,change_attributes}.
* [91/07/03 14:03:34 dlb]
* Added KERNEL_USER definitions (for NORMA support).
* [91/08/15 09:58:13 jsb]
*
* Revision 2.9 91/07/31 17:53:17 dbg
* Added user-settable 'dealloc' flag to data argument of
* memory_object_data_supply. Needs new MiG.
* USERS OF THIS FUNCTION MUST RE-LINK!!
* [91/07/29 dbg]
*
* MACH_IPC_COMPAT: set C type for backup argument to
* port_set_backup to be 'mach_port_t'. If mach_interface.h is
* included with MACH_IPC_COMPAT == 0, the type 'port_t' is not
* defined.
*
* Removed vm_pageable.
* [91/06/24 dbg]
*
* Revision 2.8 91/07/01 08:25:09 jsb
* From David Black at OSF: added memory_object_data_supply.
* [91/06/29 14:59:47 jsb]
*
* Revision 2.7 91/06/06 17:07:51 jsb
* Added task_get_emulation_vector, task_set_emulation_vector.
* [91/05/24 18:26:01 jsb]
*
* Revision 2.6 91/05/14 16:54:18 mrt
* Correcting copyright
*
* Revision 2.5 91/02/05 17:33:12 mrt
* Changed to new Mach copyright
* [91/02/01 17:17:41 mrt]
*
* Revision 2.4 90/06/02 14:58:09 rpd
* Changed reply_to argument of memory_object_lock_request
* to default to a send-once right but still allow send rights.
* [90/05/31 rpd]
*
* Changes for the emulator: remove vm_allocate, redefine vm_map.
*
* Obsoleted vm_allocate_with_pager.
* [90/04/08 rpd]
* Converted to new IPC. Purged MACH_NP, MACH_NET.
* Moved vm_set_default_memory_manager, memory_object_get_attributes.
* [90/03/26 22:31:41 rpd]
*
*
* Condensed history:
* Added vm_machine_attribute (af).
* Added memory_object_get_attributes (mwyoung).
* Added vm_set_default_memory_manager (mwyoung).
* Added thread_set_priority (dbg).
* Added vm_pageable (dbg).
* Added port_set_backup (rpd).
* Added memory_object_destroy (mwyoung).
* Converted to memory_object_* names (mwyoung).
* New port and port set calls (rpd).
* Added documentation (mwyoung).
* Added vm_map, pager_attributes, pager_data_error (mwyoung).
* Added task_set_emulation and task_get_io_port (dorr).
* Added new thread and task interfaces (dbg).
* Reset history (avie).
