Wed Feb 12 16:22:07 1997  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* kernel/kern/debug.c (panic): Insert a delay loop.  Do a reboot
	instead of a mere halt.

Wed Feb  5 12:07:30 1997  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* kernel/util/cpu.h (struct cpu): Add dummy field so that zero
	size structure doesn't become an undefined variable.

	* kernel/version.c: New file.

	* kernel/kern/elf-load.c: New file.  (Was mach4/libmach/exec/elf.c
	in Utah distribution.)  Define exec_load instead of exec_load_elf.

	* kernel/device/chario.c: Include "device_reply.h" rather than
	<device/device_reply.h>.

Thu Mar 28 17:59:36 1996  Linus Kamb  <kamb@cs.utah.edu>

	* kernel/ipc/fipc.c:

		changed fipc_send() to take a fipc_endpoint_t structure
 		which has the destination hardware address and destination
 		port, instead of the two integer arguments used before.

		changed fipc_recv() to also take a fipc_endpoint_t
 		parameter that returns the senders hardware address.
  		(Their is no concept of a sending fipc port.)

		Also added some spl stuff to avoid a possible race
 		condition, and generally cleaned it up.

	* include/mach/syscall_sw.h: changed the argument #'s for fipc calls.

	* kernel/kern/syscall_sw.c: changed the argument #'s for fipc calls.

	* kernel/device/device_init.c: Changed call to fipc_thread() 
		to call to fipc_init().

Mon Mar 25 01:39:45 1996  steve clawson  <sclawson@marker.cs.utah.edu>

	* changes for VM_PROT_NOTIFY added for Godmar Back
	(gback@cs.utah.edu):
	
	* include/mach/kern_return.h: Added KERN_WRITE_PROTECTION_FAILURE
	return value.

	* include/mach/vm_prot.h: Added VM_PROT_NOTIFY.

	* kernel/vm/vm_map.c (vm_map_protect): or in VM_PROT_NOTIFY
	when we check the new protection against max protection (should
	always be able to set the NOTIFY bit, ).

	* kernel/vm/vm_map.c (vm_map_lookup): If VM_PROT_NOTIFY is set and
	we get a write protection violation, return
	KERN_WRITE_PROTECTION_FAILURE.
	
	* kernel/vm/vm_user.c (vm_protect): Make sure that we accept
	VM_PROT_NOTIFY (since it's not in VM_PROT_ALL).

Sun Mar 24 13:17:45 1996  Shantanu Goel  <goel@toner.cs.utah.edu>

	* kernel/device/dev_hdr.h: Following changes #ifdef'ed for i386.

	(device): Renamed to mach_device.  All users changed.
	(device_t): Renamed to mach_device_t.  All users changed.

	* kernel/device/dev_lookup.c: Following changes #ifdef'ed for i386.
	(dev_port_enter): Initialize emulation ops and data.
	(convert_device_to_port): Use emulation ops.
	(device_reference): Renamed to mach_device_reference.

	 ds_device_set_status, ds_device_get_status, ds_device_set_filter,
	 ds_device_map, ds_device_write_trap, ds_device_writev_trap):
	Declaration made static.  Dropped "ds_" prefix.  Interface changed.
	(ds_notify): Deleted.
	(ds_nosenders): Declaration made static.
	(io_done_thread_continue): (free_skbuffs): Use it.
	(mach_device_emulation_ops): New variable.

Mon Mar  4 10:39:03 MST 1996 Linus Kamb  (kamb@cs.utah.edu)

	* Checked in FIPC code:

	* Added kernel/ipc/fipc.[ch]
		fipc_send(int a0, int a1, char *buf, int buf_len);
			a0 and a1 together contain the 6 byte ethernet
			address of the receiving machine, and the 16 bit
			unsigned "fipc_port".
	
		fipc_recv(unsigned short fipc_port, char *buf, int *buf_len);
			Returns as much as buf_len bytes to the user's buf from
			port fipc_port.  Will block if there is no available
			message on the fipc port.  Buf_len is an IN/OUT
			parameter, giving the size of the user's buffer,
			and returning the actual number of bytes in the
			message.
	
	* Changed kernel/device/device_init.c
		starts the fipc_thread, which does necessary initialization.

	* Changed kernel/device/net_io.c
		added net_fwrite() which is very similar to net_write(), but
		is called by nefoutput() (if_ne.c) which is the path for
		fipc_send calls.

	* Changed kernel/kern/syscall_sw.c
		adding -96 and -97 for FIPC traps

	* Changed include/mach/syscall_sw.h
		adding kernel_trap() delcarations for fipc_send and fipc_recv

Tue Feb 13 22:34:27 1996  Kevin T. Van Maren  <vanmaren@fast.cs.utah.edu>

	* More diskslice changes are integrated:

	* kernel/scsi/disk_label.c: Updated this file I added last time.
	  Full support for dos partitions and BSD disklabels.  No longer
	  uses a disklabel structure for partition information encoding.
,
	* kernel/scsi/pc_scsi_label.c: No code changes

	* kernel/scsi/rz.h: rzpartition() definition changed for slices

	* kernel/scsi/rz_disk.c: Modified to use the array of partitions
	  and the common partitioning code.  Disklabels are still there
	  but are fairly meaningless to the kernel, and incorrect in any
	  event.

	* kernel/scsi/rz_disk_bbr.c: Uses new partitioning. NOT TESTED.

	* kernel/scsi/rz_labels.h: Added diskpart structure.  Also added
	  #defines for partition types in this structure.

	* kernel/scsi/scsi_defs.h: MAX_SCSI_PARTS defined

	* kernel/device/dev_name.c: Now converts a block device string to
	  the correct slice+partition fields for the partition code.

Thu Feb 8 00:27:33 MST 1996  Bryan Ford <baford@cs.utah.edu>

	Merged in changes from UK02p20 to end of UK02-freeze branch,
	and terminated the last remnant of the UK02-freeze branch.

	Fri Feb  2 17:03:38 1996  steve clawson  <sclawson@marker.cs.utah.edu>

		* kernel/ipc/ipc_notify.c: added ipc_notify_init_msg_accepted
		  call to ipc_notify_init().

	Wed Jan 17 17:04:24 1996  Bart Robinson  <lomew@fast.cs.utah.edu>

		* Serial console working for real.

		* kernel/device/cons.c, cons.h: added.  These are the same as in
		  mach4-parisc/kernel/hpdev but changed slightly to make cninit
		  re-entrant.  They can and should be used for the PA too.

		* kernel/util/console.c, console_buf.c, console_list.h: removed.
		  The console is handled differently now.

	Wed Jan 17 13:51:46 1996  Kevin Van Maren  <vanmaren.cs.utah.edu>

		* Unified the partition code for IDE & SCSI device drivers

		* kernel/scsi/disklabel.c: new file
		* kernel/scsi/rz_labels.c: deleted
		* kerenl/scsi/pc_label.c: deleted

		* kernel/scsi/rz_labels.h: Added more partition ID types. Also
		  added the prefix scsi_ to structs.

		* kernel/scsi/pc_scsi_label.c: removed grab_bob_label(),
		  default_label is now scsi_default_label.

		* kernel/scsi/rz_disk.c: Replaced scsi-specific partition code 
		  with code that calls the unified partition code.

Thu Jan 11 20:06:33 MST 1996  Bryan Ford <baford@cs.utah.edu>

	Added remote debugging support to MOSS;
	fixed a number of bugs.

Mon Oct 30 09:21:10 MST 1995  Bryan Ford <baford@cs.utah.edu>

	Merged in changes from UK02p15 to UK02p20:

	Mon Oct 23 11:03:10 1995  steve clawson  <sclawson@marker.cs.utah.edu>

		* bootstrap/bootstrap.c: Added back code to ask for a root
		device (the '-a' switch from the command line).  Added
		`translate_root' function that converts from Linux device
		names to Mach ones.

	Sun Oct 22 18:36:49 1995  Bryan Ford <baford@cs.utah.edu>

		* Integrated Steve's and Bart's changes from the UK02p16-work
		  branch.

		* bootstrap: use exec_load() to find startup's symbol table,
		  instead of trying to hand-interpret the a.out header.

		* bootstrap: no longer try to load emulator symbols; that's
		  Lites' job.

		* bootstrap: if user types in a new server directory name,
		  use the new device name as the root device as well.

		* include/mach/sa/sys/reboot.h: added BSD flag definitions.

		* mach4/kernel/ddb/db_aout.c: got rid of ddb_init();
		  instead just call aout_db_sym_init() directly from model_dep.c.

		* mach4/kernel/kern/bootstrap.c: Use MultiBoot kernel command
		  line to find root device and flags, instead of old kludgy
		  boothowto and bootdev values.

	Fri Oct 13 16:47:52 1995  steve clawson  <sclawson@marker.cs.utah.edu>

		* include/mach/multiboot.h: Added entries for symbol table
		  information and for boothowto and bootdev into the boot_info 
		  structure.

		* include/mach/exec/exec.h: Cleaned up text (>80 columns).
		* include/mach/exec/a.out.h: Added some macros from FreeBSD.

		* kernel/ddb/db_aout.c: Enabled code to load kernel symbol
		  table.

	Thu Sep 28 16:57:07 1995  steve clawson  <sclawson@marker.cs.utah.edu>

		* kernel/scsi/adapters/scsi_aha15.h: Added #defines for the
		  1542CF. 
		
		* kernel/scsi/adapters/scsi_aha15_hdw.c: Added support for the
		  1542CF.  #defined db_printf to just be printf.
		
		* kernel/scsi/adapters/scsi_aha17_hdw.c: #defined db_printf to
		  just be printf.

	Mon Jun 26 13:51:42 MDT 1995  Wolfram Stering <wolfi@cosy.sbg.ac.at>

		* kernel/scsi/*label*: fixed to support Linux-style
		  partitioning.

	Fri May 19 11:17:13 MDT 1995  Bryan Ford <baford@cs.utah.edu>

		* Released UK02p17, as a private snapshot for goel.

	Tue May 16 01:45:22 1995  Shantanu Goel  <goel@monk.mcl.cs.columbia.edu>

		* kernel/device/ds_routines.c (ds_device_set_status):
		  Pass device structure to Linux driver.
		  (ds_device_get_status): Likewise.

	Fri May  12 10:47:41 MDT 1995  Bryan Ford <baford@cs.utah.edu>

		* Released UK02p16, as an internal snapshot for rdukes

Wed Oct  4 20:04:27 MDT 1995  Bryan Ford <baford@cs.utah.edu>

	Released moss-0.80 (tag moss-0-80)

Wed Oct  4 12:05:57 MDT 1995  Bryan Ford <baford@cs.utah.edu>

	Merged in changes made for DOS extender at home:
	* better mach/sa include files
	* new list-based flexible memory allocator

Wed May  3 13:59:54 MDT 1995  Bryan Ford <baford@cs.utah.edu>

	Merged in diffs from UK02p12 to UK02p15:

	Wed May  3 10:47:41 MDT 1995  Bryan Ford <baford@cs.utah.edu>

		* Released UK02p15.
		  (UK02p14 was just an intermediate tag after adding ELF support.)

		Configuration-related changes:

		* configrules: now looks for mach4 sources in a default location
		  "next to" the machine-dependent sources if no '--with-mach4='
		  option is specified.

		ELF support changes:

		* Got rid of old ex_get_header() routine from libmach_sa.a;
		  instead provide a new library, libmach_exec.a (in libmach/exec)
		  which provides a less a.out-specific exec_load() function.

		* bootstrap/load.c, kernel/kern/bootstrap.c: use new exec_load() function.

		* Added include/mach/exec/elf.h, from OSF's server bootstrap code

		Makefile-related changes:

		* Starting to phase out GSECTIONS/MSECTIONS, because
		  that design forced all machine-dependent directories
		  to come before all machine-independent directories,
		  which isn't the right behavior in all cases.
		  Now makefiles should just build SRCDIRS directly.

		* We now generate public header files and libraries in
		  $(OBJDIR)/include and $(OBJDIR)/lib before installing them.
		  Added mach4/Makerules.lib, for various library targets to use.

		* mach4/Makerules: sort all object files at once, so that
		  .c files can override .S files and such.

		* Split out common part of mach4-i386/Makefile.in and
		  mach4-parisc/Makefile.in, and put them in mach4/Makerules.top.

		Miscellaneous changes:

		* (fjl) Various additions and fixes to the HTML pages.

		* kernel/scsi: merged in MK83a changes, including new aha17 (eaha) driver.

		* gensym.awk: 'size' command can now take an optional fourth parameter
		  indicating the name of the symbol to declare.

		* Moved errorlib.h to the public include/mach directory.

		* include/mach/machine/vm_param.h: 

		* include/mach/sa: Added some common POSIX errno's and other useful stuff.

		* libmach/standalone: Moved generic C-library stuff to libmach/c.

		* libmach/c/stdio: created, containing extremely simple high-level file I/O
		  functions that do no buffering, instead going straight to the low-level
		  Unix-like file I/O routines.

	Fri Apr  7 17:43:22 MDT 1995  Bryan Ford <baford@cs.utah.edu>

		* Released UK02p13.

Fri Apr  7 13:08:16 MDT 1995  Bryan Ford <baford@cs.utah.edu>

	Merged in diffs from UK02p9 to UK02p12:

	Mon Apr  3 19:55:41 MDT 1995  Bryan Ford <baford@cs.utah.edu>

		* Released UK02p11.
		  Too many changes to describe concisely,
		  almost all affecting only the boot mechanism for now.
		  Also, integrated the kernel/util, kernel/pc, kernel/dos code
		  from my DOS extender project at home.

	Mon Feb 27 16:32:59 MST 1995  Bryan Ford <baford@cs.utah.edu>

		* Released UK02p10 as a non-functional snapshot

Fri Feb 10 13:25:54 MST 1995  Bryan Ford <baford@cs.utah.edu>

	Merged in diffs from UK02p7 to UK02p9:

	Thu Jan 26 19:37:04 1995  steve clawson  <sclawson@fast.cs.utah.edu>

		* kernel/scsi/adapters/scsi_aha15_hdw.c:

		  Merged in MK83-MK83a changes.

		  Added code to recognize 1542CF controllers. 
		  (changes marked with a + imported from netbsd).
		
		  aha_probe(): 
		    added 1542CF case in the id switch.
		    +added code to unlock the mailbox interface on the C/CF's. 
		    +added code to set DMA on/off times
		    moved initialization around a bit:
		      commented out the code to call aha_init_1().
		      changed the call to aha_init_2() into aha_init().
		  
		* kernel/scsi/adapters/scsi_aha15.h:

		  Added AHA_BID_1542CF, AHA_EXT_BIOS and AHA_MBX_ENABLE defines.
		  Added struct aha_extbios.	    

		* bootstrap/fs.h:
		  Added fs_state field to struct fs.  (fix suggested by Remy Card)


	Tue Jan 17 15:55:01 MST 1995  Bryan Ford <baford@cs.utah.edu>

		* Released UK02p8

	03-Dec-94 Johannes Helander (jvh) at Helsinki University of Technology

		* bootstrap/ffs_file_io.c: 

		  Added support for 4.4 BSD fastlinks.  The change breaks 4.3
		  slowlinks of length four or less.

		  Interpret 4.4 BSD directory entries correctly also on little
		  endian machines.

	12 Jan 1995 17:52:44 -0500  Shantanu Goel <goel@cs.columbia.edu>

		* vm/vm_map.c: Incorporated the device_write bug fix from MK83a.

	09-Dec-94  Ian Dall (dall@hfrd.dsto.gov.au)

		* Fixed char_write_done to use ds_device_write_reply_inband when
		  appropriate.

	16-May-94  Ian Dall (idall@eleceng.adelaide.edu.au) at University of Adelaide

		* Increase tty_outq_size to 2048. *Must* be greater than largest
		  tthiwat entry or bad things happen.

	Wed Dec  7 11:43:02 MST 1994  Roland McGrath (roland@gnu.ai.mit.edu)

		* Fix to bootstrap code to interpret BSD 4.4 FFS filesystems.

Fri Nov 25 13:56:32 MST 1994  Bryan Ford  (baford@cs.utah.edu)

	Merged in diffs from UK02p6 to UK02p7:

	* GNU make should now no longer mistakenly delete any more
	  intermediate files the first time around.

	* 'make configure' should now work without producing bogus
	  error messages.  (Hint: don't put any bogus 'AC_*' text
	  strings in input files to autoconf, even if they're
	  in comments!)

	* Don't install 'Makefile.in' into the public include directory.

	* mig/Makerules (parser.o): 
	  Added explicit dependencies to protect files that were
	  automatically deleted by GNU make after the first compilation on
	  an empty object tree.  These were deleted because GNU make
	  decided that they were intermediary files.  However, because
	  they are listed in the automatically generated dependency file,
	  GNU make realizes that it must regenerate them on a subsequent
	  "make" pass.  Since they have explicit dependencies (in the
	  "depend" file) on that subsequent pass, GNU make does not delete
	  them.

Tue Nov  1 19:12:55 1994  Jeff Law  (law@snake.cs.utah.edu)

	* kernel/kern/{processor.h, task.h, thread.h}: Enclose full
	prototypes inside #if KERNEL (for "klg" files where foo_t
	is typically mapped to mach_port_t, which causes decl and defn
	not to match).

	* Merge in machine-independent kernel changes from MK83-MK83a.
	Detailed change entries in CHANGES.MK83a.log.  Effected files:

	* include/device/bpf.h: MK83a Changes.
	* include/mach/{exe, mach4, mach_types}.defs: Likewise.
	* include/mach/{host_info, pc_sample, processor_info}.h: Likewise.
	* include/mach/vm_statistics.h: Likewise.
	* kernel/chips/{audio.h, busses.h}: Likewise.
	* kernel/device/{chario.c, conf.h, net_io.c}: Likewise.
	* kernel/kern/{exception.c, host.c, mach_clock.c}: Likewise.
	* kernel/kern/{host.c mach_clock.c pc_sample.c}: Likewise.
	* kernel/kern/{processor.h, strings.c, task.c, task.h}: Likewise.
	* kernel/kern/{thread.c, thread.h}: Likewise.
	* kernel/scsi/rz_labels.c: Likewise.
	* kernel/scsi/adapters/scsi_aha15_hdw.c: Likewise.
	* kernel/vm/{vm_fault, vm_map, vm_resident}: Likewise.

	* kernel/bogus/eaha.h: New file for MK83a support.
	* kernel/kern/pc_sample.h: Likewise.
	* kernel/scsi/adapters/scsi_aha17_hdw.c: Likewise.

Sat Oct 22 14:56:33 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* Got rid of various rinky-dink C library routines
	  that were duplicated in both the kernel and libmach.
	  In the system-independent source tree, this just
	  means kern/sscanf.c so far, but I've got my eye
	  on printf.c as well.  In the i386-specific tree
	  it includes all kinds of little things such as bcopy.

Wed Oct 19 12:58:13 1994  Jeff Law  (law@snake.cs.utah.edu)

	* kernel/kern/mach.srv: Use immediate forms of act_get_state and
	act_set_state for thread_{get,set}_state.

Thu Oct 13 09:50:24 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* include/mach/sys_*.h: moved to include/mach/sa/sys/*.h.
	  Also added some other C-library-like files in there
	  for the benefit of standalone programs as well as my
	  Mach-on-DOS ("MOSS") C library.

	* Makerules: For all programs compiled on the target machine
	  (actually host machine in proper terminology),
	  add include/mach/sa to the include path.

	* Makefiles: minor cleanups, added some .PRECIOUS rules
	  to reduce the number of files gratuitously recompiled
	  the second time around.

	* libmach/unixoid: Cleaned out.  We no longer need the
	  unixoid version of libmach at all, because neither
	  the Hurd nor Lites need it (or ever will).  Good riddance.
	  We might start generating a 'libmach.a' again soon,
	  but it will contain only the "pure" Mach parts -
	  nothing related to Unix or C libraries.

	* libmach/standalone/printf.c: Broke into multiple files
	  and added various tidbits of functionality.

Fri Sep 30 01:43:16 1994  Jeff Law  (law@snake.cs.utah.edu)

	* kernel/bogus/bogus.c: New file.

Mon Sep 26 12:58:57 1994  Jeff Law  (law@snake.cs.utah.edu)

	* kernel/kern/processor.c (pset_init): Nuke debugging printf.

	* kernel/kern/thread.c (thread_create_in): Grab a reference to the
	processor set for the new thread.

Fri Sep  9 00:00:53 1994  Jeff Law  (law@snake.cs.utah.edu)

	* kernel/device/ds_routines.c (io_done_thread): Nuke call to
	stack_privilege.

Thu Sep  8 11:37:03 1994  Jeff Law  (law@snake.cs.utah.edu)

	* kernel/kern/act.c (act_set_state, act_get_state): Use natural_t
	to match prototype.

	* kernel/kern/zalloc.c: lock_zone has been renames to zone_lock,
	likewise for unlock_zone.
	
	* kernel/bogus/mach_pcsample.h: Disable for now.
	* kernel/bogus/xpr_debug.h: Likewise.

	* include/mach/rpc.h: Add c-signature stuff.

	* kernel/device/chario.c (ttstart): New function.
	(ttrstrt): Use it.

	* include/mach/mach4.defs: Wrap PC sampling stuff inside
	an appropriate #ifdef.

Wed Aug 31 10:59:51 1994  Jeff Law  (law@fast.cs.utah.edu)

	* kernel/ipc/ipc_notify.c: Use MACH_MSG_TYPE_INTEGER_32 rather
	than MACH_MSG_TYPE_INTEGER_T.

	* kernel/kern/ipc_sched.c: Don't include thread_swap.h

	* kernel/kern/sched_prim.c (thread_wakeup_prim): "event" should
	be an event_t.  Cast argument to wait_hash to an int.
	(various): Chagne thread->runq to thread->shuttle.runq.

	* kernel/device/net_io.c: Don't typedef u_long here.

	* kernel/kern/ipc_kobject.c: Include mach_machine_routines.h

	* kernel/device/ds_routines: Include current.h for current_thread.

	* include/mach/sys_types.h: Put u_long back.

Tue Aug 30 13:45:05 MDT 1994

	* Makefiles: Don't use CFLAGS etc. to build variables in;
	that way the user can specify them on the `make' line
	and still get sensible results.
	Also, named some variables HOST_xxx and TARGET_xxx
	to better support cross-compilation.

Fri Aug 26 12:06:35 1994  Jeff Law  (law@fast.cs.utah.edu)

	* include/mach/mach_port.defs: Use thread_t, not act_t.

Mon Aug 1 18:15:00 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* Got most of the migrating threads changes merged in

Tue Oct 25 12:32:28 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* Released UK02p6.

	* Moved exec header interpretation stuff from the bootstrap code
	  into libmach so the kernel could also use it when initializing
	  the bootstrap program itself.

Sat Oct 22 15:44:42 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* Moved cthreads.h from the top-level public include directory
	  into the mach/ include subtree.  Higher-level OS personalities
	  can create their own cthreads.h, or just make a stub
	  that cross-includes mach/cthreads.h if they want to use
	  the "standard" implementation.

Mon Oct 17 10:54:38 ??? 1994  Csizmazia Balazs  (csb@ullman.elte.hu)

	* Added MINIX filesystem support to the bootstrap loader.

Sat Oct 15 17:22:01 MDT 1994  Bryan Ford (baford@cs.utah.edu)

	* Temporary kludge: added servers/ include directory
	  containing libmachid and libnetname headers;
	  added corresponding library code to libmach.
	  This is so we can compile Lites against Mach4
	  without having to create a full new USER package yet.

	* Changed ifdef's of KERNEL to MACH_KERNEL
	  in the public header files.
	  (Really should get rid of them entirely.)

Fri Sep 16 11:33:44 MDT 1994  Bryan Ford (baford@cs.utah.edu)

	* Released UK02p5.

	* Added copyrights to the makefiles.

Fri Sep  9 10:44:49 MDT 1994 Bryan Ford (baford@cs.utah.edu)

	* configure.in: if user specifies --enable-debug,
	  add -DDEBUG to the compiler flags.

Tue Sep  6 09:58:49 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* Added blank .SUFFIXES line
	  to eliminate the requirement of using `make -r'.
	  (Things still go faster with `-r' though.)

Mon Sep  5 22:44:00 1994  Patrick Doyle  (wpd@peanutbutter)

	* README (DIRECTORY STRUCTURE): Added a distillation of a
	  discussion with Bryan regarding organization of and differences
	  between the two libraries produced by the distribution.  (Also
	  cleaned up references to libmach_ux.a when I stumbled across
	  them in the source).

Mon Sep  5 12:16:30 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* Full cross compilation support

	* Cleaned up all install rules
	  so they will no longer gratuitously reinstall things.

Sun Sep  4 11:33:03 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* As suggested by Roland McGrath,
	  changed the genassym mechanism to cross-compile better,
	  by compiling to assembly language source
	  instead of an executable program.

	  Also refined and extended this technique
	  to make it more convenient,
	  and to allow MIG to use it too.

Sun Sep  4 08:10:05 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* Makefiles: better cross-compilation support.

Sat Sep  3 15:14:36 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* bootstrap/*: got FFS support back in;
	  now both ext2 and FFS are supported at the same time
	  (although in a horrendously kludgy way).

Wed Jul 20 14:00:45 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* include/mach/mig_support.h: Got rid of cross-includes
	  of some old bogus header files.

	* Released UK02


Mon Jul 18 18:28:00 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	Integrated microkernel changes needed by LITES,
	from Johannes Helander (jvh) and Tero Kivinen (kivinen) @cs.hut.fi:

	* (jvh) include/device/device_reply.defs: added SEQNOS support.

	* (jvh) include/mach/error.h: Surrounded typedefs with ifndef ASSEMBLER.

	* (jvh) mig, libmach: mig_dealloc_reply_port() now takes an argument,
	  which is ignored in the default libmach implementation of this function,
	  but may be needed for custom reply port allocators.
	  MIG stubs now pass the reply port to be deallocated.

	* (jvh) mig, libmach: new function mig_put_reply_port(),
	  which does nothing in the default libmach implementation.
	  MIG stubs call this function when done with a reply port,
	  if it wasn't deallocated with mig_dealloc_reply_port().

	* (jvh) mig/mig.sh: added -migcom flag to specify the location of migcom.

	* (jvh) libmach/err_kern.sub: added new errno strings for 4.4BSD and Lite.

	* (???) libthreads: added wait_type to cproc structure
	  keeping track of what type of event is being waited for.

	* (???) libthreads: added a holder field to mutex structure
	  keeping track of who's holding a mutex, for debugging.

	* (kivinen) libthreads: Renamed cthread_t->catch to cthread_t->catch_exit,
	  because catch is a reserved word in C++.

	* (jvh) libthreads: Added CONDITION_NAMED_INITIALIZER and MUTEX_NAMED_INITIALIZER
	  macros.  They take one argument: a name string.


Fri Jul 15 11:46:19 MDT 1994  Bryan Ford  (baford@cs.utah.edu)

	* kern/bootstrap.c: gutted and rewrote
	  to get the boot image from the bmod mechanism.
	  Needs to be gutted still more.
