Change log:
2000-02-05 Johan Rydberg <johan.rydberg@netinsight.net>
* RELEASE 0.1.2.0.1.
* bootstrap/cons.c (cons_init): Support for cursor.
(cnscrollup): Clears the line at the bottom.
* RELEASE 0.1.2.0.
* src/ipc/Makefile.am (SOURCES): New file: ipc_syscall.c.
* src/ipc/ipc_portal.c (ipc_portal_receive): New function.
* src/kern/thread.h: Added ipc_msgh member; contains
pointer to message buffer (saved state).
* src/ipc/ipc_portal.c (ipc_portal_send): New function.
2000-02-03 Johan Rydberg <johan.rydberg@netinsight.net>
* src/kern/sched.c (thread_invoke): Right now when we
detect a swapped thread we associate a kernel stack with
it (and not tries to do some paging).
2000-02-02 Johan Rydberg <johan.rydberg@netinsight.net>
* src/kern/thread.c (thread_init): Now sets both priority
and sched_credit (in the template thread).
* src/vm/vm_map.c (vm_map_entry_alloc): Does not allocate
more entries if needed. This is done by the new function
vm_map_entry_alloc_check. This function is called when a
new entry is inserted into the map (and all allocation is
finished).

function.

to vm_map_enter (caused a crash in vm_fault).
(vm_map_physical): Small bug fix. Now we do the correct mapping.
* src/vm/vm_map.c (vm_map_enter, vm_map_allocate): Now returns
correct error values.
2000-01-28 Johan Rydberg <johan.rydberg@netinsight.net>

right type of data to vm_map_enter.
