9639d2bb98 modify udv_attach() and its caller (uvm_mmap()) so that it's passed the 
offset and size of the requested region to be mapped, so that the
udv_attach() can use the device d_mmap() entry to check mappability
of the requested region.

025ae6bd64 remove unused share map code from UVM: 
- update calls to uvm_unmap_remove/uvm_unmap (mainonly boolean arg
	has been removed)
 - replace UVM_ET_ISMAP checks with UVM_ET_ISSUBMAP checks

8219f068e2 Declare silent success on madvise(). As an advisory call, it is harmless 
to pretend success even though it's not supported, and some emulations
rely on its success.

6b11eea5b2 reject attempts to map an immutable or append-only file, shared with 
write protection.  this stops data corruption where it was possible
to change the in-memory copy of an append-only file (but not the on-disk
copy).  this is documented in NetBSD security advisory 1998-003.  thanks
to darrenr, lukem, cgd, mycroft and mrg for this.

39b4c2fece mmap() default MAP_SHARED/MAP_PRIVATE is `DEBUG'', not `DIAGNOSTIC'' 1998-04-01 21:43:52 +00:00

6618749e5a Per XPG, if the file descriptor argument to mmap() refers to a file whose 
type is not supported (neither VREG nor VCHR, or not a vnode at all), fail
with ENODEV instead of EINVAL.

24e6e6a0e7 Convert MAP_PRIVATE device mappings to MAP_SHARED on *all* platforms, not just 
the SPARC.
Remove the #ifdef COMPAT_13 for automatically adding a sharing type, since the
interface is *supposed* to support this.
Also modify the DIAGNOSTIC messages here a bit.

f2caacc717 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the UVM kernel code portion.


this will be KNF'd shortly.  :-)
