modules split across several physical medias. Following is how it works:
The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.
foo.aa "Kernel floppy 1"
foo.ab "Kernel floppy 2"
foo.ac "Kernel and modules floppy"
For each file segment, the process is:
- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located
RE team is free to use this feature in the upcoming 5.0-DP1.

the release notes compare 5.0-CURRENT to 4.0-RELEASE, but in at least
one place it is beneficial to mention the last stable release of
FreeBSD (4.5-RELEASE).

the motivation for saving and restoring the map->hint in useracc() is gone.
(The same tests that motivated this change in revision 1.57 now show that
there is no performance loss from removing it.) This was really a hack and
some day we would have had to add new synchronization here on map->hint
to maintain it.
to copy the sigframe to the user's stack. Useracc() takes a non-trivial
amount of time. Eliminating it speeds up signal delivery by 15% or more.

the user mappings from the tlb due to the context numbers rolling over. The
store to the internal mmu register must be followed by a membar #Sync before
much else happens to "avoid data corruption", so we use special inlines which
both disable interrupts and ensure that the compiler will not insert extra
instructions between the two. Also, load the tte tag and check if the context
is nucleus context, rather than relying on the priviledged bit which doesn't
actually serve any purpose in our design, and check the lock bit too for
sanity.
locking flags when acquiring a vnode. The immediate purpose is
to allow polling lock requests (LK_NOWAIT) needed by soft updates
to avoid deadlock when enlisting other processes to help with
the background cleanup. For the future it will allow the use of
shared locks for read access to vnodes. This change touches a
lot of files as it affects most filesystems within the system.
It has been well tested on FFS, loopback, and CD-ROM filesystems.

pmap_qremove. pmap_kenter is not safe to use in MI code because it is not
guaranteed to flush the mapping from the tlb on all cpus. If the process
in question is preempted and migrates cpus between the call to pmap_kenter
and pmap_kremove, the original cpu will be left with stale mappings in its
tlb. This is currently not a problem for i386 because we do not use PG_G on
SMP, and thus all mappings are flushed from the tlb on context switches, not
just user mappings. This is not the case on all architectures, and if PG_G
is to be used with SMP on i386 it will be a problem. This was committed by
peter earlier as part of his fine grained tlb shootdown work for i386, which
was backed out for other reasons.
