1) dummynet_io() declaration has changed.
2) Alter packet flow inside dummynet: allow certain packets to bypass
dummynet scheduler. Benefits are:
- lower latency: if packet flow does not exceed pipe bandwidth, packets
will not be (up to tick) delayed (due to dummynet's scheduler granularity).
- lower overhead: if packet avoids dummynet scheduler it shouldn't reenter ip
stack later. Such packets can be fastforwarded.
- recursion (which can lead to kernel stack exhaution) eliminated. This fix
long existed panic, which can be triggered this way:
kldload dummynet
sysctl net.inet.ip.fw.one_pass=0
ipfw pipe 1 config bw 0
for i in `jot 30`; do ipfw add 1 pipe 1 icmp from any to any; done
ping -c 1 localhost
3) Three new sysctl nodes are added:
net.inet.ip.dummynet.io_pkt - packets passed to dummynet
net.inet.ip.dummynet.io_pkt_fast - packets avoided dummynet scheduler
net.inet.ip.dummynet.io_pkt_drop - packets dropped by dummynet
P.S. Above comments are true only for layer 3 packets. Layer 2 packet flow
is not changed yet.

Fix for the panic("vm_thread_new: kstack allocation failed") and
silent NULL pointer dereference in the i386 and sparc64 pmap_pinit()
when the kmem_alloc_nofault() failed to allocate address space. Both
functions now return error instead of panicing or dereferencing NULL.
As consequence, vmspace_exec() and vmspace_unshare() returns the errno
int. struct vmspace arg was added to vm_forkproc() to avoid dealing
with failed allocation when most of the fork1() job is already done.
The kernel stack for the thread is now set up in the thread_alloc(),
that itself may return NULL. Also, allocation of the first process
thread is performed in the fork1() to properly deal with stack
allocation failure. proc_linkup() is separated into proc_linkup()
called from fork1(), and proc_linkup0(), that is used to set up the
kernel process (was known as swapper).

The intent of the freeing the (zeroed) page in vm_page_cache() for
default object rather than cache it was to have
vm_pager_has_page(object, pindex, ...) == FALSE to imply that there is
no cached page in object at pindex. This allows to avoid explicit
checks for cached pages in vm_object_backing_scan().
For now, we need the same bandaid for the swap object, otherwise both
the vm_page_lookup() and the pager can report that there is no page at
offset, while page is stored in the cache. Also, this fixes another
instance of the KASSERT("object type is incompatible") failure in the
vm_page_cache_transfer().

Decouple the install tools from the main system as much as possible.
I.e., not only copy them to a scratch dir, but also make them use saved
copies of libraries and locale files. That gives us several benefits:
1) ABI breakages should no longer affect installworld over the live system.
2) It becomes safe to run installworld while still running the old kernel.
However, it can be reasonable to save the old /rescue before that to be
able to run the old reboot(8), as the new binaries are rather likely to
fail with the old kernel. Anyhow, it's now possible to upgrade a system
in a single reboot _reliably_.
3) With a bit of hackery around rtld(8), it becomes possible to do destructive
cross-installs, e.g., i386->amd64 over the live system.
The only shared item left between the old and new systems is rtld(8),
which cannot be run from a saved copy easily because its full
pathname is stored in the respective field of each ELF executable.
(In theory, that field could be overridden, e.g., from the environment,
but this can lead to security issues.) That's why a destructive
cross-install isn't possible w/o hackery yet.
