udp_in6, and udp_ip6 to pass socket address state between udp_input(),
udp_append(), and soappendaddr_locked(). While file in the default
configuration, when running with multiple netisrs or direct ithread
dispatch, this can result in races wherein user processes using
recvmsg() get back the wrong source IP/port. To correct this and
related races:
- Eliminate udp_ip6, which is believed to be generated but then never
used. Eliminate ip_2_ip6_hdr() as it is now unneeded.
- Eliminate setting, testing, and existence of 'init' status fields
for the IPv6 structures. While with multiple UDP delivery this
could lead to amortization of IPv4 -> IPv6 conversion when
delivering an IPv4 UDP packet to an IPv6 socket, it added
substantial complexity and side effects.
- Move global structures into the stack, declaring udp_in in
udp_input(), and udp_in6 in udp_append() to be used if a conversion
is required. Pass &udp_in into udp_append().
- Re-annotate comments to reflect updates.
With this change, UDP appears to operate correctly in the presence of
substantial inbound processing parallelism. This solution avoids
introducing additional synchronization, but does increase the
potential stack depth.

motherboard, in practice the changes resulted in many false positives for
heavy network loads, etc. resulting in poor performance. Also, the
motherboard referenced in the 1.109 log has other problems and simply does
not seem to work with the APIC enabled even with the changes in 1.109. The
correct fix for that board seems to be to not use the APIC at all. One
thing kept from 1.109 is that throttled interrupts are now effectively
polled on every clock tick rather than just 10 times per second.

need for most calls to vm_page_busy(). Specifically, most calls to
vm_page_busy() occur immediately prior to a call to vm_page_remove().
In such cases, the containing vm object is locked across both calls.
Consequently, the setting of the vm page's PG_BUSY flag is not even
visible to other threads that are following the synchronization
protocol.
This change (1) eliminates the calls to vm_page_busy() that
immediately precede a call to vm_page_remove() or functions, such as
vm_page_free() and vm_page_rename(), that call it and (2) relaxes the
requirement in vm_page_remove() that the vm page's PG_BUSY flag is
set. Now, the vm page's PG_BUSY flag is set only when the vm object
lock is released while the vm page is still in transition. Typically,
this is when it is undergoing I/O.
