Reading /dev/mem in 64 bit kernel crashes. This is because the page
used to call uiomove_fromphys() from memrw() does not have md.pv_list
initialized correctly.
The fix is to call pmap_page_init() on the page to initialize it.
separation rewrite changes. r196865 was committed to fix a scope
violation problem in the following test scenario:
box-1# ifconfig em0 inet6 2001:db8:1:: prefixlen 64 anycast
box-1# ifconfig em1 inet6 2001:db8:2::1 prefixlen 64
box-2# ifconfig re0 inet6 2001:db8:1::6 prefixlen 64
em0 and re0 are on the same link.
box-2# ping6 2001:db8:1::
PING6(56=40+8+8 bytes) 2001:db8:1::6 --> 2001:db8:1::
the ICMPv6 response should have a source address of em1, which
is 2001:db8:2::1, not the link-local address of em0.
That code is no longer necessary and breaks the IPv6-Ready logo
testing, so revert it now.

Also remove the remnants of TCP_METRICS_CWND which used the
TCP hostcache to set the initial CWND in a non-RFC compliant
way.

- A race condition could happen if two threads were using RAS at the same time
as the code didn't reset RAS_END, the RAS code could believe we were not in
a RAS, when we were in fact.
- Using signed value logic to compare addresses wasn't such a good idea.
Many thanks to Ian to investigate on these issues.

This fixes a compiler warning at WARNS=6 when including the header files
as follows:
#include <sys/types.h>
#include <netinet/in.h>
#include <netinet/ip_var.h>
#include <netinet/udp.h>
#include <netinet/udp_var.h>
To run a /31 network, participating hosts MUST drop support
for directed broadcasts, and treat the first and last addresses
on subnet as unicast. The broadcast address for the prefix
should be the link local broadcast address, INADDR_BROADCAST.
- Remove ia_net, ia_netmask, ia_netbroadcast from struct in_ifaddr.
- Remove net.inet.ip.subnetsarelocal, I bet no one need it in 2011.
- fix bug when we were not forwarding to a host which matches classful
net address. For example router having 192.168.x.y/16 network attached,
would not forward traffic to 192.168.*.0, which are legal IPs in
CIDR world.
- For compatibility, leave autoguessing of mask based on class.
