jail(8) security.jail.chflags_allowed sysctl,
zs driver removed,
ng_ipfw(4) added,
ips(4) crash dump support,
getaddrinfo(3) DNS query order changed,
powerd(8) added, and
RFC derived manual pages replaced.
Update release notes:
acpi_throttle and acpi_perf merged into acpi and
can be disabled via device hints, and
some rewording due to zs driver removal in the entry which
explains uart(4) has been enabled by default on FreeBSD/sparc64.
a serial console anyway because input-device is set to keyboard and
output-device is set to screen but no keyboard is plugged in don't
assume that a device node for the input-device alias exists. While
this is true for RS232 keyboards (the node of the SCC and UART
respectively which controls the keyboard doesn't disappear when no
keyboard is plugged in) this assumption breaks for USB keyboards.
It's most likely also not true for PS/2 keyboards but OFW doesn't
reliably switch to a serial console when the potential keyboard is
a PS/2 one which isn't plugged in so this couldn't be verified
properly.

accept filter option during connect, and the two socket mutex regions
(transition to connected, perform accept filter) are combined.
from uipc_socket.c to uipc_accf.c in do_getopt_accept_filter(), so that it
now matches do_setopt_accept_filter(). Slightly reformulate the logic to
match the optimistic allocation of storage for the argument in advance,
and slightly expand the coverage of the socket lock.
OR the physical address with alpha_XXX_dmamap_or to get the DMA address,
like the name of the variable suggests. However, while we were doing
this correctly in the alpha_XXX_dmamap() macro, the busdma code added
the variable to the physical address instead of or'ing it. Fortunately
and if my math is not entirely wrong, you would need more than 128GB of
RAM and a device able to do DMA in 64bits to experience the bug.

long filename. Each substring is indexed by the windows ID, a
sequential one-based value. The previous code was extremely slow,
doing a malloc/strcpy/free for each substring.
This code optimizes these routines with this in mind, using the ID
to index into a single array and concatenating each WIN_CHARS chunk
at once. (The last chunk is variable-length.)
This code has been tested as working on an FS with difficult filename
sizes (255, 13, 26, etc.) It gives a 77.1% decrease in profiled
time (total across all functions) and a 73.7% decrease in wall time.
Test was "ls -laR > /dev/null".
Per-function time savings:
mbnambuf_init: -90.7%
mbnambuf_write: -18.7%
mbnambuf_flush: -67.1%

socket lock around knlist_init(), so don't.
Hard code the setting of the socket reference count to 1 rather than
using soref() to avoid asserting the socket lock, since we've not yet
exposed the socket to other threads.
This removes two mutex operations from each socket allocation.
