the non-reserved bits of dr7.
During context restore, load dr7 in such a way as to not
disturb reserved bits.
machdep.c: Don't explicitly disallow the setting of the reserved bits
in dr7 since we now keep from setting them when we load dr7
from the PCB.
This allows one to write back the dr7 value obtained from
the system without triggering an EINVAL (one of the
reserved bits always seems to be set after taking a trace
trap).

If bus_dma will give us addresses > 32 bits, setup our dma tag
to accept up to 39bit addresses.
aic7770.c:
Update the softc directly rather than use an intermediate
"probe_config" structure.
aic7xxx.c:
Complete core work to support 39bit addresses for bulk data
dma operations. Controller data structures still must reside
under the 4GB boundary to reduce code/data size in the sequencer
and related data structures. This has been tested under Linux
IA64 and will be tested on IA64 for FreeBSD as soon as our port
can run there.
Add bus dmamap synchronization calls around manipulation of
all controller/kernel shared host data structures.
Implement data pointer reinitialation for a second data phase
in a single connection in the kernel rather than bloat the
sequencer. This is an extremely rare operation (does it ever
happen?) and the sequencer implementation was flawed for some
of the newest chips.
Don't ever allow our target role to initiate a PPR. This
is forbidden by the SCSI spec.
Add a few missing endian conversions in the ignore wide pointers
code. The core has been tested on the PPC under Linux and should
work for FreeBSD PPC. As soon as I can test the OSM layer for
FreeBSD PPC, I will.
Move some of ahc_softc_init() into ahc_alloc() now that the
probe_config structure is gone.
Add a 4GB boundary condition on all of our dma tags. 32bit
DAC under PCI only works on a single 4GB "page". Although
we can cross 4GB on a true 64bit bus, the card won't always
be installed in one and we can save code space and cost in
implementing high address support by assuming the high DWORD
address will never change.
Add diagnostics to ahc_search_qinfifo().
Correct a target mode issue with bus resets. To avoid an
interrupt storm from a malicious third party holding the
reset line, the sequencer would defer re-enabling the reset
interrupt until either a select-out or select-in. Unfortunately,
the select-in enable bit is cleared by a bus reset, so a second
reset will render the card deaf to an initiator's attempts to
contact it. We now re-enable bus reset interrupts immediately
if the target role is enabled.
aic7xxx.h:
Remove struct ahc_probe_config.
SCB's now contain a pointer to the sg_map_node so we can perfrom
bus dma sync operations on the SG list prior to queuing a command.
aic7xxx.reg:
Register the Perforce ID for this file with the VERSION keyword
so it is printed in generated files.
Add the DSCOMMAND1 register which is used to access the high
DWORD of address bits.
Add the data pointer reinitialize sequencer interrupt code.
aic7xxx.seq:
Register the Perforce ID for this file with the VERSION keyword
so it is printed in generated files.
Remove code to re-enable the bus reset interrupt after a select-in.
In target mode we cannot defer this operation as ENSELI is cleared
by a bus reset.
Complete 39bit support.
Generate a sequencer inteerrupt rather than handle the data
pointers re-initialitation in the sequencer.
Inline the "seen identify" assertion to save a few cycles.
Short circuit the update of our residual data if we have
fully completed a transfer. The residual is correct from
our last S/G load operation.
Short circuit full SDPTR processing if the residual is 0.
Just mark the transfer as complete.
aic7xxx_93cx6.c:
Synchronize perforce IDs.
aic7xxx_freebsd.c:
Complete untested 39bit support.
Add missing endia conversions.
Clear our residuals prior to starting a command. The
update residual code in the core only sets the residual
if there is one.
aic7xxx_freebsd.h:
Modeify ahc_dmamap_sync() macros to take an offset and a length.
This is how sync operations are performed in NetBSD, and we should
update our bus dma implementation to match.
aic7xxx_inline.h:
Add data structure synchronization helper functions.
Fix a bug in ahc_intr() where we would not clear our unsolicited
interrupt counter after running our PCI interrupt handler. This
may have been the cause of the spurious PCI interrupt messages.
aic7xxx_pci.c:
Adjust for loss of probe_config structure.
Guard against bogus 9005 subdevice information as seen on some
IBM MB configurations.
Add 39bit address support.

e->cmd. free_entry() now does the right thing with
partially-initialized structures.
load_entry(): Don't call env_free() on e->envp throughout the routine
before jumping to eof; the free_entry() call at that label will take
care of it. The previous behavior resulted in e->envp being free'd
twice (well, the second time would usually result in a crash, but
that's besides the point); once in load_entry(), and once in
free_entry() after the former called the latter. Also note that the
check added to free_entry() (above) doesn't help, since e->envp wasn't
reset to NULL after env_free().

removing a modules directory is not all that uncommon a mistake,
and finding a file with the contents of the last module installed
is a baaad surprise at boot time..

According to RFC 1112, which deals with multicasting, an application must
specify the interface on which it wished to send a multicast packet. In the
absence of such an interface, a default is selected.
Previous behavior in ip_output.c erroneously checked for a route to the
destination multicast address, rejecting the packet if none existed.
Applications got around this with a FAQ recommending a 224.0.0.0/29 route
to loopback. This worked because the multicast code in ip_output.c discards
route information if an interface was selected.
The previous commit skips the route check in the case where a multicast packet
is being send to an application-defined interface.
The only change in behavior, if no bugs were introduced, is the lack of
rejection of a multicast packet for which no route exists sent to an
application-defined interface.

This macro was supposed to only match local IP addresses of

well. (See IP_MULTICAST_IF and IP_ADD_MEMBERSHIP socket
