(not interface addresses) to see if a given address is on-link.
- skip offlink prefixes in neighbor determination in nd6_is_addr_neighbor.
- in nd6_is_addr_neighbor, regarded every address as on-link when the
default router list is empty. otherwise, we'd not be able make a neighbor
cache for the address.
this algorithm is applied to hosts only.
- in nd6_is_addr_neighbor, check if the default interface is equal to
the interface in question in addition to check if the default router
list is empty.

Serialize access to the SATA channels, the chip messes up if
both channels are used at the same time.
The SiI3112 hereby takes the price as the most crappy SATA chip in
existance by a significant amount.
My advise to our userbase is to avoid this chip like the plague...
Setup decent transfer mode defaults as some BIOS's seem to put in
things that it *knows* doesn't work.
(Note to BIOS writers: stop doing that nonsense, we will get things
working with your crappy HW anyways, and then recommend users to buy
someone else's products that "just works", thankyou.. )
Limit the device transfer mode to ATA100/UDMA5 on generic SATA.
Since we dont know if the user is using a pure SATA device or an
old PATA drive with a SATA converter dongle, we need to limit the
speed used here to cover up the problems with Marvell ATA-SATA bridges
used in lots of SATA products.
This workaround is enabled for all detectable SATA controllers as they
seem to have semilar problems here. One notable exception is all the
Promise pdc2037x chips which just always work (cudos to Promise!).

Instead, allow the mapping to persist, but add the sf_buf to a free list.
If a later sendfile(2) or zero-copy send resends the same physical page,
perhaps with the same or different contents, then the mapping overhead is
avoided and the sf_buf is simply removed from the free list.
In other words, the i386 sf_buf implementation now behaves as a cache of
virtual-to-physical translations using an LRU replacement policy on
inactive sf_bufs. This is similar in concept to a part of
http://www.cs.princeton.edu/~yruan/debox/ patch, but much simpler in
implementation. Note: none of this is required on alpha, amd64, or ia64.
They now use their direct virtual-to-physical mapping to avoid any
emphemeral mapping overheads in their sf_buf implementations.
an int constant to a long constant. This change improves consistency
in the following two ways:
1. The first 8 arguments are always passed in registers on ia64, which
by virtue of the generated code implicitly widens ints to longs and
allows the use of an 32-bit integral type for 64-bit arguments.
Subsequent arguments are passed onto the memory stack, which does
not exhibit the same behaviour and consequently do not allow this.
In practice this means that variadic functions taking pointers
and given NULL (without cast) work as long as the NULL is passed
in one of the first 8 arguments. A SIGSEGV is more likely the
result if such would be done for stack-based arguments. This is
due to the fact that the upper 4 bytes remain undefined.
2. All 64-bit platforms that FreeBSD supports, with the obvious
exception of ia64, allow 32-bit integral types (specifically NULL)
when 64-bit pointers are expected in variadic functions by way of
how the compiler generates code. As such, code that works correctly
(whether rightfully so or not) on any platform other than ia64, may
fail on ia64.
To more easily allow tweaking of the definition of NULL, this commit
removes the 12 definitions in the various headers and puts it in a
new header that can be included whenever NULL is to be made visible.
This commit fixes GNOME, emacs, xemacs and a whole bunch of ports
that I don't particularly care about at this time...
flags. We now create asynchronous contexts or syscall contexts only.
Syscall contexts differ from the minimal ABI dictated contexts by
having the scratch registers saved and restored because that's where
we keep the syscall arguments and syscall return values.
Since this change affects KSE, have it use kse_switchin(2) for the
"new" syscall context.
functions less noisy: We printf if a new function took longer than
the previous record holder, or of the previous record holder took
more than twice as long as the current record.
to have the kernel switch to a new thread, instead of doing it in
userland. It is in fact needed on ia64 where syscall restarts do not
return to userland first. It's completely handled inside the kernel.
As such, any context created by the kernel as part of an upcall and
caused by some syscall needs to be restored by the kernel.
Be sure to shift (long)1 << 33 and higher, not (int)1. Otherwise bad
things happen(TM). This is why beast.freebsd.org paniced with ULE.

system super block after fsck has repaired the file system. The value of
fs_ronly was getting overwritten, which caused ffs_update() to attempt to
update inode timestamps even though the file system was still mounted
read-only.
This fixes the "giving up on N buffers" error that is triggered by running
fsck on the root file system and then rebooting without mounting the file
system read-write.

a long time: lmc The LAN Media Corp PCI WAN driver based on tulip.
This driver hasn't compiled for 3 years since the PCI compat shims
were removed, and Lan Media appears to have gone out of business.
These cards appear to be rare (a recent search of ebay had no hits).
Should someone wish to revive this driver, submitting patches to make
it compile plus a testing report will bring it back.
