such that 'ispcvt' can build. Unforunately 'ispcvt' is needed in order for
/etc/rc.d/syscons to run. This fixes the bug where I could not get my
keymap effective at boot.
turnstile_unpend(). A racing thread that does not have TDI_LOCK set may
either be running on another CPU or it may be sitting on a run queue if it
was preempted during the very small window in turnstile_wait() between
unlocking the turnstile chain lock and locking sched_lock.
case of a turnstile having no threads is just one instance of the more
general case where the thread we are examining has been partially awakened
already in that it has been removed from the turnstile's blocked list but
still has TDI_LOCK set. We detect that case by checking to see if the
thread has already had a turnstile reassigned to it.
reboot, as calling OF_exit() just hangs a mac.
FreeBSD on my G4 800Mhz mac behaves identically to OSX for halt
and reboot now.

Not all transfers between kernel and user space are byte oriented
and thus alignment safe. Especially fuword*() and suword*() are
sensitive to alignment but in general more optimal than block copies.
By catching the misalignment trap we avoid pessimizing the common
case of properly aligned memory accesses which we would do if we
were to use byte copies or adding tests for proper alignment.
Note that the expectation that the kernel produces aligned pointers
is unchanged. This change therefore relates to possible unaligned
pointers generated in userland.
versions of the firmware. It responds more slowly to commands, and we
bogusly failed them. We assume that all versions of the intersil
firmware before 1.0 are 10 times slower and will give it 10x the time
to finish.
# for 5.2 we should always just assume 5s.
(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!).
as these ioctl's aren't MD. This also means they are installed in
/usr/include/dev/bktr now. Also provide compatability wrappers for
where these headers lived in 4.x.
