watchdog might hide the succesful arming of an earlier one. Accept that on
failing to arm any watchdog (because of non-supported timeouts) EOPNOTSUPP is
returned instead of the more appropriate EINVAL.

always 0. Previously we aligned threads on a minimum of 8-byte boundaries.
Note: This changes the uma zone to no longer cache align threads. We
really want the uma zone to do align threads to MAX(16, cache line size)
but there currently isn't a good way to express that to uma.

When submitting rx buffers and not using WC fifo, always replace the
invalid DMA address with the real one, otherwise allocation failures
could lead to the invalid DMA address being given to the NIC, and
that would cause the receive side to lockup.
with `pw lock', so that it's impossible to log into a locked account
using an alternative authentication mechanism, such as an ssh key.
This change affects only accounts locked with pw(8), i.e., having a
`*LOCKED*' prefix in their password hash field, so people still can
use a different pattern to disable password authentication only.
Mention all account management criteria in the manpage.

causing a crash.
Suppose that we have two objects, obj and backing_obj, where
backing_obj is obj's backing object. Further, suppose that
backing_obj has a reference count of two. One being the reference
held by obj and the other by a map entry. Now, suppose that the map
entry is deallocated and its reference removed by
vm_object_deallocate(). vm_object_deallocate() recognizes that the
only remaining reference is from a shadow object, obj, and calls
vm_object_collapse() on obj. vm_object_collapse() executes
if (backing_object->ref_count == 1) {
/*
* If there is exactly one reference to the backing
* object, we can collapse it into the parent.
*/
vm_object_backing_scan(object, OBSC_COLLAPSE_WAIT);
vm_object_backing_scan(OBSC_COLLAPSE_WAIT) executes
if (op & OBSC_COLLAPSE_WAIT) {
vm_object_set_flag(backing_object, OBJ_DEAD);
}
Finally, suppose that either vm_object_backing_scan() or
vm_object_collapse() sleeps releasing its locks. At this instant,
another thread executes vm_object_split(). It crashes in
vm_object_reference_locked() on the assertion that the object is not
dead. If, however, assertions are not enabled, it crashes much later,
after the object has been recycled, in vm_object_deallocate() because
the shadow count and shadow list are inconsistent.

it via pci_get_vpd_*() rather than always reading it for each device during
boot. I've left the tunable so that it can still be turned off if a device
driver causes a lockup via a query to a broken device, but devices whose
drivers do not use VPD (the vast majority) should no longer result in
lockups during boot, and most folks should not need to tweak the tunable
now.

cpufreq_pre_change is called before the change, giving each driver a chance
to revoke the change. cpufreq_post_change provides the results of the
change (success or failure). cpufreq_levels_changed gives the unit number
of the cpufreq device whose number of available levels has changed. Hook
in all the drivers I could find that needed it.
* TSC: update TSC frequency value. When the available levels change, take the
highest possible level and notify the timecounter set_cputicker() of that
freq. This gets rid of the "calcru: runtime went backwards" messages.
* identcpu: updates the sysctl hw.clockrate value
* Profiling: if profiling is active when the clock changes, let the user
know the results may be inaccurate.
