Add a new build option, MAN_UTILS. This option lets you control building
utilities and related support files for manual pages, which were previously
controlled by MAN. For POLA, the default depends on MAN, i.e., WITHOUT_MAN
implies WITHOUT_MAN_UTILS and WITH_MAN implies WITH_MAN_UTILS.
Note this patch implicitly fixes a documentation bug of src.conf(5), which
says WITHOUT_MAN may be used to not build manual pages while it was also
disabling some utilities for manual pages.

Use the iflladdr_event event to keep the mac address on the vap in sync with
the parent wirless interface. If the user passed in a mac address or it was
autogenerated then flag this to avoid trashing it on update.
This will fix wlan+lagg in a post vap world.
Declare a new EVENTHANDLER called iflladdr_event which signals that the L2
address on an interface has changed. This lets stacked interfaces such as
vlan(4) detect that their lower interface has changed and adjust things in
order to keep working. Previously this situation broke at least vlan(4) and
lagg(4) configurations.
The EVENTHANDLER_INVOKE call was not placed within if_setlladdr() due to the
risk of a loop.

Do not hold the lock over if_setlladdr() as it calls into the interface driver
init routine.
- fixes a bug that it didn't initialize the ratectl after association;
so ni_txrate returned 0 which is a invalid result.

When configuring hwpmc to use the EXT_SNOOP event, only send a default
cachestate qualifier on the Atom processor. Other Intel processors do not
accept a cachestate qualifier and currently hwpmc will return EINVAL if you
try to use the EXT_SNOOP event on those processors
Approved by: emaste (mentor)
When configuring a system-wide couting PMC, hwpmc was incorrectly logging
process mappings for that PMC. Nothing ever reads pmc logs out of a
counting PMC, so the log buffers were leaked when the PMC was
deconfigured. The process mappings are only useful for sampling PMCs
anyway, so only log the mappings if the PMC is a sampling PMC.
This bug would cause allocating sample-mode PMCs to fail with ENOMEM
after allocating several counting-mode PMCs.

Eventhough r203504 eliminates taste traffic provoked by vdev_geom.c,
ZFS still like to open all vdevs, close them and open them again,
which in turn provokes taste traffic anyway.
I don't know of any clean way to fix it, so do it the hard way - if we can't
open provider for writing just retry 5 times with 0.5 pauses. This should
elimitate accidental races caused by other classes tasting providers created on
top of our vdevs.

r208142:
The whole point of having dedicated worker thread for each leaf VDEV was to
avoid calling zio_interrupt() from geom_up thread context. It turns out that
when provider is forcibly removed from the system and we kill worker thread
there can still be some ZIOs pending. To complete pending ZIOs when there is
no worker thread anymore we still have to call zio_interrupt() from geom_up
context. To avoid this race just remove use of worker threads altogether.
This should be more or less fine, because I also thought that zio_interrupt()
does more work, but it only makes small UMA allocation with M_WAITOK.
It also saves one context switch per I/O request.

Add task structure to zio and use it instead of allocating one.
This eliminates the only place where we can sleep when calling zio_interrupt().
As a side-effect this can actually improve performance a little as we
allocate one less thing for every I/O.

Fix a long-standing bug in the PowerPC OFW call function on SMP machines
by forcing all secondary CPUs into a busy wait with interrupts off during
the call. This bug caused ofwdump -a to hang the system.
Following section 8.4 of the Open Firmware PowerPC processor binding,
the firmware is free to overwrite the system interrupt handlers during
OF calls, restoring the OS handlers on exit. On single CPU systems, this
process is invisible to the operating system. On multiple CPU systems,
taking any exception on a secondary CPU while an OF call is in progress
ends with that exception vectored into OF, resulting in a slow movement
of the entire system into firmware context and a machine hang.
On PowerMac11,2 and (presumably) PowerMac12,1, we need to quiesce the
firmware in order to take over control of the SMU. Without doing this,
the firmware background process doing fan control will run amok as we
take over the system and crash the management chip.
This is limited to these two machines because our kernel is heavily
dependent on firmware accesses, and so quiescing firmware can cause
nasty problems.
Add support for the U4 PCI-Express bridge chipset used in late-generation
Powermac G5 systems. MSI and several other things are not presently
supported.
