requires process descriptors to work and having PROCDESC in GENERIC
seems not enough, especially that we hope to have more and more consumers
in the base.

I introduced a bug which initialized global locks
whenever the SCTP stack initialized. This was fixed in
http://svnweb.freebsd.org/changeset/base/258574
by rodrigc@. He just initialized the locks for
the default vnet. This fix reverts to the old
behaviour before r258221, which explicitly makes
sure it is only called once, because this works also on
other platforms.

decides to do nothing.
If this isn't done, then a scan request whilst a scan occurs in an active
channel set or a completed channel set will hang.

This solves GCC/32617 and contributes to reduce differences with
Apple's gcc42.

The freebsd variant of dmu_write_pages is hidden under _KERNEL
to avoid needlessly pulling in vm_page_t declaration.
Besides, this function seems to be useless for ZFS userland counterpart.

ZFS never partially validates or invalidates a page.
The higher level VM should not do that either.
mappedread_sf correct operation depends on a page being either fully
valid or invalid.

While it was brought in r258179 only to fix a build issue,
bringing the rest of the change has the advantage of fixing
GCC/19978.

from OF. Linux does it similar, means they also read the OF values and
display them.
Tested under qemu and real hardware:
cpu0: IBM POWER5+ revision 2.0, 1898.10 MHz
in one of the many layers of indirection and shims through stable/7
in jail_handle_ips(). When it was cleaned up and unified through
kern_jail() for 8.x, the byte order swap was lost.
This only matters for ancient binaries that call jail(2) themselves
internally.
4101 metaslab_debug should allow for fine-grained control
4102 space_maps should store more information about themselves
4103 space map object blocksize should be increased
4104 ::spa_space no longer works
4105 removing a mirrored log device results in a leaked object
4106 asynchronously load metaslab

Note that some tunables have been removed and some new tunables have
been added. Of particular note, FreeBSD-only knob
vfs.zfs.space_map_last_hope is removed as it was a nop for some time now
(after one of the previous merges from upstream).

This API has semantics similar to that of taskqueue_drain but acts on
all tasks that might be queued or running on a taskqueue.
A caller must ensure that no new tasks are being enqueued otherwise this
call would be totally meaningless. For example, if the tasks are
enqueued by an interrupt filter then its interrupt must be disabled.

In illumos all ioctl zio-s are "global" at the moment. That is they act
on a whole disk, e.g. a cache flush command, and thus do not need either
offset or size parameters.
FreeBSD, on the other hand, has support for TRIM command and that
command requires proper offset and size parameters.
Without this fix all TRIM commands act on the start of any disk or
partition used by ZFS destroying any data there.

commit level triggered interrupts would work as long as the pin was not shared
among multiple interrupt sources.
The vlapic now keeps track of level triggered interrupts in the trigger mode
register and will forward the EOI for a level triggered interrupt to the
vioapic. The vioapic in turn uses the EOI to sample the level on the pin and
re-inject the vector if the pin is still asserted.
The vhpet is the first consumer of level triggered interrupts and advertises
that it can generate interrupts on pins 20 through 23 of the vioapic.
