23743f6a11 When LK_NOWAIT is passed as argument to process_worklist_item(), this 
does not prevent handle_workitem_remove() from recursing into a blocking
version. Add the dirrem to worklist instead of processing it now if this
is the case.

2d03e33170 Try to stabilize ZFS with regard to memory consumption: 
- Allow to shrink ARC down to 16MB (instead of 64MB).
- Set arc_max to 1/2 of kmem_map by default.
- Start freeing things earlier when low memory situation is detected.
- Serialize execution of arc_lowmem().

I decided to setup minimum ZFS memory requirements to 512MB of RAM and 256MB of
kmem_map size. If there is less RAM or kmem_map, a warning will be printed.
World is cruel, be no better. In other words: modern file system requires
modern hardware:)

From ZFS administration guide:

"Currently the minimum amount of memory recommended to install a Solaris
 system is 512 Mbytes. However, for good ZFS performance, at least one
 Gbyte or more of memory is recommended."

52124c7f1c Reduce diff against vendor - we have now stronger check for "mutex already 
initialized", so we can go back to kmem_alloc().

b47888ceba Add the trunk(4) driver for providing link aggregation, failover and fault 
tolerance.  This driver allows aggregation of multiple network interfaces as
one virtual interface using a number of different protocols/algorithms.

failover    - Sends traffic through the secondary port if the master becomes
              inactive.
fec         - Supports Cisco Fast EtherChannel.
lacp        - Supports the IEEE 802.3ad Link Aggregation Control Protocol
              (LACP) and the Marker Protocol.
loadbalance - Static loadbalancing using an outgoing hash.
roundrobin  - Distributes outgoing traffic using a round-robin scheduler
              through all active ports.

This code was obtained from OpenBSD and this also includes 802.3ad LACP support
from agr(4) in NetBSD.

6429a5cb9b Fix a compiler warning so hash.h can be included in the kernel. This changes 
the args for hash32_stre and hash32_strne but there are no consumers in the
base system and openbgpd does not use it which the initial import was for.

a363f67a81 Restore the locking for the sleep/wakeup to avoid waiting an extra 1 sec 
if a race was lost.  We're still single-threaded at this point, but just
be safe for the future.

6b1e469ea5 Clean up the root mount and mount wait code. No mutexes are needed here 
since a spurious wakeup() is the only possible outcome and this is fine in
the BSD programming model.

24bda1641f Instead of detecting if lock is already initialized based on standard 1 bit 
check, use more accurate 13 bits check. We had too many false-positives with
the standard check.

c2cda60911 prison_free() can be called with a mutex held. This wasn't a problem until 
I converted allprison_mtx mutex to allprison_lock sx lock. To fix this LOR,
move prison removal to prison_complete() entirely. To ensure that noone
will reference this prison before it's beeing removed from the list skip
prisons with 'pr_ref == 0' in prison_find() and assert that pr_ref has to
greater than 0 in prison_hold().
