Use real atomic operations for sparc64.
MFC ZFS version 13. This includes the changes by pjd (see original message2009-05-20T23:34:59ZKip Macykmacy@FreeBSD.org2009-05-20T23:34:59Zurn:sha1:5c763151888b2933f081f83fd59df6a6f66d98bd
below) as well as the following:
- the recurring deadlock was fixed by deferring vinactive to a dedicated thread
- zfs boot for all pool types now works
Submitted by: dfr
- kmem now goes up to 512GB so arc is now limited by physmem
- the arc now experiences backpressure from the vm (which can be too
much - but this allows ZFS to work without any tunables on amd64)
- frequently recurring LOR in the ARC fixed
- zfs send coredump fix
- fixes for various PRs

Diff to previous 177698
Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.
This bring huge amount of changes, I'll enumerate only user-visible changes:
- Delegated Administration
Allows regular users to perform ZFS operations, like file system
creation, snapshot creation, etc.
- L2ARC
Level 2 cache for ZFS - allows to use additional disks for cache.
Huge performance improvements mostly for random read of mostly
static content.
- slog
Allow to use additional disks for ZFS Intent Log to speed up
operations like fsync(2).
- vfs.zfs.super_owner
Allows regular users to perform privileged operations on files stored
on ZFS file systems owned by him. Very careful with this one.
- chflags(2)
Not all the flags are supported. This still needs work.
- ZFSBoot
Support to boot off of ZFS pool. Not finished, AFAIK.

- Snapshot properties
- New failure modes
Before if write requested failed, system paniced. Now one
can select from one of three failure modes:
Before if write requested failed, system paniced. Now one
can select from one of three failure modes:
- panic - panic on write error
- wait - wait for disk to reappear
- continue - serve read requests if possible, block write requests
- Refquota, refreservation properties
Just quota and reservation properties, but don't count space consumed
by children file systems, clones and snapshots.
- Sparse volumes
ZVOLs that don't reserve space in the pool.
- External attributes
Compatible with extattr(2).
- NFSv4-ACLs
Not sure about the status, might not be complete yet.

- Creation-time properties
- Regression tests for zpool(8) command.

DTrace support.
Note that this defaults the 'make buildkernel' to build with CTF data so
that the release kernel and modules are DTrace-able.

and changes WITHOUT_LIBPTHREADS to mean with neither threading libs.

if not equal or there is no provider with such name, find provider with
remembered ident and don't care about the name.
