zfs_map_page/zfs_unmap_page are mostly called around potential I/O paths
and it seems to be a not very good idea to do cpu pinning there.

nanobsd will build a system that uses this label (via
/dev/ufs/${NANO_LABEL}sX) in preference to NANO_DRIVE (well, it forces
NANO_DRIVE to be ufs/${NANO_LABEL}). This allows images that will
boot off usb stick or CF card easily well.
There is no change if you don't set this variable.
to growing the filesystem.
Refuse to attach providers where the metadata provider size is
wrong. This makes post-boot attaches behave consistently with
pre-boot attaches. Also refuse to restore metadata to a provider
of the wrong size without the new -f switch. The new -f switch
forces the metadata restoration despite the provider size, and
updates the provider size in the restored metadata to the correct
value.

acl_is_trivial_np(3) properly recognize the new trivial ACLs. From

- Add a single sysctl procedure to all three drivers to read an arbitrary
register (the register is passed as arg2). Use it to replace existing
routines in igb(4) that used a separate routine for each register, and
to add support for missing stats in em(4) and lem(4).
- Move the 'rx_overruns' and 'watchdog_timeouts' stats out of the MAC stats
section as they are driver stats, not MAC counters.
- Simplify the code that creates per-queue stats in igb(4) to use a single
loop and remove duplicated code.
- Properly read all 64 bits of the 'good octets received/transmitted' in
em(4) and lem(4).
- Actually read the interrupt count registers in em(4), and drop the
'host to card' sysctl stats from em(4) as they are not implemented in
any of the hardware this driver supports.
- Restore several stats to em(4) that were lost in the earlier stats
conversion including per-queue stats.
- Export several MAC stats in em(4) that were exported in igb(4) but not
in em(4).
- Export stats in lem(4) using individual sysctls as in em(4) and igb(4).

vm_map_unlock_nodefer() part of the synchronization interface for maps.
Add comments to vm_map_unlock_and_wait() and vm_map_wakeup() describing
how they should be used. In particular, describe the deferred deallocations
issue with vm_map_unlock_and_wait().
Redo the implementation of vm_map_unlock_and_wait() so that it passes
along the caller's file and line information, just like the other map
locking primitives.

Instead of adding custom checks to wait for DCD on open(), just modify
the termios structure to set CLOCAL. This means SIGHUP is no longer
generated when losing DCD as well.

The original patch was questioned by Kirk as it forces the filesystem
to do excessive work initialising inodes on first use, and was never
MFC'd. This change mimics the newfs(8) approach of zeroing two
blocks of inodes for each new cylinder group.

it frees local locks correctly upon close. In order for
nfsrv_localunlock() to work correctly, the lock can no longer be in
the lockowner's stateid list. As such, nfsrv_freenfslock() has to
be called before nfsrv_localunlock(), to get rid of the lock structure
on the lockowner's stateid list. This only affected operation when
local locks (vfs.newnfs.enable_locallocks=1) are enabled, which is
not the default at this time.
