Our libc doesn't implement control method for XDR (only kernel does) and it
will always return failure. Fix this by bringing userland implementation of
xdrmem_control() back. This allow 'zpool import' to work again.

Add support for backing up the old kernel when installing a new kernel
using freebsd-update. This applies to using freebsd-update in "upgrade
mode" and normal freebsd-update on a security branch.
The backup kernel will be written to /boot/kernel.old, if the directory
does not exist, or the directory was created by freebsd-update in a
previous backup. Otherwise freebsd-update will generate a new directory
name for use by the backup. By default symbol files are not backed up
to save diskspace and avoid filling up the root partition.
This feature is fully configurable in the freebsd-update config file,
but defaults to enabled.

Temporarily enhance em(4) and igb(4) hack to take account for IFF_NOARP.
Without this changeset there will be no way to prevent these NICs from
sending ARP, which is harmful in server farms that is configured as
"Direct Server Return" behind a load balancer.
A better fix would remove the whole hack completely but it would be
later than 8.0-RELEASE.

Explicitly line up the CPU state labels with the calculated starting column
that takes into account the width of the largest CPU ID. On systems with
> 10 CPUs the labels for the first 10 CPUs were not lined up properly
otherwise.
Approved by: re (kib)
Remove the dependency on the kernel -- in particular the gctl request to
the GEOM_BSD class -- to translate the absolute offsets in the label to
relative ones. This makes bslabel(8) work correctly with GEOM_PART and
also when the BSD label is nested under arbitrary partitioning schemes.

Fix USB cache sync operations for platforms with non-coherent DMA.
- usb_pc_cpu_invalidate() is called between [consecutive] reads from a device,
so a sequence of BUS_DMASYNC_POSTREAD and _PREREAD should be used. Note we
cannot use or'ed shorthand ( _POSTREAD | _PREREAD) for BUS_DMASYNC flags, as
the low level bus dma sync operation is implementation dependent and we
cannot assume the required order of operations to be guaranteed.
- usb_pc_cpu_flush() is called before writing to a device, so
BUS_DMASYNC_PREWRITE should be used.

Do not try to reevaluate current RX production index on each

- change the interface to flowtable_lookup so that we don't rely on
the mbuf for obtaining the fib index
- check that a cached flow corresponds to the same fib index as the
packet for which we are doing the lookup
- at interface detach time flush any flows referencing stale rtentrys
associated with the interface that is going away (fixes reported
panics)
- reduce the time between cleans in case the cleaner is running at
the time the eventhandler is called and the wakeup is missed less
time will elapse before the eventhandler returns

Backout r193289. r193289 restored page select bits to previous
value instead of blindly resetting it to 0. However, it seems page
select bits of some 88E1116 PHY is initialized to invalid one such
that restoring page select bits after programming broke MII
register access. The correct solution would be reset page select
bits to 0 in PHY attach stage but it would require more testing.
Since we're in BETA stage such a change would be dangerous so just
back it out.
This change should fix nfe(4) breakage on NVIDIA MCP55.

* Change the scope of the ASSERT_ATOMIC_LOAD() from a generic check to
a pointer-fetching specific operation check. Consequently, rename the
operation ASSERT_ATOMIC_LOAD_PTR().
* Fix the implementation of ASSERT_ATOMIC_LOAD_PTR() by checking
directly alignment on the word boundry, for all the given specific
architectures. That's a bit too strict for some common case, but it
assures safety.
* Add a comment explaining the scope of the macro

getcwd() (when __getcwd() fails) works by stating current directory, going up
(..), calling readdir and looking for previous directory inode. In case of
.zfs/ directory this doesn't work, because .zfs/ is hidden by default, so it
won't be visible in readdir output.
Fix this by implementing VPTOCNP for snapshot directories, so __getcwd()
doesn't fail and getcwd() doesn't have to use readdir method.
This fixes /bin/pwd from within .zfs/snapshot/<name>/.
