and embeds it into address. Inside the kernel we keep addresses with
embedded zone id only for two scopes: link-local and interface-local.
For other scopes this function is nop in most cases. To reduce an
overhead of locking, first check that address is capable for embedding.
Also, handle the loopback address before acquire the lock.

This is intended to support reporting FFT results during active channel
scans, for users who would like to fiddle around with writing applications
that do both FFT visualisation _and_ AP scanning.
* add a new ioctl to enable/trigger spectral scan at channel change/reset;
* set do_spectral consistently if it's enabled, so a channel set/reset
will carry forth the correct PHY error configuration so frames
are actually received;
* for NICs that don't do spectral scan, don't bother checking the
spectral scan state on channel change/reset.
Tested:
* AR9280 - STA and scanning;
* AR5416 - STA, ensured that the SS code doesn't panic
Volume Descriptor (section 7.4). In short, upper-case alphanumeric + some
symbols only. While the makefs utility automatically converts the characters,
$LABEL should be consistent in the scripts.

Bump up the heap size to 1MB. With a few kernel modules, libstand
zalloc and userboot seem to want to use ~600KB of heap space, which
results in a segfault when malloc fails in bhyveload.

r241153
Allow the number of FICL dictionary cells to be overridden.
Loading a 7.3 ISO with userboot/amd64 takes up 10035 cells,
overflowing the long-standing default of 10000.
Bump userboot's value up to 15000 cells.

- Missing PTE_SYNC in pmap_kremove caused memory corruption
in userland applications
- Fix lack of cache flushes when using special PTEs for zeroing or
copying pages. If there are dirty lines for destination memory
and page later remapped as a non-cached region actual content
might be overwritten by these dirty lines when cache eviction
happens as a result of applying cache eviction policy or because
of wbinv_all call.

This change was originally intended to account for test kthreads under
the nvmecontrol process, but jhb indicated it may not be safe to
associate kthreads with userland processes and this could have
unintended consequences.
I did not observe any problems with this change, but my testing didn't
exhaust the kinds of corner cases that could cause problems. It is not
that important to account for these test threads under nvmecontrol, so I
am just reverting this change for now.
On a related note, the part of this patch for <= 7.x fails compilation
so reverting this fixes that too.

Preloaded library could have changed the environment, and
unconditional assingment to the environ undoes the customization.
The binaries needs to be recompiled to get the fix.
Move the common code to set up environ and __progname into the helper.
Note that ia64 possibly not fixed, due to it still using old csu.

Use file name hash as a tree key, handle duplicate keys. Both VOP_LOOKUP

entry offset (cookie) is either file name hash or incremental id in case
of hash collisions (duplicate-cookies). Keep sorted per directory list

Don't fail if previous VOP_READDIR() offset is no longer valid, start

This is a horrible hack to get freefall to compile, and is in dire need
of reconciliation. This antique zlib-1.04 code needs to go away.
If the data frame transmission failures, it may have a node reference
that needs cleaning up.
If the frame is marked as M_ENCAP then it should treat recvif as a node
reference and clear it.
Now - since the mbuf has been freed by calling if_transmit() (even on
failure), the mbuf has to be treated as invalid. Hence why the ifp is
used.
If if_transmit() fails, the node ref may need freeing.
This is based on the same logic used by the ageq, which the mesh code
(re) uses for frames which need to be staged before transmitting.
It also does the same thing - if M_ENCAP is set on the mbuf, it treats
the recvif pointer as a node reference and derefs it.
