case it fully constructed, but for half-constructed too, so have no
other choice to pass original pattern from glob() down to globextend()
instead of attempt to reconstruct I implement previously.
2) Instead of copy&paste the same big enough code, make function for it:
globfinal().
Chelsio NICs are a bit unique compared to some other NICs in that they
expose different functionality on different physical functions. In
particular, PF4 is used to manage the NIC interfaces ('t4nex' and 't5nex').
However, PF4 is not able to create VF devices. Instead, VFs are only
supported by physical functions 0 through 3. This commit adds 't4iov'
and 't5iov' drivers that attach to PF0-3.
One extra wrinkle is that the iov devices cannot enable SR-IOV until the
firwmare has been initialized by the main PF4 driver. To handle this
case, a new t4_if kobj interface has been added to permit cross-calls
between the PF drivers. The PF4 driver notifies sibling drivers when it
is fully attached. It also requests sibling drivers to detach before it
detaches. Sibling drivers query the PF4 driver during their attach
routine to see if it is attached. If not, the sibling drivers defer
their attach actions until the PF4 driver informs them it is attached.
VF devices are associated with a single port on the NIC. VF devices
created from PF0 are associated with the first port on the NIC, VFs
from PF1 are associated with the second port, etc. VF devices can
only be created from a PF device that has an associated port. Thus,
on a 2-port card, VFs are only supported on PF0 and PF1.

If a driver sends an malformed or disallowed work request, the firmware
responds with a work request error. Previously the driver treated this is
as an unexpected message and panicked. Now it decodes the error message
to aid in debugging.

The asynchronous I/O changes made previously result in different
behavior out of the box. Previously all AIO requests failed with
ENOSYS / SIGSYS unless aio.ko was explicitly loaded. Now, some AIO
requests complete and others ("unsafe" requests) fail with EOPNOTSUPP.
Reword the introductory paragraph in aio(4) to add a general
description of AIO before describing the vfs.aio.enable_unsafe sysctl.
Remove the ENOSYS error description from aio_fsync(2), aio_read(2),
and aio_write(2) and replace it with a description of EOPNOTSUPP.
Remove the ENOSYS error description from aio_mlock(2).
Log a message to the system log the first time a process requests an
"unsafe" AIO request that fails with EOPNOTSUPP. This is modeled on
the log message used for processes using the legacy pty devices.

A positive leap second will be introduced at the end of December 2016.
The sequence of dates of the UTC second markers will be:
2016 December 31, 23h 59m 59s

The difference between UTC and the International Atomic Time TAI is:
from 2015 July 1, 0h UTC, to 2017 January 1 0h UTC : UTC-TAI = - 36s

The addition of the referenceCount to __cxa_allocate_exception put the
unwindHeader at offset 0x58 in __cxa_exception, but it requires 16-byte
alignment. In order to avoid changing the current __cxa_exception ABI
(and thus breaking its consumers), add explicit padding in the
allocation routines (and account for it when freeing).
This is intended as a lower-risk change for FreeBSD 11. A "more correct"
fix should be prepared for upstream and -CURRENT.

Upstream commit r24759 (efed563) prefixed some symbols with rk_, but
introduced 6 duplicate symbols in the version script (because the
rk_-prefixed versions of the symbols were already present).
Two notes:
- I allow AIO on reclaimed vnodes, since it is deterministically terminated
fast.
- devfs mounts are marked as MNT_LOCAL, but device vnodes have type
VCHR, so the slow device io is not allowed.

globexp1() recursive calls, but glob0() was not supposed to be called
repeatedly in the original code. It finalize results by possible adding
original pattern for no match case, may return GLOB_NOMATCH error and
by sorting all things. Original pattern adding or GLOB_NOMATCH error
can happens each time glob0() called repeatedly, and sorting happens
for one item only, all things are never sorted. Second, f.e. "a{a"
pattern does not match "a{a" file but match "a" file instead
(just one example, there are many). Third, some errors (f.e. for limits
or overflow) can be ignored by GLOB_BRACE code because it forces return (0).
Add non-finalizing flag to glob0() and make globexp0() wrapper around
recursively called globexp1() to finalize things like glob0() does.
Reorganize braces code to work correctly.
2) Don't allow MB_CUR_MAX * strlen overallocation hits GLOB_LIMIT_STRING
