The journal is only prepared to handle full-size block numbers, so we
have to adjust freeblk records to reflect the change to a full-size block.
For example, suppose we have a block made up of fragments 8-15 and
want to free its last two fragments. We are given a request that says:
FREEBLK ino=5, blkno=14, lbn=0, frags=2, oldfrags=0
where frags are the number of frags to free and oldfrags are the number
of fragments to keep. To block align it, we have to change it to have a
valid full-size blkno, so it becomes:
FREEBLK ino=5, blkno=8, lbn=0, frags=2, oldfrags=6

Fix various edge cases with rewinddir(), seekdir(), and telldir():
- In the unionfs case, opendir() and fdopendir() read the directory's full
contents and cache it. This cache is not refreshed when rewinddir() is
called, so rewinddir() will not notice updates to a directory. Fix this
by splitting the code to fetch a directory's contents out of
__opendir_common() into a new _filldir() function and call this from
rewinddir() when operating on a unionfs directory.
- If rewinddir() is called on a directory opened with fdopendir() before
any directory entries are fetched, rewinddir() will not adjust the seek
location of the backing file descriptor. If the file descriptor passed
to fdopendir() had a non-zero offset, the rewinddir() will not rewind to
the beginning. Fix this by always seeking back to 0 in rewinddir().
This means the dd_rewind hack can also be removed.
- Add missing locking to rewinddir()
- POSIX says that passing a location returned by telldir() to seekdir()
after an intervening call to rewinddir() is undefined, so reclaim any
pending telldir() cookies in the directory when rewinddir() is called.
- If telldir() is called immediately after a call to seekdir(), POSIX
requires the return value of telldir() to equal the value passed to
seekdir(). The current seekdir code with SINGLEUSE enabled breaks
this case as each call to telldir() allocates a new cookie. Instead,
remove the SINGLEUSE code and change telldir() to look for an existing
cookie for the directory's current location rather than always creating
a new cookie.

Don't try to use the 32-bit drti.o unless the data model is explicitly set
to ILP32. Otherwise dtrace -G will attempt to use it on amd64 if it can't
determine which data model to use, which happens when -64 is omitted and
no object files are provided, e.g. with
# dtrace -G -n BEGIN
This would result in a linker error, but now works properly.
Also remove an unnecessary #ifdef.
Previously the tunables and sysctls had different names for example:
hw.ixgbe.enable_aim => hw.ix.enable_aim
Anyone using ixgbe tunables should ensure they update /boot/loader.conf.
This is a direct commit to stable as the changes to sysctls in head
already fix this issue in a different way.

Review pass through jail.8
Replace usage of "prison" with "jail", since that term has mostly dropped
out of use. Note once at the beginning that the "prison" term is equivalent,
but do not use it otherwise. [1]
Some grammar issues.
Some mdoc formatting fixes.
Consistently use \(em for em dashes, with spaces around it.
Avoid contractions.

10 has a new flex (2.5.37) and the config.h for unbound has been updated to
take this into account. Alas it breaks source upgrade from any version of
9 because flex is not built as a bootstrap-tools (it would be for older
versions).
That means "libunbound/configlexer.c" is built with the old flex but using
config.h for the new one. Build is thus broken going from 9.* to 10.
Make flex a bootstrap-tools entry if host is less than 1000033 to take into
account the flex update in 10.
Tested on both 9.2-RC3 and 9.3 by myself and dim@. Running buildworld in
head but as both 10 and 11 has the new flex, it will not matter.

- Implement fast interrupt handler to save CPU usage.
- Cleanup some register reads and writes to use existing register
access macros.
- Ensure code which only applies to the control endpoint is not run
for other endpoints in the data transfer path.
In r268463, I misplaced a return in demangle(), causing the function to
erroneously skip symbols that were not mangled at all. Fix this by
moving the return into the preceding if block.
While here, simplify the code by letting __cxa_demangle() allocate the
needed space for the demangled symbol. This also fixes a memory leak,
which would occur whenever __cxa_demangle() failed.

Increase default ARC buf_hash_table size. When typical block size is small,
the hash table could be too small, which would lead to long hash chains and
limit performance for cached reads.
A new loader tunable, vfs.zfs.arc_average_blocksize, have been added which
allows users to override the default assumption of average (typical) block
size. Old default was 65536 (64 KiB) and new default is 8192 (8 KiB).
