In dnode_children_t, use C99's "[]" idiom for declaring the variable
sized array dnc_children at the end of the structure.
This prevents the compiler from mistakenly optimizing away accesses
beyond the array's defined size.

This prevents recursion of vdev_queue_io_done as per r265321 but

We now use zio_interrupt(zio) and return ZIO_PIPELINE_STOP instead
of returning ZIO_PIPELINE_CONTINUE from vdev_*_io_start methods.
zio_vdev_io_start now ASSERTS the that vdev_op_io_start returns
ZIO_PIPELINE_STOP to ensure future changes don't reintroduce
ZIO_PIPELINE_CONTINUE returns.

don't need any #ifdef stuff to use atomic_load/store_64() elsewhere in
the kernel. For armv4 the atomics are trivial to implement for kernel
code (just disable interrupts), less so for user mode, so this only has
the kernel mode implementations for now.

In r269223, gethrtime() is used as creation time of dbuf, which in turn
acts as portion of lookup key to maintain AVL invariant where there can
not be duplicate items. Before this change, gethrtime() have preferred
better execution time by sacrificing precision, which may lead to panic
on busy systems with:
panic: avl_find() succeeded inside avl_add()

value shared across multiple cores is with atomic_load_64() and
atomic_store_64(), because the normal 64-bit load/store instructions
are not atomic on 32-bit arm. Luckily the ldrexd/strexd instructions
that are atomic are fairly cheap on armv6. Because it's fairly simple
to do, this implements all the ops for 64-bit, not just load/store.

the same values as the -march= command line option. Add support for the
"sec" extension (security extensions).
We've been getting away without support for the sec extension because
it's bogusly enabled even on arches where its presence is optional. This
support for .arch_extension is being added mainly so that we can use the
right directives in our source code, and that helps folks using external
toolchains (and will help us when we finally update our toolchain).
to the ldconfig32 default path. /usr/lib32 is the 32 bit versions of
*current* libraries, while old versions should be able to be in
/usr/lib32/compat, like with /usr/lib/compat. The separation is meant to
keep the compile time default search paths cleaner.
The rss_key[] array in netinet/in_rss.c has the bytes in incorrect
order. This results in the RSS test vectors in the Microsft RSS spec
and Intel NIC specs giving incorrect results, and making it difficult
to verify correct hash operation when RSS functionality is added to
new NICs.

We have functions nested within functions, and places where we start a
function then never end it, we just jump to the middle of something else.
We tried to express this with nested ENTRY()/END() macros (which result
in .fnstart and .fnend directives), but it turns out there's no way to
express that nesting in ARM EHABI unwind info, and newer tools treat
multiple .fnstart directives without an intervening .fnend as an error.
These changes introduce two new macros, EENTRY() and EEND(). EENTRY()
creates a global label you can call/jump to just like ENTRY(), but it
doesn't emit a .fnstart. EEND() is a no-op that just documents the
conceptual endpoint that matches up with the same-named EENTRY().
This is based on patches submitted by Stepan Dyatkovskiy, but I made some
changes and added the EEND() stuff, so blame any problems on me.

compressed tarball, aka package. The file system assumes that the
files are layed-out in the same order as needed to allow for the
package to be streamed. As such, it does not read an entire package
into memory first.
Some properties of the file system:
o Files that start with '+' are silently skipped. These are found
in FreeBSD package files.
o Files smaller than or equal to 4KB will be cached in memory and
as such allow for some flexibility in accessing files out of
order.
o Files with the .tgz suffix are assumed to be (sub-)packages and
signal the end for a directory scan.

left some of the decisions based on its counterpart, SA_CCB_BUFFER_IO
being random. As a result, propagation of the residual information
for the SPACE command was broken, so the number of filemarks
encountered during a SPACE operation was miscalculated. Consequently,
systems relying on properly tracked filemark counters (like Bacula)
fell apart.
The change also removes a switch/case in sadone() which r256843
degraded to a single remaining case label.
