190d685037 Add vt(4) support to sparc64. The only driver currently present (ofwfb)
provides support for a variety of low-end graphics hardware (SBus adapters,
Mach64, QEMU's framebuffer, XVR-100). A driver for at least the Creator3D
cards will have to be present before this can become the default console
driver.

To test vt(4) on sparc64, set kern.vty=vt at the loader prompt.

c311f7078c When arm 64-bit atomic ops are available, define ARM_HAVE_ATOMIC64. Use
that symbol (which will be correct in both kernel and userland contexts)
rather than just __arm__ to decide whether to use a local implementation.

6a369c018c Don't return ZIO_PIPELINE_CONTINUE from vdev_op_io_start methods
This prevents recursion of vdev_queue_io_done as per r265321 but
using a different method as recommended on the openzfs list.

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.

Cleanup flow in vdev_geom_io_start while I'm here.

Also fix some cases not using SET_ERROR(..)

9d203d4512 Add 64-bit atomic ops for armv4, only for kernel code, mostly so that we
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.

125f68e708 Split gethrtime() and gethrtime_waitfree() and make the former use
nanouptime() instead of getnanouptime().  nanouptime(9) provides more
precise result at expense of being slower.

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()

59561ab3e1 Add 64-bit atomic ops for armv6. The only safe way to access a 64-bit
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.

2d0ef32f84 Teach as(1) to handle the arm .arch_extension pseudo-op, which accepts
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).

6ffcf5d515 Like with /usr/lib + /usr/lib/compat, add the optional /usr/lib32/compat
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.

07b4e38313 Fix byte ordering in default RSS key.
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.

25166187e3 Fix unwind-info errors in our hand-written arm assembler code.
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.

e9759f8bd3 Add pkgfs, a file system implementation for reading files out of a
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.

8d92719522 Fix breakage introduced by r256843: removing the SA_CCB_WAITING bit
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.

5af464bbe0 Ensure that IP's added to CARP always use the CARP MAC
Previously there was a race condition between the address addition
and associating it with the CARP which resulted in the interface
MAC, instead of the CARP MAC, being used for a brief amount of time.

This caused "is using my IP address" warnings as well as data being
sent to the wrong machine due to incorrect ARP entries being recorded
by other devices on the network.
