Increase the size of devd's client socket's send buffer from the
	default (8k) to 128k.  This prevents clients from getting
	POLLHUPped during event storms.  For example, during zpool creation,
	the kernel emits a resource.fs.zfs.statechange event for every vdev
	in the pool.  A 128k buffer is large enough to hold the statechange
	events for a pool with nearly 800 drives.

d7ee8f3e6e Apply patch from upstream Heimdal for encoding fix
RFC 4402 specifies the implementation of the gss_pseudo_random()
function for the krb5 mechanism (and the C bindings therein).
The implementation uses a PRF+ function that concatenates the output
of individual krb5 pseudo-random operations produced with a counter
and seed.  The original implementation of this function in Heimdal
incorrectly encoded the counter as a little-endian integer, but the
RFC specifies the counter encoding as big-endian.  The implementation
initializes the counter to zero, so the first block of output (16 octets,
for the modern AES enctypes 17 and 18) is unchanged.  (RFC 4402 specifies
that the counter should begin at 1, but both existing implementations
begin with zero and it looks like the standard will be re-issued, with
test vectors, to begin at zero.)

This is upstream's commit f85652af868e64811f2b32b815d4198e7f9017f6,
from 13 October, 2013:
% Fix krb5's gss_pseudo_random() (n is big-endian)
%
% The first enctype RFC3961 prf output length's bytes are correct because
% the little- and big-endian representations of unsigned zero are the
% same.  The second block of output was wrong because the counter was not
% being encoded as big-endian.
%
% This change could break applications.  But those applications would not
% have been interoperating with other implementations anyways (in
% particular: MIT's).

a2907c1e4c I caught the following snippet at the end of my /var/log/bsdinstall_log:
===
DEBUG: Running installation step: services
local: Not in a function
/usr/libexec/bsdinstall/services: cannot create  : Read-only file system
/usr/libexec/bsdinstall/services: /tmp/bsdinstall/etc/rc.conf.services: \
 Permission denied
===
The `local: Not in a function' is obvious, and was introduced by myself in
SVN revision 256348.

The latter two are caused by the attempt to use "\" to continue the line
after using the ">>" redirect. This appears to attempt to write a file with
the name " " in the current directory and subsequently attempts to execute
the file that was originally intended for writing (which is not executable;
hence the `Permission denied'). That was introduced in SVN r228192 about
2 years ago, apparently unnoticed until I started going over the debug
outputs very carefully.

03e85c2d9b sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c
When a da or ada device dissappears, outstanding IOs fail with
	ENXIO, not EIO.  The check for EIO was probably copied from Illumos,
	where that is indeed the correct errno.

	Without this change, pulling a busy drive from a zpool would usually
	turn it into UNAVAIL, even though pulling an idle drive would turn
	it into REMOVED.  With this change, it is REMOVED every time.

	Also, vdev_geom_io_intr shouldn't do zfs_post_remove, because that
	results in devd getting two resource.fs.zfs.removed events.  The
	comment said that the event had to be sent directly instead of
	through the async removal thread because "the DE engine is using
	this information to discard prevoius I/O errors".  However, the fact
	that vdev_geom_io_intr was never actually sending the events until
	now, and that vdev_geom_orphan never sent them at all, and that
	vdev_geom_orphan usually gets called about 2 seconds after the
	actual removal, means that FreeBSD's userland can cope with a late
	event just fine.

fb7844278f Create own free list for each of the first 32 possible allocation sizes.
In case of 4K allocation quantum that means for allocations up to 128K.

With growth of memory fragmentation these lists may grow to quite a large
sizes (tenths and hundreds of thousands items).  Having in one list items
of different sizes in worst case may require full linear list traversal,
that may be very expensive.  Having lists for items of single size means
that unless user specify some alignment or border requirements (that are
very rare cases) first item found on the list should satisfy the request.

While running SPEC NFS benchmark on top of ZFS on 24-core machine with
84GB RAM this change reduces CPU time spent in vmem_xalloc() from 8%
and lock congestion spinning around it from 20% to invisible levels.
And that all is by the cost of just 26 more pointers per vmem instance.

If at some point our kernel will start to actively use KVA allocations
with odd sizes above 128K, something may need to be done to bigger lists
also.

leak, but at a much smaller rate due to a race between ateintr and

called from elsewhere.  Ensure that we free in-flight packets that
have completed there as well. Also remove needless check for NULL on

cfc6ad9bc6 Migrate tools/regression/bin/ tests to the new layout.
This change is a proof of concept on how to easily integrate existing
tests from the tools/regression/ hierarchy into the /usr/tests/ test
suite and on how to adapt them to the new layout for src.

To achieve these goals, this change:

- Moves tests from tools/regression/bin/<tool>/ to bin/<tool>/tests/.
- Renames the previous regress.sh files to legacy_test.sh.
- Adds Makefiles to build and install the tests and all their supporting
  data files into /usr/tests/bin/.
- Plugs the legacy_test test programs into the test suite using the new
  TAP backend for Kyua (appearing in 0.8) so that the code of the test
  programs does not have to change.
- Registers the new directories in the BSD.test.dist mtree file.

When the guest is bringing up the APs in the x2APIC mode a write to the

VM_EXITCODE_SPINUP_AP. This gets SMP guests working again with x2APIC.

b3c6aee1f5 Fix detection of EOF in kern_physio(). If bio_length was clipped by
the excess code in g_io_check(), bio_resid is also truncated by
g_io_deliver().  As result, bufdonebio() assigns truncated value to
the buffer b_resid field.

Use the residual bio_completed to calculate buffer b_resid from
b_bcount in bufdonebio(), instead of bio_resid, calculated from
bio_length in g_io_deliver().

The issue is seemingly caused by the code rearrange into g_io_check(),
which is not present in stable/10.  The change still looks as the
useful change to have in 10 nevertheless.
