andrew Remove the armv6eb architecture as it is unused, and almost certainly

@DimitryAndric DimitryAndric Pull in r191165 from upstream llvm trunk:
  ISelDAG: spot chain cycles involving MachineNodes

  Previously, the DAGISel function WalkChainUsers was spotting that it
  had entered already-selected territory by whether a node was a
  MachineNode (amongst other things). Since it's fairly common practice
  to insert MachineNodes during ISelLowering, this was not the correct

  Looking around, it seems that other nodes get their NodeId set to -1
  upon selection, so this makes sure the same thing happens to all
  MachineNodes and uses that characteristic to determine whether we
  should stop looking for a loop during selection.

  This should fix PR15840.

Specifically, this fixes the long-standing assertion failure when
compiling the multimedia/gstreamer port on i386.  Thanks to Tijl
Coosemans for his help in getting upstream to fix it.

@dag-erling dag-erling Add a setup script for unbound(8) called local-unbound-setup. It
generates a configuration suitable for running unbound as a caching
forwarding resolver, and configures resolvconf(8) to update unbound's
list of forwarders in addition to /etc/resolv.conf.  The initial list
is taken from the existing resolv.conf, which is rewritten to point to
localhost.  Alternatively, a list of forwarders can be provided on the
command line.

To assist this script, add an rc.subr command called "enabled" which
does nothing except return 0 if the service is enabled and 1 if it is
not, without going through the usual checks.  We should consider doing
the same for "status", which is currently pointless.

Add an rc script for unbound, called local_unbound.  If there is no
configuration file, the rc script runs local-unbound-setup to generate

Note that these scripts place the unbound configuration files in
/var/unbound rather than /etc/unbound.  This is necessary so that
unbound can reload its configuration while chrooted.  We should
probably provide symlinks in /etc.

@dag-erling dag-erling Prevent resolvconf from updating /etc/resolv.conf. As Jakob Schlyter
pointed out, having additional nameservers listed in /etc/resolv.conf
can break DNSSEC verification by providing a false positive if unbound
returns SERVFAIL due to an invalid signature.  The downside is that
the domain / search path won't get updated either, but we can live
with that.

There is still aliasing with events delayed by the new precision mechanism,

scottl Update the CAM API for FreeBSD 10:
- Remove the timeout_ch field.  It's been deprecated since FreeBSD 7.0;
  MPSAFE drivers should be managing their own timeout storage.  The
  remaining non-MPSAFE drivers have been modified to also manage their own
  storage, and should be considered for updating to MPSAFE (or removal)
  during the FreeBSD 10.x lifecycle.

- Add fields related to soft timeouts and quality of service, to be used
  in upcoming work.

- Add room for more flags in the CCB header and path_inq structures.

- Begin support for extended 64-bit LUNs.

- Bump the CAM version number to 0x18, but add compat shims.  Tested with
  camcontrol and smartctl.

for. This is useful for software needing to know which architecture a
binary is built for as arm and armv6 have slight differences meaning only
some binaries build for one will work as expected on the other. It is
expected pkgng will be able to make use of this to simplify the logic to
determine which package ABI to use.
