attachment of i2c devices needed by hdmi.
The hdmi init also uses an intrhook callback to defer initialization, and if
the hdmi callback runs first, the i2c devices will not yet have registered
their device_t in association with their FDT phandle, which allows cross-
device references on FDT systems.
Now the hdmi deferred init checks for the i2c device registration, and if
it's not complete yet, it registers as an eventhandler watching for newbus
attach events. When the i2c device eventually attaches, the hdmi driver
unregisters from watching further events, and continues with the hdmi init.
Because the function signatures for an intrhook callback and an event
handler callback are the same, a single function is used for both callbacks.
Reported by: Russell Haley <russ.haley@gmail.com>
The detach case is slightly complicated by the fact that some in-kernel
consumers may want to know before a device detaches (so they can release
related resources, stop using the device, etc), but the detach can fail. So
there are pre- and post-detach notifications for those consumers who need to
handle all cases.
A couple salient comments from the review, they amount to some helpful
documentation about these events, but there's currently no good place for
such documentation...
Note that in the current newbus locking model, DETACH_BEGIN and
DETACH_COMPLETE/FAILED sequence of event handler invocation might interweave
with other attach/detach events arbitrarily. The handlers should be prepared
for such situations.
Also should note that detach may be called after the parent bus knows the
hardware has left the building. In-kernel consumers have to be prepared to
cope with this race.

When the EVENTHANDLER(9) subsystem was created, it was a documented feature
that an eventhandler callback function could safely deregister itself. In
r200652 that feature was inadvertantly broken by adding drain-wait logic to
eventhandler_deregister(), so that it would be safe to unload a module upon
return from deregistering its event handlers.
There are now 145 callers of EVENTHANDLER_DEREGISTER(), and it's likely many
of them are depending on the drain-wait logic that has been in place for 8
years. So instead of creating a separate eventhandler_drain() and adding it
to some or all of those 145 call sites, this creates a separate
eventhandler_drain_nowait() function for the specific purpose of
deregistering a callback from within the running callback.

v3.5.05 release for Linux.
T6 Firmware
++++++++++++
================================================================================
Version : 1.16.63.0
Date : 09/29/2017
================================================================================
Fixes
-----
BASE:
- Fixed a fw crash when configured traffic rate limit is less than 10kbps.
- Fixed traffic rate limiting for smaller traffic rate value.
ETH:
- Fixed 40G link failure when interface is toggled.
- Fixed adapter crash when interface is toggled during traffic.
- Fixed 25G link failure when PEER only supports consortium mode autoneg
for 25G.
- Fixed 100G optics link failure when cable is plugged in after bringing up
the interface.
- Enable RS FEC as default if speed is 100G.
- Fixed DCBX configuration refresh failure.
OFLD
- Fixed 0B iWARP ingress read failure.
- Fixed iWARP SRQ reuse failure.
FOiSCSI:
- Fixed vlan interface ping failure.
- Fixed target discovery failures.
- Fixed mutual chap login failure.
================================================================================
Version : 1.16.59.0
Date : 09/05/2017
================================================================================
FIXES
-----
BASE:
- Fixed fw crash caused by MC parity error in SO adapters.
- Generate Timer0Int interrupt if fw crashes due to unaligned access error. Host
driver must look into PCIE_FW register to see if any fw fatal error has
encountered. If PCIE_FW doesn't indicate any error then driver must ignore this
interrupt.
- Fixed receive buffer threshold settings which was resulting in error frames on
receive side.
ETH:
- Fixed an issue in connection traffic shaping when
FLOWC_WR->FW_FLOWC_MNEM_SCHEDCLASS is not received in first WR on the connection.
- Fixed link failure when speed is changed from 10G-1G-10G due to incorrect flag
check.
- Fixed improper LED behaviour for blink test and when traffic is running.
- Removed storage of previous fec settings from fw. Driver needs to pass the user
settings whenever a new module is plugged in as fw resets these when a module is
unplugged.
OFLD
- OVS offload: TP cache is flushed periodically to get the accuate filters stats
(hit count).
ENHANCEMENTS
------------
BASE:
- Ring backbone feature added. New FW_PARAMS_PARAM_DEV_RING_BACKBONE param type

enables the memfree support (256 connections) for iwarp.

- Added the ability to allow only selected speeds to be advertised during auto
negotiation.
- Increased port capability from 16 to 32 bits to support more speeds.

bit port capability.
OFLD:
- RDMA Write with immediate support added (iwarp 2.0 feature)

If VIMAGE is present we can start jails with their own pf instance. This
makes it fairly easy to run tests.
For example, this basic test verifies that drop/pass and icmp
classification works. It's a basic sanity test for pf, and hopefully an
example on how to write more pf tests.
The tests are skipped if VIMAGE is not enabled.
This work is inspired by the GSoC work of Panagiotes Mousikides.

'last' is the sector number of the last usable sector. Sector
numbers start with 0. As such, 'last' is always 1 less than
the count of sectors and aligning 'last' down as-is means that
the number of free sectors is pessimized by 'alignment - 1' if
the number of usable sectors was already a multiple of the
alignment. Consequently, gpart(8) failed to create a partition
when the alignment and size were such that it would extend to
the end of the disk.
Previously it just didn't work at all - kvm_getprocs(3) doesn't update
the &nentries when it returns NULL. The end result was that ps(1) showed

The zfs diff command presents a description of the changes that have occurred
to files within a filesystem between two snapshots. If a file is renamed, the
tool is capable of reporting this, e.g.:
cd /some/zfs/dataset/subdir
mv file0 file1
Will result in a diff record like:
R /some/zfs/dataset/subdir/file0 -> /some/zfs/dataset/subdir/file1
Unfortunately, it seems that rename detection only uses the base filename to
determine if a file has been renamed or simply modified. This leads to
misreporting only the original filename, omitting the more relevant destination
filename entirely. For example:
cd /some/zfs/dataset/subdir
mv file0 ../otherdir/file0
Will result in a diff entry:
M /some/zfs/dataset/subdir/file0
But it should really emit:
R /some/zfs/dataset/subdir/file0 -> /some/zfs/dataset/otherdir/file0

Transition all boards that support arm cortex CPUs to armv7. This
leaves two armv6 kernels in the tree. RPI-B, which uses the BCM2835
which has a ARM1176 core, and VERSATILEPB, which is a qemu board setup
around the time RPI-B went in. Copy std.armv6 to std.armv7, even
though that duplicates a lot of stuff. More work needs to be done to
sort out the duplication.

Make armv7 as a new MACHINE_ARCH.
Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.
Support armv7 as a new valid MACHINE_ARCH (and by extension
TARGET_ARCH).
Add armv7 to the universe build.
