as clean on shutdown and move that action from shutdown_pre_sync stage to
shutdown_post_sync to avoid extra flapping.
ZFS tends to not close devices on shutdown, that doesn't allow GEOM RAID
to shutdown gracefully. To handle that, mark volume as clean just when
shutdown time comes and there are no active writes.

- Teach find_best_mtu_idx() to deal with IPv6 endpoints.
- Install correct protosw in offloaded TCP/IPv6 sockets when DDP is
enabled.
- Move set_tcp_ddp_ulp_mode to t4_tom.c so that t4_tom.h can be included
without having to drag in t4_msg.h too. This was bothering the iWARP
driver for some reason.

- Add full support for IPv6 addresses.
- Read the size of the L2 table during attach. Do not assume that PCIe
physical function 4 of the card has all of the table to itself.
- Use FNV instead of Jenkins to hash L3 addresses and drop the private
copy of jhash.h from the driver.

ARM EABI syscall calling convention.
The current ABI encodes the syscall number in the instruction. This causes
issues with the thumb mode as it only has 8 bits to encode this value and
we have too many system calls and by using a register will simplify the
code to get the syscall number in the kernel.
With the ARM EABI we reuse the Linux calling convention by storing the
value in r7. Because of this we use both methods to encode the syscall
number in this function.
Set the v_hash for a new vnode in the getnewvnode() to the value
calculated based on the vnode structure address. Filesystems using
vfs_hash_insert() override the v_hash using the standard formula of
(inode_number + mnt_hashseed). For other filesystems, the
initialization allows the vfs_hash_index() to provide useful hash too.

existing nullfs vnode by the lower vnode is only 16 slots. Since the
default mode for the nullfs is to cache the vnodes, hash has extremely
huge chains.
Size the nullfs hashtbl based on the current value of

Implement an FDT attachment for altera_avgen(4).
Portions of the changeset updating DTS and device.hints will be merged

Rework altera_avgen(4) to cleanly(ish) separate nexus bus
attachment from the driver itself. This should allow us to
plug in an fdt attachment more easily.

Start restructuring of altera_avgen(4) so that it can have an FDT

disks should be rebuilt. Our rebuild code is same time disk-centric. To
handle this situation properly check all disks for RBLD flags, and if no
disk specified try rebuild/resync all of them except newly inserted.
Windows driver uses such migration when it creates new arrays. While GEOM
RAID has no mechanism to implement migration in general case, this specifc
case still can be handled easily via degraded RAID1 creation followed by
regular rebuild.

unmerged BERI DTS files) to head:
Use the OFW compatible string "mips,mips4k" rather than
"mips4k,cp0" for interrupt control using MIPS4k CP0.
Suggested by: thompsa
Implement a MIPS FDT PIC decode routine to use when no PIC has been
configured, which assumes a cascade back to the nexus bus (e.g.,
the on-board CP0 interrupt management parts on the MIPS). If the
soc bus in a MIPS DTS file is declared as "mips4k,cp0"-compatible,
then this will be enabled. This is sufficient to allow IRQs to be
configured on BERI.

Provided a bus_space implementation for FDT, modelled on
bus_space_generic, but with a local version of the map address
routine that does a P->V translation, as is the case with NLM's
similar routine for XLP. It's not clear to me that this is the
right solution -- possibly this belongs in simplebus -- however,
it is sufficient to get the DE4 LED driver working.

In a sign of weakness, replicate the MIPS bus_space_generic.c to
produce a new FDT version, which will perform necessary address
space translation for bus_space -- the solution used in NLM's MIPS
FDT support, but possibly not quite the right thing. This is
inconsistent with regular I/O via the nexus and the generic
bus_space, which instead perform translation via pmap_mapdev()
when a resource is activated. However, it will work while I
attempt to identify what the right way to reconcile possible
approaches.
(Another approach might be to make simplebus use Nexus's activate
routine instead of a generic one?)

Add code so that the BERI boot process can ask the kernel linker for
DTB blobs that may have been left for it by the boot loader, as done
on PowerPC and ARM. This will require both a more mature boot
loader, and more mature boot loader argument passing mechanism,
than currently supported on BERI.
