this is is crucial at least for the latter.
What happens is that attaching uart(4) to scc(4) causes the SAB 82532 to
"receive" something and trigger a SER_INT_RXREADY interrupt, given that
at least fast/filter interrupts are already enabled. Prior to r253161,
uart_bus_ihand() was set up at this point and handled that condition,
i. e. read the RX FIFO and issued a Receive Message Complete.
Now, uart_bus_ihand() and uart_intr() are setup after attaching uart(4),
leaving the SER_INT_RXREADY interrupt triggered during the latter to
be handled by the iclear method. However, with that method not implement,
this in turn causes SAB 82532 to not issue any further SER_INT_RXREADY
interrupts until the RX FIFO is full again. Thus, 15 received bytes go
to nowhere, given that "the other half" of the RX FIFO is used for status
information. Hence, implementing sab82532_bfe_iclear() fixes things again.
Potentially, the same problem exists for QUICC.

- mbuf reused after an RX_COPY optimized operation can sometimes have
a bogus cached address, resulting in TCP hangs. Add critical save points
to the cached address. Thanks to Michael and the team at Verisign for
finding this problem.
- A couple more spots where the rxbuf->flags member should be cleared just
to be sure no incorrect RX_COPY state is left around. Thanks to Adrian
for tracking these down.
- Remove the rearm_queues function from the driver, this was found to be
responsible for some out-of-order packets by Verisign, and was always a
bandaid, with the other fixes in this delta the bandaid can finally be
removed.
- In the other/link interrupt handler the entire state of the EICS register
was being writen back into EICR (which clears causes and thus re-enables
those interrupts), this was wrong, so now mask off the queue portion of
the register value, so we only clear the other/link interrupt we intend.
Marc from Verisign found this.
- Make the SFP+ unsupported option tuneable now, by customer request.
- Finally, just a couple of minor DEBUG string fixes.
I want to call out and thank all the participants in the 10G community/Intel

This was exposed with AP spinup of Linux, and
booting OpenBSD, where the CR0 register is unconditionally
written to prior to the longjump to enter protected
mode. The CR-vmexit handling was not updating CPU state which
resulted in a vmentry failure with invalid guest state.
A follow-on submit will fix the CPU state issue, but this
fix prevents the CR-vmexit prior to entering protected
mode by properly initializing and maintaining CR* state.

other than the one specified by the BOOTP server. This configures NFS
using the BOOTP protocol while also respecting other root-path options such
as setting vfs.root.mountfrom in the environment or using the RB_DFLTROOT
boot option. It allows you to override the root path provided by the
server, or to supply a root path when the server provides IP configuration
but no root path info.
This maintains the historical BOOTP_NFSROOT behavior of panicking on a
failure to mount the root path provided by the server, unless you've
provided an alternative via the ROOTDEVNAME kernel option or by setting
vfs.root.mountfrom. The behavior of panicking when given no other options
is preserved because it amounts to a bit of a retry loop that could
eventually recover from a transient network or server problem.
The user can now override the root path from loader(8) even if the
kernel is compiled with BOOTP_NFSROOT. If vfs.root.mountfrom is set in
the environment it is used unconditionally -- it always overrides the
BOOTP info. If it begins with [old]nfs: then the BOOTP code uses it
instead of the server-provided info. If it specifies some other
filesystem then the bootp code will not panic like it used to and the code
in vfs_mountroot.c will invoke the right filesystem to do the mount.
If the kernel is compiled with the ROOTDEVNAME option, then that name is
used by the BOOTP code if either
* The server doesn't provide a pathname.
* The boothowto flags include RB_DFLTROOT.
The latter allows the user to compile in alternate path in ROOTDEVNAME
such as ufs:/dev/da0s1a and boot from that path by setting
boot_dftlroot=1 in loader(8) or using the '-r' option in boot(8).
The one thing not provided here is automatic failover from a
server-provided path to a compiled-in one without the user manually
requesting that. The code just isn't currently structured in a way that
makes that possible with a lot of rewrite. I think the ability to set
vfs.root.mountfrom and to use ROOTDEVNAME automatically when the server
doesn't provide a name covers the most common needs.
A set of patches submitted by Lars Eggert provided the part I couldn't
figure out by myself when I tried to do this last year; many thanks.

Illumos ZFS issues:
3834 incremental replication of 'holey' file systems is slow

To quote Illumos issue #3888:
When 'zfs recv -F' is used with an incremental recv it rolls
back any changes made since the last snapshot in case new
changes were made to the file system while the recv is in
progress (without -F the recv would fail when it does it's
final check to commit the recv-ed data as the recv-ed data
conflicts with the newly written data).
However, if there is a snapshot taken after the recv began
rolling back to the 'latest' snapshot will not help and the
recv will still fail. 'zfs recv -F' should be extended to
destroy any snapshots created since the source snapshot when
finishing the recv (effectively rolling back through all
snapshots, instead of just to the latest snapshot).

This change allows `zpool clear` to be used again to recover suspended pool.
It seems the only was supposed by the code to restore pool operation after
reconnecting lost disks that were required for data completeness. There
are still cases where `zpool clear` command can just safely stuck due to
deadlocks inside ZFS kernel part, but probably that is better then having
no chances to recover at all.
