185ae6d7a3 [PATCH] timer irq driven soft watchdog fix
I seem to have lost this hunk in yesterday's patch.  It brings the
coming-online CPU's softlockup timer up to date so we don't get false-positive
tripups during CPU hot-add.

bc83455bc8 [PATCH] fix DMI onboard device discovery
Attached patch fixes invalid pointer arithmetic in DMI code to make onboard
device discovery working again.

akpm: bug has been present since dmi_find_device() was added in 2.6.14.
Affects ipmi only (I think) - the symptoms weren't described.

akpm: changed to use pointer arithmetic rather than open-coded sizeof.

9f6933be66 V4L/DVB (3599a): Move drivers/usb/media to drivers/media/video
Because of historic reasons, there are two separate directories with
V4L stuff. Most drivers are located at driver/media/video. However, some
code for USB Webcams were inserted under drivers/usb/media.

This makes difficult for module authors to know were things should be.
Also, makes Kconfig menu confusing for normal users.

This patch moves all V4L content under drivers/usb/media to
drivers/media/video, and fixes Kconfig/Makefile entries.

cef2685e00 [IPV4]: Aggregate route entries with different TOS values
When we get an ICMP need-to-frag message, the original TOS value in the
ICMP payload cannot be used as a key to look up the routes to update.
This is because the TOS field may have been modified by routers on the
way.  Similarly, ip_rt_redirect should also ignore the TOS as the router
that gave us the message may have modified the TOS value.

The patch achieves this objective by aggregating entries with different
TOS values (but are otherwise identical) into the same bucket.  This
makes it easy to update them at the same time when an ICMP message is
received.

In future we should use a twin-hashing scheme where teh aggregation
occurs at the entry level.  That is, the TOS goes back into the hash
for normal lookups while ICMP lookups will end up with a node that
gives us a list that contains all other route entries that differ
only by TOS.

2babf9daae [SCTP]: Fix up sctp_rcv return value
I was working on the ipip/xfrm problem and as usual I get side-tracked by
other problems.

As part of an attempt to change the IPv4 protocol handler calling
convention I found that SCTP violated the existing convention.

It's returning non-zero values after freeing the skb.  This is doubly bad
as 1) the skb gets resubmitted; 2) the return value is interpreted as a
protocol number.

This patch changes those return values to zero.

IPv6 doesn't suffer from this problem because it uses a positive return
value as an indication for resubmission.  So the only effect of this patch
there is to increment the IPSTATS_MIB_INDELIVERS counter which IMHO is
the right thing to do.

9f514950bb [NET]: Take RTNL when unregistering notifier
The netdev notifier call chain is currently unregistered without taking
any locks outside the notifier system.  Because the notifier system itself
does not synchronise unregistration with respect to the calling of the
chain, we as its user need to do our own locking.

We are supposed to take the RTNL for all calls to netdev notifiers, so
taking the RTNL should be sufficient to protect it.

The registration path in dev.c already takes the RTNL so it's OK.

7a343d4c46 IPoIB: P_Key change event handling
This patch causes the network interface to respond to P_Key change
events correctly.  As a result, you'll see a child interface in the
"RUNNING" state (netif_carrier_on()) only when the corresponding P_Key
is configured by the SM.  When SM removes a P_Key, the "RUNNING" state
will be disabled for the corresponding network interface.  To
implement this, I added IB_EVENT_PKEY_CHANGE event handling.  To
prevent flushing the device before the device is open by the "delay
open" mechanism, I added an additional device flag called
IPOIB_FLAG_INITIALIZED.

This also prevents the child network interface from trying to join to
multicast groups until the PKEY is configured.  We used to get error
messages like:

    ib0.f2f2: couldn't attach QP to multicast group ff12:401b:f2f2:0:0:0:ffff:ffff

in this case.  To fix this, I just check IPOIB_FLAG_OPER_UP flag in
ipoib_set_mcast_list().

cf368713a3 IB/srp: Use a fake scatterlist for non-SG SCSI commands
Since the SCSI midlayer is moving towards entirely getting rid of
commands with use_sg == 0, we should treat this case as an exception.
Therefore, change the IB SRP initiator to create a fake scatterlist
for these commands with sg_init_one().  This simplifies the flow of
DMA mapping and unmapping, since SRP can just use dma_map_sg() and
dma_unmap_sg() unconditionally, rather than having to choose between
the dma_{map,unmap}_sg() and dma_{map,unmap}_single() variants.
