Fix the HSM error_mask mapping.
Changes:
- Better mapping in ac_err_mask()
- In HSM_ST_FIRST ans HSM_ST state, check ATA_ERR|ATA_DF and map it to AC_ERR_DEV instead of AC_ERR_HSM.
- In HSM_ST_FIRST and HSM_ST state, map DRQ=1 ERR=1 to AC_ERR_HSM.
- For PIO data in and DRQ=1 ERR=1, add check after the junk data block is read.

The driver currently keeps local copies of the hardware request/response queue indexes.

[SCTP]: A better solution to fix the race between sctp_peeloff() and
sctp_rcv().
The goal is to hold the ref on the association/endpoint throughout the
state-machine process. We accomplish like this:
/* ref on the assoc/ep is taken during lookup */
if owned_by_user(sk)
sctp_add_backlog(skb, sk);
else
inqueue_push(skb, sk);
/* drop the ref on the assoc/ep */
However, in sctp_add_backlog() we take the ref on assoc/ep and hold it
while the skb is on the backlog queue. This allows us to get rid of the
sock_hold/sock_put in the lookup routines.
Now sctp_backlog_rcv() needs to account for potential association move.
In the unlikely event that association moved, we need to retest if the
new socket is locked by user. If we don't this, we may have two packets
racing up the stack toward the same socket and we can't deal with it.
If the new socket is still locked, we'll just add the skb to its backlog
continuing to hold the ref on the association. This get's rid of the
need to move packets from one backlog to another and it also safe in
case new packets arrive on the same backlog queue.
The last step, is to lock the new socket when we are moving the
association to it. This is needed in case any new packets arrive on
the association when it moved. We want these to go to the backlog since
we would like to avoid the race between this new packet and a packet
that may be sitting on the backlog queue of the old socket toward the
same association.

[ARM] 3529/1: s3c24xx: fix restoring control register with undefined instruction
Patch from Dimitry Andric
In arch/arm/mach-s3c2410/sleep.S, the coprocessor registers are saved at
suspend time, and restored at resume time. However, an undefined
instruction is used when attempting to restore a non-existent "auxiliary
control register". This leads to a crash on S3C2412, which has an ARM926
core instead of an ARM920.
At suspend time, the following fragment runs:
mrc p15, 0, r7, c2, c0, 0 @ translation table base address
mrc p15, 0, r8, c2, c0, 0 @ auxiliary control register
mrc p15, 0, r9, c1, c0, 0 @ control register
and at resume time, the following fragment runs:
mcr p15, 0, r7, c2, c0, 0 @ translation table base
mcr p15, 0, r8, c1, c1, 0 @ auxilliary control
...
mcr p15, 0, r9, c1, c0, 0 @ turn on MMU, etc
There are several problems with these fragments:
1. The ARM920 and ARM926 cores don't have any "auxiliary control
register", at least not according to the ARM920 and ARM926 TRM's.
2. The 2nd line of suspend erroneously saves the c2 register again.
3. This saved c2 value is restored using an undefined instruction. For
some reason this does not crash on ARM920, but does crash on ARM926.
The following patch fixes all these problems.

From: "Angelo P. Castellani" <angelo.castellani+lkml@gmail.com>
Using NewReno, if a sk_buff is timed out and is accounted as lost_out,
it should also be removed from the sacked_out.
This is necessary because recovery using NewReno fast retransmit could
take up to a lot RTTs and the sk_buff RTO can expire without actually
being really lost.
left_out = sacked_out + lost_out
in_flight = packets_out - left_out + retrans_out
Using NewReno without this patch, on very large network losses,
left_out becames bigger than packets_out + retrans_out (!!).

[PATCH] slab: Fix kmem_cache_destroy() on NUMA
With CONFIG_NUMA set, kmem_cache_destroy() may fail and say "Can't
free all objects." The problem is caused by sequences such as the
following (suppose we are on a NUMA machine with two nodes, 0 and 1):
* Allocate an object from cache on node 0.
* Free the object on node 1. The object is put into node 1's alien
array_cache for node 0.
* Call kmem_cache_destroy(), which ultimately ends up in __cache_shrink().
* __cache_shrink() does drain_cpu_caches(), which loops through all nodes.
For each node it drains the shared array_cache and then handles the
alien array_cache for the other node.
However this means that node 0's shared array_cache will be drained,
and then node 1 will move the contents of its alien[0] array_cache
into that same shared array_cache. node 0's shared array_cache is
never looked at again, so the objects left there will appear to be in
use when __cache_shrink() calls __node_shrink() for node 0. So
__node_shrink() will return 1 and kmem_cache_destroy() will fail.
This patch fixes this by having drain_cpu_caches() do
drain_alien_cache() on every node before it does drain_array() on the
nodes' shared array_caches.
The problem was originally reported by Or Gerlitz <ogerlitz@voltaire.com>.

sky2: prevent dual port receiver problems
When both ports are receiving simultaneously, the receive logic gets confused
and may pass up a packet before it is full. This causes hangs, and IP will see
lots of garbage packets. There is even the potential for data corruption if
a later arriving packet DMA's into freed memory.
It looks like a hardware bug because status arrives for a packet but no
data is there. Until this bug is worked out, block the user from bringing
up both ports at once.

The ixp2000 driver for the enp2611 was developed on a board with
three gigabit ports, but some enp2611 models only have two ports
(and only one onboard PM3386.) The current driver assumes there
are always three ports and so it doesn't work on the two-port
version of the board at all.
This patch adds a bit of logic to the enp2611 driver to limit the
number of ports to 2 if the second PM3386 isn't detected.

[PATCH] devices.txt: remove pktcdvd entry
Changing the driver to use dynamic device numbers was one of the many
changes that were made in order to have the driver accepted into the
mainline kernel. Therefore I would say that the entry in devices.txt is
obsolete. This patch removes it.
