1ccf6aa19a IB/uverbs: Fix lockdep warning when QP is created with 2 CQs
Lockdep warns when userspace creates a QP that uses different CQs for
send completions and receive completions, because both CQs are locked
and their mutexes belong to the same lock class.  However, we know
that the mutexes are distinct and the nesting is safe (there is no
possibility of AB-BA deadlock because the mutexes are locked with
down_read()), so annotate the situation with SINGLE_DEPTH_NESTING to
get rid of the lockdep warning.

b27075735e IB/mthca: Fix lid used for sending traps
The SM LID used to send traps to is incorrectly set to port LID.  This
is a regression from 2.6.17 -- after a PortInfo MAD is received, no
traps are sent to the SM LID.  The traps go to the loopback interface
instead, and are dropped there.  The SM LID should be taken from the
sm_lid of the PortInfo response.

If the amount of flash is not divisible by 2 then the mask in

187ef15268 [MTD] Unlock NOR flash automatically where necessary
Introduce the MTD_STUPID_LOCK flag which indicates that the flash chip is
always locked after power-up, so all sectors need to be unlocked before it
is usable.

If this flag is set, and the chip provides an unlock() operation,
mtd_add_device will unlock the whole MTD device if it's writeable.  This
means that non-writeable partitions will stay locked.

Set MTD_STUPID_LOCK in fixup_use_atmel_lock() so that these chips will work
as expected.

To prevent the deadlock in dasd_device_from_cdev if it is called

needs to be removed. Let the driver_data of the ccw device point
to the dasd_device structure directly and use the ccw device lock

2dbc2418ba [S390] zcrypt user space interface.
The user space interface of the zcrypt device driver implements the old
user space interface as defined by the old z90crypt driver. Everything
is there, the /dev/z90crypt misc character device, all the lovely ioctls
and the /proc file. Even writing to the z90crypt proc file to configure
the crypto device still works. It stands to reason to remove the proc
write function someday since a much cleaner configuration via the sysfs
is now available.

The ap bus device drivers register crypto cards to the zcrypt user
space interface. The request router of the user space interface
picks one of the registered cards based on the predicted latency
for the request and calls the driver via a callback found in the
zcrypt_ops of the device. The request router only knows which
operations the card can do and the minimum / maximum number of bits
a request can have.

1534c3820c [S390] zcrypt adjunct processor bus.
Add a bus for the adjunct processor interface. Up to 64 devices can
be connect to the ap bus interface, each device with 16 domains. That
makes 1024 message queues. The interface is asynchronous, the answer
to a message sent to a queue needs to be received at some later point
in time. Unfortunately the interface does not provide interrupts when
a message reply is pending. So the ap bus needs to implement some
fancy polling, each active queue is polled once per 1/HZ second or
continuously if an idle cpus exsists and the poll thread is activ
(see poll_thread parameter).

The ap bus uses the sysfs path /sys/bus/ap and has two bus attributes,
ap_domain and config_time. The ap_domain selects one of the 16 domains
to be used for this system. This limits the maximum number of ap devices
to 64. The config_time attribute contains the number of seconds between
two ap bus scans to find new devices.

The ap bus uses the modalias entries of the form "ap:tN" to autoload
the ap driver for hardware type N. Currently known types are:

9359085988 [PATCH] libata: improve handling of diagostic fail (and hardware that misreports it)
Our ATA probe code checks that a device is not reporting a diagnostic
failure during start up. Unfortunately at least one device seems to like
doing this - the Gigabyte iRAM.

This is only done for the master right now (which is fine for the iRAM
as it is SATA), as with PATA some combinations of ATAPI device seem to
fool the check into seeing a drive that isn't there if it is applied to
the slave.

fea63e3801 [PATCH] libata: fix non-uniform ports handling
Non-uniform ports handling got broken while updating libata to handle
those in the same host.  Only separate irq for the non-uniform
secondary port was implemented while all other fields (host flags,
transfer mode...) of the secondary port simply shared those of the
first.

For ata_piix combined mode, which ATM is the only user of non-uniform
ports, this causes the secondary port assume the wrong type.  This can
cause PATA port to use SATA ops, which results in bogus check on PCS
and detection failure.

This patch adds ata_probe_ent->pinfo2 which points to optional
port_info for the secondary port.  For the time being, this seems to
be the simplest solution.  This workaround will be removed together
with ata_probe_ent itself after init model is updated to allow more
flexibility.

When the libata is trying to handle legacy ide ports (0x1f0 for instance), it

The result is that this situation :

  01f0-01f7 : libata

is seen as conflict, which is wrong.

53ccce2395 [PATCH] ehea: bugfix for register access functions
Hi Jeff,

sorry to bother you again. We figured out that the readq function we
included in the eHEA patch we sent yesterday to access eHEA registers
is defined as little endian on POWER. This collides with our adapter.
We talked to some PPC people who told us there is a discussion going
on about new access functions. We were told to use __raw_readq /
__raw_writeq for now.

This patch fixes this bug found by our internal tests today.
Please apply this small patch on the latest patch we sent you yesterday.
If it is easier for you I can also give you the entire eHEA patch again.

sorry and thanks a lot,
Jan-Bernd

72e8d6bbc1 [PATCH] e1000 disable device on PCI error
A recent patch in -mm3 titled
"gregkh-pci-pci-don-t-enable-device-if-already-enabled.patch" causes
pci_enable_device() to be a no-op if the kernel thinks that the device is
already enabled.  This change breaks the PCI error recovery mechanism in
the e1000 device driver, since, after PCI slot reset, the card is no longer
enabled.  This is a trivial fix for this problem.  Tested.

[PATCH 6/9] s390: qeth driver fixes [3/6]

From: Frank Pavlic <fpavlic@de.ibm.com>
       	fixed kernel panic caused by qeth driver:
        Using a bonding device qeth driver will realloc
        headroom for every skb coming from the bond device.
        Once this happens qeth frees the original skb and
        set the skb pointer to the new realloced skb.
        Under heavy transmit workload (e.g.UDP streams) through bond
        network device the qdio output queue might get full.
        In this case we return with EBUSY from qeth_send_packet.
        Returning to qeth_hard_start_xmit routine
        the skb address on the stack still points to the old address,
        which has been freed before.
        Returning from qeth_hard_start_xmit with EBUSY results in
        requeuing the skb. In this case it corrupts the qdisc queue
        and results in kernel panic.

add7afc756 IB/srp: Don't schedule reconnect from srp
If there is a problem in the connection, the SCSI mid-layer will
eventually call srp_reset_host(), which will call srp_reconnect(), so
we do not need to schedule a call to srp_reconnect_work() from
srp_completion().

Removing this prevents srp_reset_host() from failing if a reconnect
scheduled from srp_completion() is already in progress, which in turn
was causing crashes as both SCSI midlayer and srp_reconnect() were
cancelling commands.
