[SCSI] hpsa: poll controller to detect device change event

For shared SAS configurations, hosts need to poll Smart Arrays
periodically in order to be able to detect configuration changes
such as logical drives being added or removed from remote hosts.
A register on the controller indicates when such events have
occurred, and the driver polls the register via a workqueue
and kicks off a rescan of devices if such an event is detected.
Additionally, changes to logical drive raid offload eligibility
are autodetected in this way.

When commands sent down the "fast path" fail, they must be re-tried down the

[SCSI] pm80xx: Spinlock fix

spin_lock_irqsave for the HBA lock is called in one function where flag
is local to that function. Another function is called from the first
function where lock has to be released using spin_unlock_irqrestore for
calling task_done of libsas. In the second function also flag is declared
and used. For calling task_done there is no need to enable the irq. So
instead of using spin_lock_irqsave and spin_unlock_irqrestore, spin_lock
and spin_unlock is used now. This also avoids passing the flags across all
the functions where HBA lock is being used. Also removed redundant code.

[SCSI] hpsa: fixup MSI-X registration

Commit 254f796b9f22b1944c64caabc356a56caaa2facd updated
the driver to use 16 MSI-X vectors, despite the fact that
older controllers would provide only 4.
This was causing MSI-X registration to drop down to INTx
mode. But as the controller support performant mode, the
initialisation will become confused and cause the machine
to stall during boot.

This patch fixes up the MSI-X registration to re-issue
the pci_enable_msix() call with the correct number of
MSI-X vectors. With that the hpsa driver continues to

[SCSI] isci: fix needless ata reset escalations

isci is needlessly tying libata's hands by returning
SAM_STAT_CHECK_CONDITION to some ata errors.  Instead, prefer
SAS_PROTO_RESPONSE to let libata (via sas_ata_task_done()) disposition
the device-to-host fis.

For example isci is triggering an HSM Violation where AHCI is showing a
simple media error for the same bus condition:

isci:
ata7.00: failed command: READ VERIFY SECTOR(S)
ata7.00: cmd 40/00:01:00:00:00/00:00:00:00:00/e0 tag 0
         res 01/04:00:00:00:00/00:00:00:00:00/e0 Emask 0x3 (HSM violation)

ahci:
ata6.00: failed command: READ VERIFY SECTOR(S)
ata6.00: cmd 40/00:01:00:00:00/00:00:00:00:00/e0 tag 0
         res 51/40:01:00:00:00/00:00:00:00:00/e0 Emask 0x9 (media error)

Note that the isci response matches this from sas_ata_task_done():
/* We saw a SAS error. Send a vague error. */
[..]
dev->sata_dev.fis[3] = 0x04; /* status err */
dev->sata_dev.fis[2] = ATA_ERR;

The end effect is that isci is needlessly triggering hard resets when
they are not necessary.

[SCSI] libsas: introduce scmd_dbg() to quiet false positive "timeout" messages

libsas sometimes short circuits timeouts to force commands into error
recovery.  It is misleading to log that the command timed-out in
sas_scsi_timed_out() when in fact it was just queued for error handling.
It's also redundant in the case of a true timeout as libata eh will
detect and report timeouts via it's AC_ERR_TIMEOUT facility.

Given that some environments consider "timeout" errors to be indicative
of impending device failure demote the sas_scsi_timed_out() timeout
message to be disabled by default.  This parallels ata_scsi_timed_out().

[SCSI] bnx2fc: Fixed scsi_remove_target soft lockup when rmmod bnx2x

The problem has been identified to be a change in the scsi_remove_device
path where a call to the pm_runtime_set_memalloc_noio was added when
del_gendisk is called in this path.  Note that the new pm routine
attempts to cycle through all parent devices from the FC target device
to set the memalloc_noio flag.  Because of this new change, a dependency
was created between the FC target device and the parent netdev device
in the destroy path.

In order to synchronized the destroy paths, bnx2fc has been modified
to flush all destroy workqueues in the NETDEV_UNREGISTER return path.

[SCSI] isci: correct erroneous for_each_isci_host macro

In the first place, the loop 'for' in the macro 'for_each_isci_host'
(drivers/scsi/isci/host.h:314) is incorrect, because it accesses
the 3rd element of 2 element array. After the 2nd iteration it executes
the instruction:
        ihost = to_pci_info(pdev)->hosts[2]
(while the size of the 'hosts' array equals 2) and reads an
out of range element.

In the second place, this loop is incorrectly optimized by GCC v4.8
(see http://marc.info/?l=linux-kernel&m=138998871911336&w=2).
As a result, on platforms with two SCU controllers,
the loop is executed more times than it can be (for i=0,1 and 2).
It causes kernel panic during entering the S3 state
and the following oops after 'rmmod isci':

[SCSI] isci: fix reset timeout handling

Remove an erroneous BUG_ON() in the case of a hard reset timeout.  The
reset timeout handler puts the port into the "awaiting link-up" state.
The timeout causes the device to be disconnected and we need to be in
the awaiting link-up state to re-connect the port.  The BUG_ON() made
the incorrect assumption that resets never timeout and we always
complete the reset in the "resetting" state.

Testing this patch also uncovered that libata continues to attempt to
reset the port long after the driver has torn down the context.  Once
the driver has committed to abandoning the link it must indicate to
libata that recovery ends by returning -ENODEV from
->lldd_I_T_nexus_reset().

  is not the case with C: the integer promotion happens at assignment

MAINTAINERS: add entry for the PHY library

The PHY library has been subject to some changes, new drivers and DT
interactions over the past few months. Add myself as a maintainer for
the core PHY library parts and drivers. Make sure the PHY library entry
also covers the Device Tree files which have a close interaction with
the MDIO bus, PHY connection and Ethernet PHY mode parsing.

of_mdio: fix phy interrupt passing

The of_mdiobus_register_phy() is not setting phy->irq thus causing
some drivers to incorrectly assume that the PHY does not have an
IRQ associated with it. Not only do some drivers report no IRQ
they do not install an interrupt handler for the PHY.

Simplify the code setting irq and set the phy->irq at the same
time so that we cover the following issues, which should cover
all the cases the code will find:

- Set phy->irq if node has irq property and mdio->irq is NULL
- Set phy->irq if node has no irq and mdio->irq is not NULL
- Leave phy->irq as PHY_POLL default if none of the above

This fixes the issue:
 net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI

to the correct:
 net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI

net: ethernet: update dependency and help text of mvneta

With the introduction of the support for Armada 375 and Armada 38x,
the hidden Kconfig option MACH_ARMADA_370_XP is being renamed to
MACH_MVEBU_V7. Therefore, the dependency that was used for the mvneta
driver can no longer work. This commit replaces this dependency by a
dependency on PLAT_ORION, which is used similarly for the mv643xx_eth
driver.

In addition to this, it takes this opportunity to adjust the
description and help text to indicate that the driver can is also used
for Armada 38x. Note that Armada 375 cannot use this driver as it has
a completely different networking unit, which will require a separate
driver.

====================
Please pull this batch of fixes intended for the 3.14 stream...

For the iwlwifi one, Emmanuel says:

"As explicitly written in the commit message, we prefer to disable Tx
AMPDU on NICs supported by iwldvm. This feature gives a big boost in
Tx performance, but the firmware is buggy and we can't rely on it.
Our hope is that most of the users out there want wifi to surf on
the web which means that they care more for Rx traffic than for Tx.
People who want to enable it can do so with the help of a module
parameter."

On top of that...

Dan Carpenter fixes a typo/thinko in ath5k.

Olivier Langlois fixes a couple of rtlwifi issues, one which leaves
IRQs disabled too long (causing a variety of problems elsewhere),
and one which fixes an incorrect return code when failing to enable
the NIC.

Russell King fixes a NULL pointer dereference in hostap.

Stanislaw Gruszka fixes a DMA coherence issue in the rtl8187 driver.

net: sctp: fix sctp_connectx abi for ia32 emulation/compat mode

SCTP's sctp_connectx() abi breaks for 64bit kernels compiled with 32bit
emulation (e.g. ia32 emulation or x86_x32). Due to internal usage of
'struct sctp_getaddrs_old' which includes a struct sockaddr pointer,
sizeof(param) check will always fail in kernel as the structure in
64bit kernel space is 4bytes larger than for user binaries compiled
in 32bit mode. Thus, applications making use of sctp_connectx() won't
be able to run under such circumstances.

Introduce a compat interface in the kernel to deal with such
situations by using a 'struct compat_sctp_getaddrs_old' structure
where user data is copied into it, and then sucessively transformed
into a 'struct sctp_getaddrs_old' structure with the help of
compat_ptr(). That fixes sctp_connectx() abi without any changes
needed in user space, and lets the SCTP test suite pass when compiled
in 32bit and run on 64bit kernels.
