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.

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':

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().

unsigned long left by PAGE_SHIFT results in a correct address. This

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

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

AMPDU on NICs supported by iwldvm. This feature gives a big boost in

Our hope is that most of the users out there want wifi to surf on

People who want to enable it can do so with the help of a module
parameter."

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.

Merge tag 'batman-adv-fix-for-davem' of git://git.open-mesh.org/linux-merge
Included changes:
- fix soft-interface MTU computation
- fix bogus pointer mangling when parsing the TT-TVLV
container. This bug led to a wrong memory access.
- fix memory leak by properly releasing the VLAN object
after CRC check
- properly check pskb_may_pull() return value
- avoid potential race condition while adding new neighbour
- fix potential memory leak by removing all the references
to the orig_node object in case of initialization failure
- fix the TT CRC computation by ensuring that every node uses
the same byte order when hosts with different endianess are
part of the same network
- fix severe memory leak by freeing skb after a successful
TVLV parsing
- avoid potential double free when orig_node initialization
fails
- fix potential kernel paging error caused by the usage of
the old value of skb->data after skb reallocation

The CP semaphore queue on CIK has a bug that triggers if uncompleted
waits use the same address while a signal is still pending. Work around
this by using different addresses for each sync.

Static checkers complain that probably curly braces were intended here,
but actually it makes more sense to remove the extra tab.

Most laptops seems to have a vblank period of less than
300 and mclk switching works fine. Drop the quirk and
set the default threshold to 200.

Some hardware may not support standard 64x64 cursors. Add
a drm cap to query the cursor size from the kernel. Some examples
include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32).
This allows things like device specific ddxes to remove asics specific
logic and also allows xf86-video-modesetting to work properly with hw
cursors on this hardware. Default to 64 if the driver doesn't specify
a size.

We were already storing the bpc (bits per color) information
in radeon_crtc, so just use that everywhere rather than
calculating it everywhere we use it. This also allows us
to change it in one place if we ever want to override it.
