c3af0980ce01 ("IB: Add devnode methods to cm_class and umad_class")
added devnode methods that set the mode.
However, these methods don't check for a NULL mode, and so we get a

device_get_devnode() with mode == NULL.
Add the missing checks.

AT91: Change nand buswidth logic to match hardware default configuration
The recently modified nand buswitth configuration is not aligned with
board reality: the double footprint on boards is always populated with 8bits
buswidth nand flashes.
So we have to consider that without particular configuration the 8bits
buswidth is selected by default.
Moreover, the previous logic was always using !board_have_nand_8bit(), we
change it to a simpler: board_have_nand_16bit().

We do attempt to perform a try_to_freeze in cifs_reconnect, but the
connection attempt itself seems to be taking longer than 20s to time
out. The connect timeout is governed by the socket send and receive
timeouts, so we can shorten that period by setting those timeouts
before attempting the connect instead of after.
Adam Williamson tested the patch and said that it seems to have fixed
suspending on his laptop when a cifs share is mounted.

xen/pci: Use the INT_SRC_OVR IRQ (instead of GSI) to preset the ACPI SCI IRQ.
In the past we would use the GSI value to preset the ACPI SCI
IRQ which worked great as GSI == IRQ:
ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 low level)
While that is most often seen, there are some oddities:
ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 20 low level)
which means that GSI 20 (or pin 20) is to be overriden for IRQ 9.
Our code that presets the interrupt for ACPI SCI however would
use the GSI 20 instead of IRQ 9 ending up with:
xen: sci override: global_irq=20 trigger=0 polarity=1
xen: registering gsi 20 triggering 0 polarity 1
xen: --> pirq=20 -> irq=20
xen: acpi sci 20
.. snip..
calling acpi_init+0x0/0xbc @ 1
ACPI: SCI (IRQ9) allocation failed
ACPI Exception: AE_NOT_ACQUIRED, Unable to install System Control Interrupt handler (
20110413/evevent-119)
ACPI: Unable to start the ACPI Interpreter
as the ACPI interpreter made a call to 'acpi_gsi_to_irq' which got nine.
It used that value to request an IRQ (request_irq) and since that was not
present it failed.
The fix is to recognize that for interrupts that are overriden (in our
case we only care about the ACPI SCI) we should use the IRQ number
to present the IRQ instead of the using GSI. End result is that we get:
xen: sci override: global_irq=20 trigger=0 polarity=1
xen: registering gsi 20 triggering 0 polarity 1
xen: --> pirq=20 -> irq=9 (gsi=9)
xen: acpi sci 9
which fixes the ACPI interpreter failing on startup.

ahci: change 'masking port_map' printk to KERN_WARNING level
It's not so much an error as a warning about normal Marvell crazines.
So don't use KERN_ERR that ends up spamming the console even in quiet
mode, it's not _that_ critical.
Explained by Jeff:
"Long explanation, it's a mess:
Marvell took standard AHCI, and bastardized it to include a weird mode
whereby PATA devices appear inside the AHCI DMA and interrupt
infrastructure you're familiar with.
So, PATA devices appear via pata_marvell driver, using basic legacy
IDE programming interface. But SATA devices, which might also be
attached to this chip, either work in under-performing mode or
simply don't work at all (e.g. newer 6 Gbps devices or port
multiplier attachments, NCQ, ...)
On the other hand, 'ahci' driver loads and works with the chip's
attached SATA devices quite beautifully, but is completely unable to
drive any attached PATA devices, due to the Marvell-specific
PATA-under-AHCI interface.
The "masking port_map 0x7 -> 0x3" message is the ahci driver "hiding"
the PATA port(s) from itself, making sure it will only drive the SATA
ports it knows how to drive."

netfilter: Fix ip_route_me_harder triggering ip_rt_bug
Avoid creating input routes with ip_route_me_harder.
It does not work for locally generated packets. Instead,
restrict sockets to provide valid saddr for output route (or
unicast saddr for transparent proxy). For other traffic
allow saddr to be unicast or local but if callers forget
to check saddr type use 0 for the output route.
The resulting handling should be:
- REJECT TCP:
- in INPUT we can provide addr_type = RTN_LOCAL but
better allow rejecting traffic delivered with
local route (no IP address => use RTN_UNSPEC to
allow also RTN_UNICAST).
- FORWARD: RTN_UNSPEC => allow RTN_LOCAL/RTN_UNICAST
saddr, add fix to ignore RTN_BROADCAST and RTN_MULTICAST

The failure is as follows:
1. Userspace gets forcewake lock, lock count >=1
2. GPU hang/reset occurs (forcewake bit is reset)
3. count is now incorrect
The failure can only occur when using the forcewake userspace lock.
This has the unfortunate consequence of messing up the driver as well as
userspace, unless userspace closes the debugfs file, the kernel will
never end up waking the GT since the refcount will be > 1.
The solution is to try to recover the correct forcewake state based on
the refcount. There is a period of time where userspace reads/writes may
occur after the reset, before the GT has been forcewaked. The interface
was never designed to be a perfect solution for userspace reads/writes,
and the kernel portion is fixed by this patch.

watchdog: mtx1-wdt: fix GPIO toggling
Commit
e391be76 (MIPS: Alchemy: Clean up GPIO registers and accessors)
changed the way the GPIO was toggled. Prior to this patch, we would
always actively drive the GPIO output to either 0 or 1, this patch
drove the GPIO active to 0, and put the GPIO in tristate to drive it
to 1, unfortunately this does not work, revert back to active driving.
Using a signed variable (gstate) to hold the gpio state and using a bit-
wise operation on it also resulted in toggling value from 1 to -2 since
the variable is signed. This value was then passed on to gpio_direction_
output, which always perform a if (value) ... to set the value to the
gpio, so we were always writing a 1 to this GPIO instead of 1 -> 0 -> 1 ...

md: avoid endless recovery loop when waiting for fail device to complete.
If a device fails in a way that causes pending request to take a while
to complete, md will not be able to immediately remove it from the
array in remove_and_add_spares.
It will then incorrectly look like a spare device and md will try to
recover it even though it is failed.
This leads to a recovery process starting and instantly aborting over
and over again.
We should check if the device is faulty before considering it to be a
spare. This will avoid trying to start a recovery that cannot
proceed.
This bug was introduced in 2.6.26 so that patch is suitable for any
kernel since then.

ipv4: Fix IPsec slowpath fragmentation problem
ip_append_data() builds packets based on the mtu from dst_mtu(rt->dst.path).
On IPsec the effective mtu is lower because we need to add the protocol
headers and trailers later when we do the IPsec transformations. So after
the IPsec transformations the packet might be too big, which leads to a
slowpath fragmentation then. This patch fixes this by building the packets
based on the lower IPsec mtu from dst_mtu(&rt->dst) and adapts the exthdr
handling to this.

added a check to see if we exceed the mtu when we add trailer_len.
However, the mtu is already subtracted by the trailer length when the
xfrm transfomation bundles are set up. So IPsec packets with mtu
size get fragmented, or if the DF bit is set the packets will not
be send even though they match the mtu perfectly fine. This patch

drm/i915: more struct_mutex locking
When auditing the locking in i915_gem.c (for a prospective change which
I then abandoned), I noticed two places where struct_mutex is not held

Since one is in initial setup and the other in driver unload, I'm
guessing the mutex is not required for either; but post a patch in case
it is.

drm/i915: use shmem_truncate_range
The interface to ->truncate_range is changing very slightly: once "tmpfs:

For now there is only a slight inefficiency while this remains unapplied,
but it will soon become essential for managing shmem's use of swap.
Change i915_gem_object_truncate() to use shmem_truncate_range() directly:
which should also spare i915 later change if we switch from
inode_operations->truncate_range to file_operations->fallocate.
