Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dmaengine changes from Vinod Koul:
"This brings for slave dmaengine:
- Change dma notification flag to DMA_COMPLETE from DMA_SUCCESS as
dmaengine can only transfer and not verify validaty of dma
transfers
- Bunch of fixes across drivers:
- cppi41 driver fixes from Daniel
- 8 channel freescale dma engine support and updated bindings from
Hongbo
- msx-dma fixes and cleanup by Markus
- DMAengine updates from Dan:
- Bartlomiej and Dan finalized a rework of the dma address unmap
implementation.
- In the course of testing 1/ a collection of enhancements to
dmatest fell out. Notably basic performance statistics, and
fixed / enhanced test control through new module parameters
'run', 'wait', 'noverify', and 'verbose'. Thanks to Andriy and
Linus [Walleij] for their review.
- Testing the raid related corner cases of 1/ triggered bugs in
the recently added 16-source operation support in the ioatdma
driver.
- Some minor fixes / cleanups to mv_xor and ioatdma"

"Following up on last week's discussion, here's my part of the EDAC
pile, highlights in the signed tag.
The last two patches have a date from just now because I've just
applied them to the tree after Johannes sent them to me earlier. I
decided to forward them now because they're trivial.
There's a third one for MPC85xx which adds PCIe error interrupt
support but since it is not so trivial and hasn't seen any linux-next
time, I'm deferring it to 3.14

watchdog: sirf: add watchdog driver of CSR SiRFprimaII and SiRFatlasVI
On CSR SiRFprimaII and SiRFatlasVI, the 6th timer can act as a watchdog timer when the Watchdog mode is enabled. watchdog occur when TIMER watchdog counter matches the value software pre-set, when this event occurs, the effect is the same as the system software reset.

ARM: SoC fixes for 3.13 merge window
A first set of batches of fixes for 3.13. The diffstat is large mostly
because we're adding a defconfig for a family that's been lacking it, and
there's some missing clock information added for i.MX and OMAP.
The at91 new code is around dealing with RTC/RTT reset at boot to fix possible
hangs due to pending wakeup interrupts coming in during early boot.

ARM: OMAP2+: omap_device: maintain sane runtime pm status around suspend/resume
OMAP device hooks around suspend|resume_noirq ensures that hwmod devices are forced to idle using omap_device_idle/enable as part of the last stage of suspend activity. For a device such as i2c who uses autosuspend, it is possible to enter the suspend path with dev->power.runtime_status = RPM_ACTIVE. As part of the suspend flow, the generic runtime logic would increment it's dev->power.disable_depth to 1. This should prevent further pm_runtime_get_sync from succeeding once the runtime_status has been set to RPM_SUSPENDED. Now, as part of the suspend_noirq handler in omap_device, we force the following: if the device status is !suspended, we force the device to idle using omap_device_idle (clocks are cut etc..). This ensures that from a hardware perspective, the device is "suspended". However, runtime_status is left to be active. *if* an operation is attempted after this point to pm_runtime_get_sync, runtime framework depends on runtime_status to indicate accurately the device status, and since it sees it to be ACTIVE, it assumes the module is functional and returns a non-error value. As a result the user will see pm_runtime_get succeed, however a register access will crash due to the lack of clocks. To prevent this from happening, we should ensure that runtime_status exactly indicates the device status. As a result of this change any further calls to pm_runtime_get* would return -EACCES (since disable_depth is 1). On resume, we restore the clocks and runtime status exactly as we suspended with. These operations are not expected to fail as we update the states after the core runtime framework has suspended itself and restore before the core runtime framework has resumed.

ARM: at91: fix hanged boot due to early rtt-interrupt
Make sure the RTT-interrupts are masked at boot by adding a new helper function to be used at SOC-init. This fixes hanged boot on all AT91 SOCs with an RTT, for example, if an RTT-alarm goes off after a non-clean shutdown (e.g. when using RTC wakeup). The RTC and RTT-peripherals are powered by backup power (VDDBU) (on all AT91 SOCs but RM9200) and are not reset on wake-up, user, watchdog or software reset. This means that their interrupts may be enabled during early boot if, for example, they where not disabled during a previous shutdown (e.g. due to a buggy driver or a non-clean shutdown such as a user reset). Furthermore, an RTC or RTT-alarm may also be active. The RTC and RTT-interrupts use the shared system-interrupt line, which is also used by the PIT, and if an interrupt occurs before a handler (e.g. RTC-driver) has been installed this leads to the system interrupt being disabled and prevents the system from booting. Note that when boot hangs due to an early RTC or RTT-interrupt, the only way to get the system to start again is to remove the backup power (e.g. battery) or to disable the interrupt manually from the bootloader. In particular, a user reset is not sufficient. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: stable@vger.kernel.org # 3.11.x |

side: the HV and emulation flavors can now coexist in a single kernel is probably the most interesting change from a user point of view. On the x86 side there are nested virtualization improvements and a few bugfixes. ARM got transparent huge page support, improved overcommit, and support for big endian guests. Finally, there is a new interface to connect KVM with VFIO. This helps with devices that use NoSnoop PCI transactions, letting the driver in the guest execute WBINVD instructions.

Pull Xen updates from Konrad Rzeszutek Wilk:
"This has tons of fixes and two major features which are concentrated
around the Xen SWIOTLB library.
The short <blurb> is that the tracing facility (just one function) has
been added to SWIOTLB to make it easier to track I/O progress.
Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver
"is used to translate physical to machine and machine to physical
addresses of foreign[guest] pages for DMA operations" (Stefano) when
booting under hardware without proper IOMMU.
There are also bug-fixes, cleanups, compile warning fixes, etc.
The commit times for some of the commits is a bit fresh - that is b/c
we wanted to make sure we have the Ack's from the ARM folks - which
with the string of back-to-back conferences took a bit of time. Rest
assured - the code has been stewing in #linux-next for some time.

ARM: tegra: init fuse before setting reset handler
CPU reset handler was set before fuse is initialized, but tegra_cpu_reset_handler_enable() uses tegra_chip_id, which is set by tegra_init_fuse(). This patch reorders the calls so the CPU reset handler code does not read an uninitialized variable.

ARM: vt8500: add defconfig for v6/v7 chips
Add a single-vendor config for vt8500. We can't enable WM8750 in multi_v7_defconfig since it's a v6-based device, but it's still valuable to have an in-tree defconfig that is suitable for the hardware. This is based on multi_v7_defconfig and can be tweaked over time. It gets us off the ground for now. Naming it vt8500_v6_v7 similar to i.MX since there are v5-based vt8500 chips as well.

fbdev changes for 3.13
Nothing particularly stands out in this pull request. The biggest part of the changes are cleanups. Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential dead lock" which hopefully fixes the fb locking issues reported by multiple persons. There are also a few commits that have changes to arch/arm/mach-at91 and arch/avr32, which have been acked by the maintainers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJSg2oCAAoJEPo9qoy8lh71vXsP/2AjkzOlcKBPutMG/W30QMHT tkKfr/RL8C3oXcimkE6ch3ksbFj2t5corxa/DLTdESdTpeFAgxj72pcdhN3X4+Xs 7IokExM2W5s6p4pP66PTr2A5XhEyAHtEMp+2JbHPRzwZitblzBLZvuPUJljwJDpj Z9+sD00xv/MZrXDCsEN8k2xdJ3rFn6JgX267y1qajlsocZoseTF2ed94IN/YnIM7 B2hra1B4E21FPYLzRDOJRmZa0YGomLTymezPnPg33hLBhnJU/aG4HLDHKUZWhduz /6UwACH63ja7I2z/8AZHQ1ACdbGheRtHbjwV9LLYlbaAvPmUqNTZ4b6UeQOb/EZ0 3SPCYbwD6+RMhSx/j/XhySvw82RY0i1aTlTDyjgOggfrfdi4x1Wk54bUWp5l9O3D SX1vSpNLGSh4GKXRzJjf3jouG/LcOzlpDlVZXzgsPzkyirluUv6QdMTopJwFwIGx rFgtsbkvhEsFvaNhhVIqQXKfwZ69r42U5JC+fDM5u7VX0mqyJ1usUNGvNSeifcDg EwUAI6RGnOXCO6crj2BZYpRTdc61tnY9b4CGLHDCeQkEXokEsEJ7Mz+8YfSwFo7X wqh+dAPQaixeHtUFZ8GhHXeAsjoQRSBXygf3NSNmCeP3WsmuozbauuujSrrTHITp LOXFPhU9uxHu4mDd6wrq =59+j -----END PGP SIGNATURE----- Merge tag 'fbdev-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux Pull fbdev changes from Tomi Valkeinen: "Nothing particularly stands out in this pull request.

MTD merge for 3.13
* Unify some compile-time differences so that we have fewer uses of
#ifdef CONFIG_OF in atmel_nand
* Other general cleanups (removing unused functions, options, variables,
fields; use correct interfaces)
* Fix BUG() for new odd-sized NAND, which report non-power-of-2 dimensions via
ONFI
* Miscellaneous driver fixes (SPI NOR flash; BCM47xx NAND flash; etc.)
* Improve differentiation between SLC and MLC NAND -- this clarifies an ABI
issue regarding the MTD "type" (in sysfs and in ioctl(MEMGETINFO)), where
the MTD_MLCNANDFLASH type was present but inconsistently used
* Extend GPMI NAND to support multi-chip-select NAND for some platforms
* Many improvements to the OMAP2/3 NAND driver, including an expanded DT
binding to bring us closer to mainline support for some OMAP systems
* Fix a deadlock in the error path of the Atmel NAND driver probe
* Correct the error codes from MTD mmap() to conform to POSIX and the Linux
Programmer's Manual. This is an acknowledged change in the MTD ABI, but I
can't imagine somebody relying on the non-standard -ENOSYS error code
specifically. Am I just being unimaginative? :)

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"Included in this series are:
1. BE8 (modern big endian) changes for ARM from Ben Dooks
2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.
There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.
The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.
Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"
I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences. Any errors are likely mine. Let's
see how the crypto issues work out..

Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King:
"This series cleans up the handling of DMA masks in a lot of drivers,
fixing some bugs as we go.
Some of the more serious errors include:
- drivers which only set their coherent DMA mask if the attempt to
set the streaming mask fails.
- drivers which test for a NULL dma mask pointer, and then set the
dma mask pointer to a location in their module .data section -
which will cause problems if the module is reloaded.
To counter these, I have introduced two helper functions:
- dma_set_mask_and_coherent() takes care of setting both the
streaming and coherent masks at the same time, with the correct
error handling as specified by the API.
- dma_coerce_mask_and_coherent() which resolves the problem of
drivers forcefully setting DMA masks. This is more a marker for
future work to further clean these locations up - the code which
creates the devices really should be initialising these, but to fix
that in one go along with this change could potentially be very
disruptive.
The last thing this series does is prise away some of Linux's addition
to "DMA addresses are physical addresses and RAM always starts at
zero". We have ARM LPAE systems where all system memory is above 4GB
physical, hence having DMA masks interpreted by (eg) the block layers
as describing physical addresses in the range 0..DMAMASK fails on
these platforms. Santosh Shilimkar addresses this in this series; the
patches were copied to the appropriate people multiple times but were
ignored.
Fixing this also gets rid of some ARM weirdness in the setup of the
max*pfn variables, and brings ARM into line with every other Linux
architecture as far as those go"

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller:
1) The addition of nftables. No longer will we need protocol aware
firewall filtering modules, it can all live in userspace.
At the core of nftables is a, for lack of a better term, virtual
machine that executes byte codes to inspect packet or metadata
(arriving interface index, etc.) and make verdict decisions.
Besides support for loading packet contents and comparing them, the
interpreter supports lookups in various datastructures as
fundamental operations. For example sets are supports, and
therefore one could create a set of whitelist IP address entries
which have ACCEPT verdicts attached to them, and use the appropriate
byte codes to do such lookups.
Since the interpreted code is composed in userspace, userspace can
do things like optimize things before giving it to the kernel.
Another major improvement is the capability of atomically updating
portions of the ruleset. In the existing netfilter implementation,
one has to update the entire rule set in order to make a change and
this is very expensive.
Userspace tools exist to create nftables rules using existing
netfilter rule sets, but both kernel implementations will need to
co-exist for quite some time as we transition from the old to the
new stuff.
Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have
worked so hard on this.
2) Daniel Borkmann and Hannes Frederic Sowa made several improvements
to our pseudo-random number generator, mostly used for things like
UDP port randomization and netfitler, amongst other things.
In particular the taus88 generater is updated to taus113, and test
cases are added.
3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet
and Yang Yingliang.
4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin
Sujir.
5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet,
Neal Cardwell, and Yuchung Cheng.
6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary
control message data, much like other socket option attributes.
From Francesco Fusco.
7) Allow applications to specify a cap on the rate computed
automatically by the kernel for pacing flows, via a new
SO_MAX_PACING_RATE socket option. From Eric Dumazet.
8) Make the initial autotuned send buffer sizing in TCP more closely
reflect actual needs, from Eric Dumazet.
9) Currently early socket demux only happens for TCP sockets, but we
can do it for connected UDP sockets too. Implementation from Shawn
Bohrer.
10) Refactor inet socket demux with the goal of improving hash demux
performance for listening sockets. With the main goals being able
to use RCU lookups on even request sockets, and eliminating the
listening lock contention. From Eric Dumazet.
11) The bonding layer has many demuxes in it's fast path, and an RCU
conversion was started back in 3.11, several changes here extend the
RCU usage to even more locations. From Ding Tianhong and Wang
Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav
Falico.
12) Allow stackability of segmentation offloads to, in particular, allow
segmentation offloading over tunnels. From Eric Dumazet.
13) Significantly improve the handling of secret keys we input into the
various hash functions in the inet hashtables, TCP fast open, as
well as syncookies. From Hannes Frederic Sowa. The key fundamental
operation is "net_get_random_once()" which uses static keys.
Hannes even extended this to ipv4/ipv6 fragmentation handling and
our generic flow dissector.
14) The generic driver layer takes care now to set the driver data to
NULL on device removal, so it's no longer necessary for drivers to
explicitly set it to NULL any more. Many drivers have been cleaned
up in this way, from Jingoo Han.
15) Add a BPF based packet scheduler classifier, from Daniel Borkmann.
16) Improve CRC32 interfaces and generic SKB checksum iterators so that
SCTP's checksumming can more cleanly be handled. Also from Daniel
Borkmann.
17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces
using the interface MTU value. This helps avoid PMTU attacks,
particularly on DNS servers. From Hannes Frederic Sowa.
18) Use generic XPS for transmit queue steering rather than internal
(re-)implementation in virtio-net. From Jason Wang.

GPIO bulk changes for the v3.13 development cycle
- Merged the GPIO descriptor API from Alexandre Courbot.
This is a first step toward trying to get rid of the
global GPIO numberspace for the future.
- Add an API so that driver can flag that a certain GPIO
line is being used by a irqchip backend for generating
IRQs, so that we can enforce checks, like not allowing
users to switch that line to an output at runtime, since
this makes no sense. Implemented corresponding calls
in a few select drivers.
- ACPI GPIO cleanups, refactorings and switch to using the
descriptor-based interface.
- Support for the TPS80036 Palmas GPIO variant.
- A new driver for the Broadcom Kona GPIO SoC IP block.
- Device tree support for the PCF857x driver.
- A set of ARM GPIO refactorings with the goal of getting
rid of a bunch of custom GPIO implementations from the
arch/arm/* tree:
- Move the IOP GPIO driver to the GPIO subsystem and
fix all users to use the gpiolib API for accessing
GPIOs. Delete the old custom GPIO implementation.
- Delete the unused custom PXA GPIO implemention.
- Convert all users of the IXP4 custom GPIO
implementation to use gpiolib and delete the custom
implementation.
- Delete the custom Gemini GPIO implementation, also
completely unused.
- Various cleanups and renamings.
