While reviewing an i2c driver for efm32 that needs a similar property
Wolfram Sang pointed out that "location" is a too generic name for
something that is efm32 specific. So add an appropriate namespace and
fall back to the generic name in case of failure.

Pull networking fixes from David Miller:
"I know this is a bit more than you want to see, and I've told the
wireless folks under no uncertain terms that they must severely scale
back the extent of the fixes they are submitting this late in the
game.
Anyways:
1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
is the correct implementation, like it should. Instead it does
something like a NAPI poll operation. This leads to crashes.
From Neil Horman and Arnd Bergmann.
2) Segmentation of SKBs requires proper socket orphaning of the
fragments, otherwise we might access stale state released by the
release callbacks.
This is a 5 patch fix, but the initial patches are giving
variables and such significantly clearer names such that the
actual fix itself at the end looks trivial.
From Michael S. Tsirkin.
3) TCP control block release can deadlock if invoked from a timer on
an already "owned" socket. Fix from Eric Dumazet.
4) In the bridge multicast code, we must validate that the
destination address of general queries is the link local all-nodes
multicast address. From Linus Lüssing.
5) The x86 BPF JIT support for negative offsets puts the parameter
for the helper function call in the wrong register. Fix from
Alexei Starovoitov.
6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
r8169 driver is incorrect. Fix from Hayes Wang.
7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
if a packet is a GSO frame, but that's not the correct test. It
should use skb_is_gso(skb) instead. Fix from Wei Liu.
8) Negative msg->msg_namelen values should generate an error, from
Matthew Leach.
9) at86rf230 can deadlock because it takes the same lock from it's
ISR and it's hard_start_xmit method, without disabling interrupts
in the latter. Fix from Alexander Aring.
10) The FEC driver's restart doesn't perform operations in the correct
order, so promiscuous settings can get lost. Fix from Stefan
Wahren.
11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.
12) Reference count and memory leak fixes in TIPC from Ying Xue and
Erik Hugne.
13) Forced eviction in inet_frag_evictor() must strictly make sure all
frags are deleted, otherwise module unload (f.e. 6lowpan) can
crash. Fix from Florian Westphal.
14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
uses as a hash function), which breaks on PowerPC. From Anton
Blanchard.
The main gist of the issue is that csum_partial() is defined only
as a value that, once folded (f.e. via csum_fold()) produces a
correct 16-bit checksum. It is legitimate, therefore, for
csum_partial() to produce two different 32-bit values over the
same data if their respective alignments are different.
15) Fix endiannes bug in MAC address handling of ibmveth driver, also
from Anton Blanchard.
16) Error checks for ipv6 exthdrs offload registration are reversed,
from Anton Nayshtut.
17) Externally triggered ipv6 addrconf routes should count against the
garbage collection threshold. Fix from Sabrina Dubroca.
18) The PCI shutdown handler added to the bnx2 driver can wedge the
chip if it was not brought up earlier already, which in particular
causes the firmware to shut down the PHY. Fix from Michael Chan.
19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
currently coded it can and does trigger in legitimate situations.
From Eric Dumazet.
20) BNA driver fails to build on ARM because of a too large udelay()
call, fix from Ben Hutchings.
21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
from Eric Dumazet.
22) The vlan passthrough ops added in the previous release causes a
regression in source MAC address setting of outgoing headers in
some circumstances. Fix from Peter Boström"

The compat vDSO is a complicated hack that's needed to maintain
compatibility with a small range of glibc versions.
This removes it and replaces it with a much simpler hack: a config
option to disable the 32-bit vDSO by default.
This also changes the default value of CONFIG_COMPAT_VDSO to n --
users configuring kernels from scratch almost certainly want that
choice.

This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with
an xargs failure to pay attention to error codes). The history lists a

commits is actually present already but not recorded in history due to
git failing. Unfortunately xargs is used in the merge script and it
doesn't do a good job of noticing errors from the commands it invokes.

ASoC: Updates for v3.15
This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with

This commit adds a bare bones driver support for TLV320AIC31XX family
audio codecs. The driver adds basic stereo playback trough headphone
and speaker outputs and mono capture trough microphone inputs.
The driver is currently missing support at least for mini DSP features
and jack detection. I have tested the driver only on TLV320AIC3111,
but based on the data sheets TLV320AIC3100, TLV320AIC3110, and
TLV320AIC3120 should work Ok too.
The base for the implementation was taken from:
git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx

Both QEMU and KVM have already accumulated a significant number of
optimizations based on the hard-coded assumption that ioapic polarity
will always use the ActiveHigh convention, where the logical and
physical states of level-triggered irq lines always match (i.e.,
active(asserted) == high == 1, inactive == low == 0). QEMU guests
are expected to follow directions given via ACPI and configure the
ioapic with polarity 0 (ActiveHigh). However, even when misbehaving
guests (e.g. OS X <= 10.9) set the ioapic polarity to 1 (ActiveLow),
QEMU will still use the ActiveHigh signaling convention when
interfacing with KVM.
This patch modifies KVM to completely ignore ioapic polarity as set by
the guest OS, enabling misbehaving guests to work alongside those which
comply with the ActiveHigh polarity specified by QEMU's ACPI tables.

architecture devices. The timer can be configured as a general-purpose 64-bit
timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
timers, each half can operate in conjunction (chain mode) or independently
(unchained mode) of each other.
It is global timer is a free running up-counter and can generate interrupt
when the counter reaches preset counter values.

Device tree nodes are already treated as objects, and we already want to
expose them to userspace which is done using the /proc filesystem today.
Right now the kernel has to do a lot of work to keep the /proc view in
sync with the in-kernel representation. If device_nodes are switched to
be kobjects then the device tree code can be a whole lot simpler. It
also turns out that switching to using /sysfs from /proc results in
smaller code and data size, and the userspace ABI won't change if
/proc/device-tree symlinks to /sys/firmware/devicetree/base.
v7: Add missing sysfs_bin_attr_init()
v6: Add __of_add_property() early init fixes from Pantelis
v5: Rename firmware/ofw to firmware/devicetree
Fix updating property values in sysfs

the place.
dwc3 got a bit closer towards hibernation support with after
a few patches re-factoring code to be reused for hibernation.
Also in dwc3 two new workarounds for known silicon bugs have
been implemented, some randconfig build errors have been fixed,
and it was taught about the new generic phy layer.
MUSB on AM335x now supports isochronous transfers thanks to
George Cherian's work.
The atmel_usba driver got two crash fixes: one when no endpoint
was specified in DeviceTree data and another when stopping the UDC
in DEBUG builds.
Function FS got a much needed fix to ffs_epfile_io() which was
copying too much data to userspace in some cases.
The printer gadget got a fix for a possible deadlock and plugged
a memory leak.
Ethernet drivers now use NAPI for RX which gives improved throughput.
Other than that, the usual miscelaneous fixes, cleanups, and
the like.

dm-snapshot metadata corruption fix for bug introduced in 3.14-rc1, an
important refcount < 0 fix for the DM persistent data library's space
map metadata interface which fixes corruption reported by a few dm-thinp
users, and last but not least: more extensive fixes than ideal for
dm-thinp's data resize capability (which has had growing pain much like
we've seen from -ENOSPC handling of filesystems that mature). The end
result is dm-thinp now handles metadata operation failure and no data

This set of changes reorganises imx-drm's DT bindings by re-using the OF
graph parsing code which was located in drivers/media, removing the
temporary bindings.
The result is that more TODO entries are now removed. While we're not
quite done with this yet as there's a few straggling updates to imx-ldb
to come, but leaving these out is not detrimental at this point in time
- they are more an enhancement.
However, this pull has the additional complication that we're sharing
seven commits with Mauro's V4L git tree, which move the OF graph parsing
code out of drivers/media into drivers/of. Philipp's imx-drm changes
depend on these and my previously committed round of imx-drm commits.
Hence, the diffstat below is from a test merge with your tree head
(17b02809cf).
Mauro merged those seven commits earlier today as a git pull, so both
trees will be sharing exactly the same commit IDs.
I've given these changes a spin here on both my Hummingboard and Cubox-i4
(one is iMX6Solo, the other is iMX6Quad based), which includes Xorg using
the DRM device directly, and I find nothing wrong.
The diffstat does look a little scarey - this is because we're having to
update the ARM DT files along with this change, and obviously the
dependency on the OF graph parsing code.

This enables support for userspace to fetch and initiate FSP and
Platform dumps from the service processor (via firmware) through sysfs.
Based on original patch from Vasant Hegde <hegdevasant@linux.vnet.ibm.com>
Flow:
- We register for OPAL notification events.
- OPAL sends new dump available notification.
- We make information on dump available via sysfs
- Userspace requests dump contents
- We retrieve the dump via OPAL interface
- User copies the dump data
- userspace sends ack for dump
- We send ACK to OPAL.
sysfs files:
- We add the /sys/firmware/opal/dump directory
- echoing 1 (well, anything, but in future we may support
different dump types) to /sys/firmware/opal/dump/initiate_dump
will initiate a dump.
- Each dump that we've been notified of gets a directory
in /sys/firmware/opal/dump/ with a name of the dump type and ID (in hex,
as this is what's used elsewhere to identify the dump).
- Each dump has files: id, type, dump and acknowledge
dump is binary and is the dump itself.
echoing 'ack' to acknowledge (currently any string will do) will
acknowledge the dump and it will soon after disappear from sysfs.
OPAL APIs:
- opal_dump_init()
- opal_dump_info()
- opal_dump_read()
- opal_dump_ack()
- opal_dump_resend_notification()
Currently we are only ever notified for one dump at a time (until
the user explicitly acks the current dump, then we get a notification
of the next dump), but this kernel code should "just work" when OPAL
starts notifying us of all the dumps present.

Based on a patch by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>
This patch adds support to read error logs from OPAL and export
them to userspace through a sysfs interface.
We export each log entry as a directory in /sys/firmware/opal/elog/
Currently, OPAL will buffer up to 128 error log records, we don't
need to have any knowledge of this limit on the Linux side as that
is actually largely transparent to us.
Each error log entry has the following files: id, type, acknowledge, raw.
Currently we just export the raw binary error log in the 'raw' attribute.
In a future patch, we may parse more of the error log to make it a bit
easier for userspace (e.g. to be able to display a brief summary in
petitboot without having to have a full parser).
If we have >128 logs from OPAL, we'll only be notified of 128 until
userspace starts acknowledging them. This limitation may be lifted in
the future and with this patch, that should "just work" from the linux side.
A userspace daemon should:
- wait for error log entries using normal mechanisms (we announce creation)
- read error log entry
- save error log entry safely to disk
- acknowledge the error log entry
- rinse, repeat.
On the Linux side, we read the error log when we're notified of it. This
possibly isn't ideal as it would be better to only read them on-demand.
However, this doesn't really work with current OPAL interface, so we
read the error log immediately when notified at the moment.
I've tested this pretty extensively and am rather confident that the
linux side of things works rather well. There is currently an issue with
the service processor side of things for >128 error logs though.

The original documentation was very unclear.
The code fix is presumably related to the formerly unclear
documentation: SOCK_TIMESTAMPING_RX_SOFTWARE has no effect on
__sock_recv_timestamp's behavior, so calling __sock_recv_ts_and_drops
from sock_recv_ts_and_drops if only SOCK_TIMESTAMPING_RX_SOFTWARE is
set is pointless. This should have no user-observable effect.

If a thin metadata operation fails the current transaction will abort,
whereby causing potential for IO layers up the stack (e.g. filesystems)
to have data loss. As such, set THIN_METADATA_NEEDS_CHECK_FLAG in the
thin metadata's superblock which:
1) requires the user verify the thin metadata is consistent (e.g. use
thin_check, etc)
2) suggests the user verify the thin data is consistent (e.g. use fsck)
The only way to clear the superblock's THIN_METADATA_NEEDS_CHECK_FLAG is
to run thin_repair.
On metadata operation failure: abort current metadata transaction, set
pool in read-only mode, and now set the needs_check flag.
As part of this change, constraints are introduced or relaxed:
* don't allow a pool to transition to write mode if needs_check is set
* don't allow data or metadata space to be resized if needs_check is set
* if a thin pool's metadata space is exhausted: the kernel will now
force the user to take the pool offline for repair before the kernel
will allow the metadata space to be extended.
Also, update Documentation to include information about when the thin
provisioning target commits metadata, how it handles metadata failures
and running out of space.

This reverts commit 40b367d95f.
Russell King has raised the idea of creating a proper PMU driver for
this SoC that would incorporate the functionality currently in this
driver. It would also cover the use case for the graphics subsystem on
this SoC.
To prevent having to maintain the devicetree ABI for this limited
interrupt-handler driver, we revert the driver before it hits a mainline
tagged release (eg v3.15).

The hysteresis register is shared among both temperature sensors.
This means changing one also affects the other. To avoid confusion,
established way to express this is to make only the first instance writable
and keep all other instances as read-only. Otherwise users may be
confused that changing the second writable value also affects the first,
while it is more obvious that a writable value may affect a different
read-only value.

In commit e2d265d3b5 (canfd: add support for CAN FD in CAN_RAW sockets)
CAN FD frames with a payload length up to 8 byte are passed to legacy
sockets where the CAN FD support was not enabled by the application.
After some discussions with developers at a fair this well meant feature
leads to confusion as no clean switch for CAN / CAN FD is provided to the
application programmer. Additionally a compatibility like this for legacy
CAN_RAW sockets requires some compatibility handling for the sending, e.g.
make CAN2.0 frames a CAN FD frame with BRS at transmission time (?!?).
This will become a mess when people start to develop applications with
real CAN FD hardware. This patch reverts the bad compatibility code
together with the documentation describing the removed feature.

The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This binding
document describes the bindings for both of them since the bindings are very
similar.
Each of them needs:
* A address range where the registers are mapped
* An interrupt number for the device interrupt
* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
clock, for the AXI softmacro it is the AXI bus interface clock.
Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.

Add bindings for TI Async External Memory Interface (AEMIF) controller.
The Async External Memory Interface (EMIF16/AEMIF) controller is intended to
provide a glue-less interface to a variety of asynchronous memory devices like
ASRA M, NOR and NAND memory. A total of 256M bytes of any of these memories
can be accessed via 4 chip selects with 64M byte access per chip select.
We are not encoding CS number in reg property, it's memory partition number.
The CS number is encoded for Davinci NAND node using standalone property
"ti,davinci-chipselect" and we need to provide two memory ranges to it,
as result we can't encode CS number in "reg" for AEMIF child devices
(NAND/NOR/etc), as it will break bindings compatibility.
In this patch, NAND node is used just as an example of child node.

of the peripheral, it should not be part of the genpool controlling the sram.
Therefore add the option to define reserved regions as subnodes of the

Add support for the MSIOF variant in the R-Car H2 (r8a7790) and M2
(r8a7791) SoCs.
Binding documentation:
- Add future-proof "renesas,msiof-<soctype>" compatible values,
- The default for "renesas,rx-fifo-size" is 256 on R-Car H2 and M2,
- "renesas,tx-fifo-size" and "renesas,rx-fifo-size" are deprecated for
soctype-specific bindings,
- Add example bindings.
Implementation:
- MSIOF on R-Car H2 and M2 requires the transmission of dummy data if
data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write
dummy transmission data to SITFDR" in paragraph "Transmit and Receive
Procedures" of the Hardware User's Manual).
- As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR
register (Receive Clock Select Register), and some bits in the RMDR1
(Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2)
registers.
- Use the recently introduced SPI_MASTER_MUST_TX flag to enable support
for dummy transmission in the SPI core, and to differentiate from other
MSIOF implementations in code paths that need this.
- New DT compatible values ("renesas,msiof-r8a7790" and
"renesas,msiof-r8a7791") are added, as well as new platform device
names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof").
- The default RX FIFO size is 256 words on R-Car H2 and M2.
This is loosely based on a set of patches from Takashi Yoshii

Randomize the load address of modules in the kernel to make kASLR
effective for modules. Modules can only be loaded within a particular
range of virtual address space. This patch adds 10 bits of entropy to
the load address by adding 1-1024 * PAGE_SIZE to the beginning range
where modules are loaded.
The single base offset was chosen because randomizing each module
load ends up wasting/fragmenting memory too much. Prior approaches to
minimizing fragmentation while doing randomization tend to result in
worse entropy than just doing a single base address offset.
Example kASLR boot without this change, with a single module loaded:
---[ Modules ]---
0xffffffffc0000000-0xffffffffc0001000 4K ro GLB x pte
0xffffffffc0001000-0xffffffffc0002000 4K ro GLB NX pte
0xffffffffc0002000-0xffffffffc0004000 8K RW GLB NX pte
0xffffffffc0004000-0xffffffffc0200000 2032K pte
0xffffffffc0200000-0xffffffffff000000 1006M pmd
---[ End Modules ]---
Example kASLR boot after this change, same module loaded:
---[ Modules ]---
0xffffffffc0000000-0xffffffffc0200000 2M pmd
0xffffffffc0200000-0xffffffffc03bf000 1788K pte

0xffffffffc03c1000-0xffffffffc03c3000 8K RW GLB NX pte
0xffffffffc03c3000-0xffffffffc0400000 244K pte

Merge tag 'iio-for-3.15b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Second round of IIO new driver, functionality and cleanups for the 3.15 series.
There are a few fixes in here that might, earlier in a cycle, have gone
to Greg as fixes. Given they are either minor or have never actually
been observed as causing trouble (the locking bug in the event code) and
are invasive, I have included them in this pull request, targeting the
3.15 merge window instead.
The rest are pretty uncontroversial new drivers, a handy little tool for
the example code in our documentation and little cleanups.
New drivers
* Freescale Vybrid and i.MX6SLX ADC driver.
* HID Sensor hub proximity sensors.
* HID Sensor hub pressure sensors.
* LPS25H Pressure sensors added to the ST micro pressure sensor driver.
New functionality
* lsiio tool. This is added to the staging tree as we haven't yet moved
the example code it sits with out. Moving this code out is now a reasonably
high priority but holding up this tool in the meantime did not seem
worthwhile.

The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI
controller.
Unfortunately, this SPI controller, even though quite similar, is significantly
different from the recently supported A31 SPI controller (different registers
offset, split/merged registers, etc.). Supporting both controllers in a single
driver would be unreasonable, hence the addition of a new driver.
Like its more recent counterpart, it supports DMA, but the driver only does PIO
until we have a dmaengine driver for this platform.

The new Armada 375 and Armada 38x Marvell SoCs are based on Cortex-A9
CPU cores and use the ARM GIC as their main interrupt controller.
However, for various purposes (wake-up from suspend, MSI interrupts),
they have kept a separate MPIC interrupt controller, acting as a slave
to the GIC. This MPIC was already used as the primary controller on
previous Marvell SoCs, so this commit extends the existing driver to
allow the MPIC to be used as a GIC slave.

Pull PCI updates from Bjorn Helgaas:
"The most interesting thing here is the change to enable INTx (by
clearing PCI_COMMAND_INTX_DISABLE) if the BIOS left INTx disabled.
Apparently the Baytrail BIOS does this, which means EHCI doesn't work.
Also, fix an AHCI MSI regression and other issues with the recent MSI
changes. This also adds pci_enable_msi_exact() and
pci_enable_msix_exact(), which aren't regression fixes, but will keep
us from touching drivers twice (once to stop using the deprecated
pci_enable_msi(), etc., and again to use the *_exact() variants).
There's also a minor MVEBU fix.
