Another release, another set of regulator updates. Not much of it is
showing up in the code yet but there's been a lot of discussion going on
about how to enhance the regulator API to work better with modern SoCs
which have a microcontroller sitting between Linux and the hardware.
I'm hopeful that'll start to come through into mainline for v4.2 but
it's not quite there for v4.1 - what we do have (along with the usual
small updates is) is:
- Work from Bjorn Andersson on refactoring the configuration of
regulator loading interfaces to be useful for use with
microcontrollers, the existing interfaces were never actually useful
for anything as-is since nobody was willing to put enough data into
public code.
- A summary tree display in debugfs from Heiko Stübner.
- Support for act6000 regulators.

By their nature many of these changes are risky - we tried to test
them well on many different x86 systems (there are no known

This patch changes the syscall handler to doom (tabort) active
transactions when a syscall is made and return immediately without
performing the syscall.
Currently, the system call instruction automatically suspends an
active transaction which causes side effects to persist when an active
transaction fails.
This does change the kernel's behaviour, but in a way that was
documented as unsupported. It doesn't reduce functionality because
syscalls will still be performed after tsuspend. It also provides a
consistent interface and makes the behaviour of user code
substantially the same across powerpc and platforms that do not
support suspended transactions (e.g. x86 and s390).
Performance measurements using
http://ozlabs.org/~anton/junkcode/null_syscall.c
indicate the cost of a system call increases by about 0.5%.

Having a board where the I2C bus locks up occasionally made it clear
that the bus recovery in the i2c-davinci driver will only work on
some boards, because on regular boards, this will only toggle GPIO
lines that aren't muxed to the actual pins.
The I2C controller on SoCs like da850 (and da830), Keystone 2 has the
built-in capability to bit-bang its lines by using the ICPFUNC registers
of the i2c controller.
Implement the suggested procedure by toggling SCL and checking SDA using
the ICPFUNC registers of the I2C controller when present. Allow platforms
to indicate the presence of the ICPFUNC registers with a has_pfunc platform
data flag and add optional DT property "ti,has-pfunc" to indicate
the same in DT.

This patch updates the binding information to reflect the
extra dt options which are now supported by the sdhci-st.c
driver which enable support for stih407 family silicon.
STiH410 SoC and later support UHS modes for eMMC, so the
driver now makes use of these common bindings. Examples
are provided for both eMMC (which has additional bindings)
and also sd slot for STiH407.

Merge tag 'irqchip-core-4.0' of git://git.infradead.org/users/jcooper/linux into irq/core
irqchip core changes for v4.0 from Jason Cooper
- ST
- New driver, irq-st
- Renesas
- Use u32 type for 32bit regs
This is the NFC pull request for 4.1.
This is a shorter one than usual, as the Intel Field Peak NFC
driver could not make it in time.
We have:
- A new driver for NXP NCI based chipsets, like e.g. the NPC100 or
the PN7150. It currently only supports an i2c physical layer, but
could easily be extended to work on top of e.g. SPI.
This driver also includes support for user space triggered firmware
updates.
- A few minor st21nfc[ab] fixes, cleanups, and comments improvements.
- A pn533 error return fix.
- A few NFC related logs formatting cleanups.

When the CONTINUE bit is set, the interrupt status we are polling to
identify if a transaction has finished can be sporadic. Even though
the transfer has finished, the interrupt status may erroneously
indicate that there is still data in the FIFO. This behaviour causes
random timeouts in large PIO transfers.
Instead of using the CONTINUE bit to control the CS lines, use the SPI
core's CS GPIO handling. Also, now that the CONTINUE bit is not being
used, we can poll for the ALLDONE interrupt to indicate transfer
completion.

Pull networking fixes from David Miller:
1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
previously SACK'd, from Neal Cardwell.
2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
from Cong WANG.
3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
from Cong WANG.
4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.
5) When we encapsulate for a tunnel device, skb->sk still points to the
user socket. So this leads to cases where we retraverse the
ipv4/ipv6 output path with skb->sk being of some other address
family (f.e. AF_PACKET). This can cause things to crash since the
ipv4 output path is dereferencing an AF_PACKET socket as if it were
an ipv4 one.
The short term fix for 'net' and -stable is to elide these socket
checks once we've entered an encapsulation sequence by testing
xmit_recursion.
Longer term we have a better solution wherein we pass the tunnel's
socket down through the output paths, but that is way too invasive
for 'net' and -stable.
From Hannes Frederic Sowa.
6) l2tp_init() failure path forgets to unregister per-net ops, from
Cong WANG.

According to description in 'include/net/dsa.h', in cascade switches
configurations where there are more than one interconnected devices,
'rtable' array in 'dsa_chip_data' structure is used to indicate which
port on this switch should be used to send packets to that are destined
for corresponding switch.
However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
of the _target_ switch, but not current one.
This commit removes redundant devicetree parsing and adds needed port
number as a function argument. So dsa_of_setup_routing_table() now just
looks for target switch number by parsing parent of 'link' device node.
To remove possible misunderstandings with the way of determining target
switch number, a corresponding comment was added to the source code and
to the DSA device tree bindings documentation file.
This was tested on a custom board with two Marvell 88E6095 switches with
following corresponding routing tables: { -1, 10 } and { 8, -1 }.

Documentation: DT bindings: Tegra AHB: require the legacy base address for existing chips
Per Stephen Warren, note in the Tegra AHB DT binding documentation
that we specifically deprecate any attempt to use the IP block's
actual hardware base address, and advocate the use of the legacy
"off-by-four" address in the 'regs' property, for Tegra chips with
existing upstream Linux DT files that include a Tegra AHB node. This
patch updates the documentation accordingly.
Changing the existing kernel DT data isn't under consideration because
Linux kernel DT data policy is to preserve compatibility between newer
DT data files and older kernels. However, this additional step of
changing the documentation should discourage others from sending
kernel patches to try to change the legacy kernel DT data.
Furthermore, for out-of-tree software (such as bootloaders or other
operating systems) that may rely on Linux kernel DT binding
documentation as an ABI (but not the Linux kernel DT data itself),
such a change may allow future convergence with the Linux kernel DT
data without additional code changes.

The CAN_RAW socket can set multiple CAN identifier specific filters that lead
to multiple filters in the af_can.c filter processing. These filters are
indenpendent from each other which leads to logical OR'ed filters when applied.
This socket option joines the given CAN filters in the way that only CAN frames
are passed to user space that matched *all* given CAN filters. The semantic for
the applied filters is therefore changed to a logical AND.
This is useful especially when the filterset is a combination of filters where
the CAN_INV_FILTER flag is set in order to notch single CAN IDs or CAN ID
ranges from the incoming traffic.
As the raw_rcv() function is executed from NET_RX softirq the introduced
variables are implemented as per-CPU variables to avoid extensive locking at
CAN frame reception time.

This allows an accelerometer device to e.g. have an ABS_WHEEL.
It is not permitted to mix normal directional axes and accelerometer axes on
the same device node.

This patch adds support to migrate vcpu interrupts. Two new vcpu ioctls
are added which get/set the complete status of pending interrupts in one
go. The ioctls are marked as available with the new capability
KVM_CAP_S390_IRQ_STATE.
We can not use a ONEREG, as the number of pending local interrupts is not
constant and depends on the number of CPUs.
To retrieve the interrupt state we add an ioctl KVM_S390_GET_IRQ_STATE.
Its input parameter is a pointer to a struct kvm_s390_irq_state which
has a buffer and length. For all currently pending interrupts, we copy
a struct kvm_s390_irq into the buffer and pass it to userspace.
To store interrupt state into a buffer provided by userspace, we add an
ioctl KVM_S390_SET_IRQ_STATE. It passes a struct kvm_s390_irq_state into
the kernel and injects all interrupts contained in the buffer.
