Pull ARM updates from Russell King:
"In this ARM merge, we remove more lines than we add. Changes include:
- Enable imprecise aborts early, so that bus errors aren't masked
until later in the boot. This has the side effect that boot
loaders which provoke these aborts can cause the kernel to crash
early in boot, so we install a handler to report this event around
the site where these are enabled.
- Remove the buggy but impossible to enable cmpxchg syscall code.
- Add unwinding annotations to some assembly code.
- Add support for atomic half-word exchange for ARMv6k+.
- Reduce ioremap() alignment for SMP/LPAE cases where we don't need
the large alignment.
- Addition of an "optimal" 3G configuration for systems with 1G of
RAM.
- Increase vmalloc space by 128M.
- Constify some SMP operations structures, which have never been
writable.
- Improve ARMs dma_mmap() support for mapping DMA coherent mappings
into userspace.
- Fix to the NMI backtrace code in the IPI case on ARM where the
failing CPU gets stuck for 10s waiting for its own IPI to be
delivered.
- Removal of legacy PM support from the AMBA bus driver.
- Another fix for the previous fix of vdsomunge"

Now that max_stack_lock is a global variable, it requires a naming
convention that is unlikely to collide. Rename it to the same naming
convention that the other stack_trace variables have.

A stack frame may be used in a different way depending on cpu architecture.
Thus it is not always appropriate to slurp the stack contents, as current
check_stack() does, in order to calcurate a stack index (height) at a given
function call. At least not on arm64.
In addition, there is a possibility that we will mistakenly detect a stale
stack frame which has not been overwritten.
This patch makes check_stack() a weak function so as to later implement
arch-specific version.

For cases where CONFIG_LBDAF is not set. The struct ppa_addr exceeds its

the generic ppa format. We therefore refactor it to u64 and

As pointed out by Nikolay and further explained by Geert, the initial
for_each_netdev_feature macro was broken, as feature would get set outside
of the block of code it was intended to run in, thus only ever working for
the first feature bit in the mask. While less pretty this way, this is
tested and confirmed functional with multiple feature bits set in
NETIF_F_UPPER_DISABLES.

Up to now, a new timeout value is only evaluated against min_timeout
if max_timeout is provided. This does not really make sense; a driver
can have a minimum timeout even if it does not have a maximum timeout.
Ensure that it is not smaller than min_timeout, even if max_timeout
is not set.

behaviour in both the cfg80211 and mac80211 API.
Currently, iwlmvm already implements that behaviour; the other
drivers implementing CQM RSSI events may have to be changed.
This behaviour lets userspace know what the current state is
without relying on querying the data which is racy.

This patch adds device tree support for the netxbig LEDs.
This also introduces a additionnal DT binding for the GPIO extension bus
(netxbig-gpio-ext) used to configure the LEDs. Since this bus could also
be used to control other devices, then it seems more suitable to have it
in a separate DT binding.

There are some netdev features, which when disabled on an upper device,
such as a bonding master or a bridge, must be disabled and cannot be
re-enabled on underlying devices.
This is a rework of an earlier more heavy-handed appraoch, which simply
disables and prevents re-enabling of netdev features listed in a new
define in include/net/netdev_features.h, NETIF_F_UPPER_DISABLES. Any upper
device that disables a flag in that feature mask, the disabling will
propagate down the stack, and any lower device that has any upper device
with one of those flags disabled should not be able to enable said flag.
Initially, only LRO is included for proof of concept, and because this
code effectively does the same thing as dev_disable_lro(), though it will
also activate from the ethtool path, which was one of the goals here.
[root@dell-per730-01 ~]# ethtool -k bond0 |grep large

[root@dell-per730-01 ~]# ethtool -k p5p1 |grep large

dmesg dump:
[ 1033.277986] bond0: Disabling feature 0x0000000000008000 on lower dev p5p2.

This has been successfully tested with bnx2x, qlcnic and netxen network
cards as slaves in a bond interface. Turning LRO on or off on the master
also turns it on or off on each of the slaves, new slaves are added with
LRO in the same state as the master, and LRO can't be toggled on the
slaves.
Also, this should largely remove the need for dev_disable_lro(), and most,
if not all, of its call sites can be replaced by simply making sure
NETIF_F_LRO isn't included in the relevant device's feature flags.
Note that this patch is driven by bug reports from users saying it was
confusing that bonds and slaves had different settings for the same
features, and while it won't be 100% in sync if a lower device doesn't
support a feature like LRO, I think this is a good step in the right
direction.

This work adds support for "persistent" eBPF maps/programs. The term
"persistent" is to be understood that maps/programs have a facility
that lets them survive process termination. This is desired by various
eBPF subsystem users.
Just to name one example: tc classifier/action. Whenever tc parses
the ELF object, extracts and loads maps/progs into the kernel, these
file descriptors will be out of reach after the tc instance exits.
So a subsequent tc invocation won't be able to access/relocate on this
resource, and therefore maps cannot easily be shared, f.e. between the
ingress and egress networking data path.
The current workaround is that Unix domain sockets (UDS) need to be
instrumented in order to pass the created eBPF map/program file
descriptors to a third party management daemon through UDS' socket
passing facility. This makes it a bit complicated to deploy shared
eBPF maps or programs (programs f.e. for tail calls) among various
processes.
We've been brainstorming on how we could tackle this issue and various
approches have been tried out so far, which can be read up further in
the below reference.
The architecture we eventually ended up with is a minimal file system
that can hold map/prog objects. The file system is a per mount namespace
singleton, and the default mount point is /sys/fs/bpf/. Any subsequent
mounts within a given namespace will point to the same instance. The
file system allows for creating a user-defined directory structure.
The objects for maps/progs are created/fetched through bpf(2) with
two new commands (BPF_OBJ_PIN/BPF_OBJ_GET). I.e. a bpf file descriptor
along with a pathname is being passed to bpf(2) that in turn creates
(we call it eBPF object pinning) the file system nodes. Only the pathname
is being passed to bpf(2) for getting a new BPF file descriptor to an
existing node. The user can use that to access maps and progs later on,
through bpf(2). Removal of file system nodes is being managed through
normal VFS functions such as unlink(2), etc. The file system code is
kept to a very minimum and can be further extended later on.
The next step I'm working on is to add dump eBPF map/prog commands
to bpf(2), so that a specification from a given file descriptor can
be retrieved. This can be used by things like CRIU but also applications
can inspect the meta data after calling BPF_OBJ_GET.
Big thanks also to Alexei and Hannes who significantly contributed
in the design discussion that eventually let us end up with this
architecture here.

Add a bpf_map_get() function that we're going to use later on and
align/clean the remaining helpers a bit so that we have them a bit
more consistent:
- __bpf_map_get() and __bpf_prog_get() that both work on the fd
struct, check whether the descriptor is eBPF and return the
pointer to the map/prog stored in the private data.
Also, we can return f.file->private_data directly, the function
signature is enough of a documentation already.
- bpf_map_get() and bpf_prog_get() that both work on u32 user fd,
call their respective __bpf_map_get()/__bpf_prog_get() variants,
and take a reference.

This patch fixes following problems :
1) percpu_counter_init() can return an error, therefore
init_frag_mem_limit() must propagate this error so that
inet_frags_init_net() can do the same up to its callers.
2) If ip[46]_frags_ns_ctl_register() fail, we must unwind
properly and free the percpu_counter.
Without this fix, we leave freed object in percpu_counters
global list (if CONFIG_HOTPLUG_CPU) leading to crashes.

- Support for a few extra operations that need scratch buffers on

- Expanded the feature set of regmap_irq to cope with some extra

Support for message signing was merged into 3.19, along with
nocephx_require_signatures option. But, all that option does is allow
the kernel client to talk to clusters that don't support MSG_AUTH
feature bit. That's pretty useless, given that it's been supported
since bobtail.
Meanwhile, if one disables message signing on the server side with
"cephx sign messages = false", it becomes impossible to use the kernel
client since it expects messages to be signed if MSG_AUTH was
negotiated. Add nocephx_sign_messages option to support this use case.

and open source/open emitter, also know as "single-ended"
configurations.
- Generic request/free operations that handle calling out
to the (optional) pin control backend.
- Some refactoring related to an ABI change that did not
happen, yet provide useful.
- Added a real-time compliance checklist. Many GPIO chips
have irqchips, and need to think this over with the RT
patches going upstream.
- Restructure, fix and clean up Kconfig menus a bit.
New drivers:
- New driver for AMD Promony.
- New driver for ACCES 104-IDIO-16, a port-mapped I/O
card, ISA-style. Very retro.
Subdriver changes:
- OMAP changes to handle real time requirements.
- Handle trigger types for edge and level IRQs on PL061
properly. As this hardware is very common it needs to
set a proper example for others to follow.
- Some container_of() cleanups.
- Delete the unused MSM driver in favor of the driver that
is embedded inside the pin control driver.
- Cleanup of the ath79 GPIO driver used by many, many
OpenWRT router targets.
- A consolidated IT87xx driver replacing the earlier
very specific IT8761e driver.
- Handle the TI TCA9539 in the PCA953x driver. Also
handle ACPI devices in this subdriver.
- Drop xilinx arch dependencies as these FPGAs seem to
profilate over a few different architectures. MIPS and
ARM come to mind.

Merge tag 'gpio-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for the v4.4 development cycle.
The only changes hitting outside drivers/gpio are in the pin control
subsystem and these seem to have settled nicely in linux-next.
Development mistakes and catfights are nicely documented in the
reverts as you can see. The outcome of the ABI fight is that we're
working on a chardev ABI for GPIO now, where hope to show results for
the v4.5 kernel.
Summary of changes:
GPIO core:
- Define and handle flags for open drain/open collector and open
source/open emitter, also know as "single-ended" configurations.
- Generic request/free operations that handle calling out to the
(optional) pin control backend.
- Some refactoring related to an ABI change that did not happen, yet
provide useful.
- Added a real-time compliance checklist. Many GPIO chips have
irqchips, and need to think this over with the RT patches going
upstream.
- Restructure, fix and clean up Kconfig menus a bit.
New drivers:
- New driver for AMD Promony.
- New driver for ACCES 104-IDIO-16, a port-mapped I/O card,
ISA-style. Very retro.
Subdriver changes:
- OMAP changes to handle real time requirements.
- Handle trigger types for edge and level IRQs on PL061 properly. As

v4.4 kernel development cycle:
Infrastructure:
- Doug Anderson wrote a patch adding an "init" state
different from the "default" state for pin control
state handling in the core framework. This is applied
before the driver's probe() call if defined and takes
precedence over "default". If both are defined, "init"
will be applied *before* probe() and "default" will be
applied *after* probe().
Significant subdriver improvements:
- SH PFC is switched to getting GPIO ranges from the
device tree ranges property on DT platforms.
- Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all
modernized.
- Got rid of SH PFC hardcoded IRQ numbers.
- Allwinner sunxi external interrupt through the "r"
controller.
- Moved the Cygnus driver to use DT-provided GPIO
ranges.
New drivers:
- Atmel PIO4 pin controller for the SAMA4D2 family
New subdrivers:
- Rockchip RK3036 subdriver
- Renesas SH PFC R8A7795 subdriver
- Allwinner sunxi A83T PIO subdriver
- Freescale i.MX7d iomux lpsr subdriver
- Marvell Berlin BG4CT subdriver
- SiRF Atlas 7 step B SoC subdriver
- Intel Broxton SoC subdriver
Apart from this, the usual slew if syntactic and semantic
fixes.

Pull pin control updates from Linus Walleij:
"This is the big bulk of pin control changes for the v4.4 kernel
development cycle. Development pace is high in pin control again this
merge window. 28 contributors, 83 patches.
It hits a few sites outside the pin control subsystem:
- Device tree bindings in Documentation (as usual)
- MAINTAINERS
- drivers/base/* for the "init" state handling by Doug Anderson.
This has been ACKed by Greg.
- drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change
in the USB subsystem. This has been ACKed by both Greg and Felipe.
- arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone
through the ARM SoC tree but ended up here.
This time I am using Geert Uytterhoeven as submaintainer for SH PFC
since the are three-four people working in parallel with new Renesas
ASICs.
