"Items of note:
- evdev users can now limit or mask the kind of events they will
receive. This will allow applications such as power manager or
network manager to only be woken when user presses special keys
such as KEY_POWER or KEY_WIFI and not be bothered with ordinary
key presses coming from keyboard
- support for FocalTech FT6236 touchscreen controller
- support for ROHM BU21023/24 touchscreen controller
- edt-ft5x06 touchscreen driver got a face lift and can now be used
with FT5506

uaccess: reimplement probe_kernel_address() using probe_kernel_read()
probe_kernel_address() is basically the same as the (later added) probe_kernel_read(). The return value on EFAULT is a bit different: probe_kernel_address() returns number-of-bytes-not-copied whereas probe_kernel_read() returns -EFAULT. All callers have been checked, none cared. probe_kernel_read() can be overridden by the architecture whereas probe_kernel_address() cannot. parisc, blackfin and um do this, to insert additional checking. Hence this patch possibly fixes obscure bugs, although there are only two probe_kernel_address() callsites outside arch/. My first attempt involved removing probe_kernel_address() entirely and converting all callsites to use probe_kernel_read() directly, but that got tiresome. This patch shrinks mm/slab_common.o by 218 bytes. For a single probe_kernel_address() callsite.

s390: A bunch of fixes and optimizations for interrupt and time
handling.
PPC: Mostly bug fixes.
ARM: No big features, but many small fixes and prerequisites including:
- a number of fixes for the arch-timer
- introducing proper level-triggered semantics for the arch-timers
- a series of patches to synchronously halt a guest (prerequisite for
IRQ forwarding)
- some tracepoint improvements
- a tweak for the EL2 panic handlers
- some more VGIC cleanups getting rid of redundant state
x86: quite a few changes:
- support for VT-d posted interrupts (i.e. PCI devices can inject
interrupts directly into vCPUs). This introduces a new component (in
virt/lib/) that connects VFIO and KVM together. The same infrastructure
will be used for ARM interrupt forwarding as well.
- more Hyper-V features, though the main one Hyper-V synthetic interrupt
controller will have to wait for 4.5. These will let KVM expose Hyper-V
devices.
- nested virtualization now supports VPID (same as PCID but for vCPUs)
which makes it quite a bit faster
- for future hardware that supports NVDIMM, there is support for clflushopt,
clwb, pcommit
- support for "split irqchip", i.e. LAPIC in kernel + IOAPIC/PIC/PIT in
userspace, which reduces the attack surface of the hypervisor
- obligatory smattering of SMM fixes
- on the guest side, stable scheduler clock support was rewritten to not
require help from the hypervisor.

The majority of the changes are driver updates and new device
support. The core framework is mostly unchanged this time
around, with only a couple patches to expose a clk provider
API and make getting clk parent names from DT more robust.
Driver updates:
- Support for clock controllers found on Broadcom Northstar
SoCs and bcm2835 SoC
- Support for Allwinner audio clocks
- A few cleanup patches for Tegra drivers and support for the
highest DFLL frequencies on Tegra124
- Samsung exynos7 fixes and improvements
- i.Mx SoC updates to add a few missing clocks and keep debug
uart clocks on during kernel intialization
- Some mediatek cleanups and support for more subsystem clocks
- Support for msm8916 gpu/audio clocks and qcom's GDSC power domain
controllers
- A new driver for the Silabs si514 clock chip

Power management and ACPI updates for v4.4-rc1
- ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng).
The most significant change is to allow the AML debugger to be
built into the kernel. On top of that there is an update related
to the NFIT table (the ACPI persistent memory interface)
and a few fixes and cleanups.
- ACPI CPPC2 (Collaborative Processor Performance Control v2)
support along with a cpufreq frontend (Ashwin Chaugule).
This can only be enabled on ARM64 at this point.
- New ACPI infrastructure for the early probing of IRQ chips and
clock sources (Marc Zyngier).
- Support for a new hierarchical properties extension of the ACPI
_DSD (Device Specific Data) device configuration object allowing
the kernel to handle hierarchical properties (provided by the
platform firmware this way) automatically and make them available
to device drivers via the generic device properties interface
(Rafael Wysocki).
- Generic device properties API extension to obtain an index of
certain string value in an array of strings, along the lines of
of_property_match_string(), but working for all of the supported
firmware node types, and support for the "dma-names" device
property based on it (Mika Westerberg).
- ACPI core fix to parse the MADT (Multiple APIC Description Table)
entries in the order expected by platform firmware (and mandated
by the specification) to avoid confusion on systems with more than
255 logical CPUs (Lukasz Anaczkowski).
- Consolidation of the ACPI-based handling of PCI host bridges
on x86 and ia64 (Jiang Liu).
- ACPI core fixes to ensure that the correct IRQ number is used to
represent the SCI (System Control Interrupt) in the cases when
it has been re-mapped (Chen Yu).
- New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede).
- ACPI EC driver fixes (Lv Zheng).
- Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri
Kosina, Rami Rosen, Rasmus Villemoes).
- New mechanism in the PM core allowing drivers to check if the
platform firmware is going to be involved in the upcoming system
suspend or if it has been involved in the suspend the system is
resuming from at the moment (Rafael Wysocki).
This should allow drivers to optimize their suspend/resume
handling in some cases and the changes include a couple of users
of it (the i8042 input driver, PCI PM).
- PCI PM fix to prevent runtime-suspended devices with PME enabled
from being resumed during system suspend even if they aren't
configured to wake up the system from sleep (Rafael Wysocki).
- New mechanism to report the number of a wakeup IRQ that woke up
the system from sleep last time (Alexandra Yates).
- Removal of unused interfaces from the generic power domains
framework and fixes related to latency measurements in that
code (Ulf Hansson, Daniel Lezcano).
- cpufreq core sysfs interface rework to make it handle CPUs that
share performance scaling settings (represented by a common
cpufreq policy object) more symmetrically (Viresh Kumar).
This should help to simplify the CPU offline/online handling among
other things.
- cpufreq core fixes and cleanups (Viresh Kumar).
- intel_pstate fixes related to the Turbo Activation Ratio (TAR)
mechanism on client platforms which causes the turbo P-states
range to vary depending on platform firmware settings (Srinivas
Pandruvada).
- intel_pstate sysfs interface fix (Prarit Bhargava).
- Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes
and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G
Bhat, Luis de Bethencourt).
- cpuidle mvebu driver cleanups (Russell King).
- OPP (Operating Performance Points) framework code reorganization
to make it more maintainable (Viresh Kumar).
- Intel Broxton support for the RAPL (Running Average Power Limits)
power capping driver (Amy Wiles).
- Assorted power management code fixes and cleanups (Dan Carpenter,
Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus
Villemoes).

Pull power management and ACPI updates from Rafael Wysocki:
"Quite a new features are included this time.
First off, the Collaborative Processor Performance Control interface
(version 2) defined by ACPI will now be supported on ARM64 along with
a cpufreq frontend for CPU performance scaling.
Second, ACPI gets a new infrastructure for the early probing of IRQ
chips and clock sources (along the lines of the existing similar
mechanism for DT).
Next, the ACPI core and the generic device properties API will now
support a recently introduced hierarchical properties extension of the
_DSD (Device Specific Data) ACPI device configuration object. If the
ACPI platform firmware uses that extension to organize device
properties in a hierarchical way, the kernel will automatically handle
it and make those properties available to device drivers via the
generic device properties API.
It also will be possible to build the ACPICA's AML interpreter
debugger into the kernel now and use that to diagnose AML-related
problems more efficiently. In the future, this should make it
possible to single-step AML execution and do similar things.
Interesting stuff, although somewhat experimental at this point.
Finally, the PM core gets a new mechanism that can be used by device
drivers to distinguish between suspend-to-RAM (based on platform
firmware support) and suspend-to-idle (or other variants of system
suspend the platform firmware is not involved in) and possibly
optimize their device suspend/resume handling accordingly.
In addition to that, some existing features are re-organized quite
substantially.
First, the ACPI-based handling of PCI host bridges on x86 and ia64 is
unified and the common code goes into the ACPI core (so as to reduce
code duplication and eliminate non-essential differences between the
two architectures in that area).
Second, the Operating Performance Points (OPP) framework is
reorganized to make the code easier to find and follow.
Next, the cpufreq core's sysfs interface is reorganized to get rid of
the "primary CPU" concept for configurations in which the same
performance scaling settings are shared between multiple CPUs.
Finally, some interfaces that aren't necessary any more are dropped
from the generic power domains framework.
On top of the above we have some minor extensions, cleanups and bug
fixes in multiple places, as usual.
Specifics:
- ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng).
The most significant change is to allow the AML debugger to be
built into the kernel. On top of that there is an update related

"The main changes in this cycle were:
- More gradual enhancements to atomic ops: new atomic*_read_ctrl()
ops, synchronize atomic_{read,set}() ordering requirements between
architectures, add atomic_long_t bitops. (Peter Zijlstra)
- Add _{relaxed|acquire|release}() variants for inc/dec atomics and
use them in various locking primitives: mutex, rtmutex, mcs, rwsem.
This enables weakly ordered architectures (such as arm64) to make
use of more locking related optimizations. (Davidlohr Bueso)
- Implement atomic[64]_{inc,dec}_relaxed() on ARM. (Will Deacon)
- Futex kernel data cache footprint micro-optimization. (Rasmus

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"

ARM/PCI: Replace pci_sys_data->align_resource with global function pointer
dw_pcie_host_init() creates the PCI host bridge with pci_common_init_dev(), an ARM-specific function that supplies the ARM-specific pci_sys_data structure as the PCI "sysdata". To use dw_pcie_host_init() on other architectures, we will copy the internals of pci_common_init_dev() into pcie-designware.c instead of calling it, and dw_pcie_host_init() will supply the DesignWare pcie_port structure as "sysdata". Most ARM "sysdata" users are specific to non-DesignWare host bridges; they'll be unaffected because those bridges will continue to have the ARM pci_sys_data. Most of the rest are ARM-generic functions called by pci_common_init_dev(); these will be unaffected because dw_pcie_host_init() will no longer call pci_common_init(). But the ARM pcibios_align_resource() can be called by the PCI core for any bridge, so it can't depend on sysdata since it may be either pci_sys_data or pcie_port. Remove the pcibios_align_resource() dependency on sysdata by replacing the pci_sys_data->align_resource pointer with a global function pointer. This is less general (we can no longer have per-host bridge align_resource() methods), but the pci_sys_data->align_resource pointer was used only by Marvell (see mvebu_pcie_enable()), so this would only be a problem if we had a system with a combination of Marvell and other host bridges [bhelgaas: changelog] Signed-off-by: Gabriele Paoloni <gabriele.paoloni@huawei.com> Signed-off-by: Zhou Wang <wangzhou1@hisilicon.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Pratyush Anand <pratyush.anand@gmail.com> |

This is the big bulk of pin control changes for the
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.

Merge tag 'pinctrl-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
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.

ARM: SoC fixes for v4.3
This should be our final batch of fixes for 4.3:
- A patch from Sudeep Holla that fixes annotation of wakeup sources properly,
old unused format seems to have spread through copying.
- Two patches from Tony for OMAP. One dealing with MUSB setup problems due to
runtime PM being enabled too early on the parent device. The other fixes
IRQ numbering for OMAP1.

arm: add missing of_node_put
for_each_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. The of_node_put is duplicated in front of each error return, because the function contains a later error return that is beyond the end of the for_each_child_of_node and thus doesn't need of_node_put. The semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; iterator name for_each_child_of_node; @@ for_each_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | + of_node_put(child); ? return ...; ) ... } @@ expression root,e; local idexpression child; @@ for_each_child_of_node(root, child) { ... when != of_node_put(child) when != e = child + of_node_put(child); ? break; ... } ... when != child // </smpl> Additionally, concatenated a string in an affected line to avoid introducing a checkpatch warning.

xen/arm: Enable cpu_hotplug.c
Build cpu_hotplug for ARM and ARM64 guests. Rename arch_(un)register_cpu to xen_(un)register_cpu and provide an empty implementation on ARM and ARM64. On x86 just call arch_(un)register_cpu as we are already doing. Initialize cpu_hotplug on ARM.

xen/swiotlb: Add support for 64KB page granularity
Swiotlb is used on ARM64 to support DMA on platform where devices are not protected by an SMMU. Furthermore it's only enabled for DOM0. While Xen is always using 4KB page granularity in the stage-2 page table, Linux ARM64 may either use 4KB or 64KB. This means that a Linux page can be spanned accross multiple Xen page. The Swiotlb code has to validate that the buffer used for DMA is physically contiguous in the memory. As a Linux page can't be shared between local memory and foreign page by design (the balloon code always removing entirely a Linux page), the changes in the code are very minimal because we only need to check the first Xen PFN. Note that it may be possible to optimize the function check_page_physically_contiguous to avoid looping over every Xen PFN for local memory. Although I will let this optimization for a follow-up.

xen/swiotlb: Pass addresses rather than frame numbers to xen_arch_need_swiotlb
With 64KB page granularity support, the frame number will be different. It will be easier to modify the behavior in a single place rather than in each caller.

arm/xen: Add support for 64KB page granularity
The hypercall interface is always using 4KB page granularity. This is requiring to use xen page definition macro when we deal with hypercall. Note that pfn_to_gfn is working with a Xen pfn (i.e 4KB). We may want to rename pfn_gfn to make this explicit. We also allocate a 64KB page for the shared page even though only the first 4KB is used. I don't think this is really important for now as it helps to have the pointer 4KB aligned (XENMEM_add_to_physmap is taking a Xen PFN).

xen/grant-table: Make it running on 64KB granularity
The Xen interface is using 4KB page granularity. This means that each
grant is 4KB.
The current implementation allocates a Linux page per grant. On Linux
using 64KB page granularity, only the first 4KB of the page will be
used.
We could decrease the memory wasted by sharing the page with multiple
grant. It will require some care with the {Set,Clear}ForeignPage macro.
Note that no changes has been made in the x86 code because both Linux
and Xen will only use 4KB page granularity.
