This patch introduces a means for syscalls matched in seccomp to notify
some other task that a particular filter has been triggered.
The motivation for this is primarily for use with containers. For example,
if a container does an init_module(), we obviously don't want to load this
untrusted code, which may be compiled for the wrong version of the kernel
anyway. Instead, we could parse the module image, figure out which module
the container is trying to load and load it on the host.
As another example, containers cannot mount() in general since various
filesystems assume a trusted image. However, if an orchestrator knows that
e.g. a particular block device has not been exposed to a container for
writing, it want to allow the container to mount that block device (that
is, handle the mount for it).
This patch adds functionality that is already possible via at least two
other means that I know about, both of which involve ptrace(): first, one
could ptrace attach, and then iterate through syscalls via PTRACE_SYSCALL.
Unfortunately this is slow, so a faster version would be to install a
filter that does SECCOMP_RET_TRACE, which triggers a PTRACE_EVENT_SECCOMP.
Since ptrace allows only one tracer, if the container runtime is that
tracer, users inside the container (or outside) trying to debug it will not
be able to use ptrace, which is annoying. It also means that older
distributions based on Upstart cannot boot inside containers using ptrace,
since upstart itself uses ptrace to monitor services while starting.
The actual implementation of this is fairly small, although getting the
synchronization right was/is slightly complex.
Finally, it's worth noting that the classic seccomp TOCTOU of reading
memory data from the task still applies here, but can be avoided with
careful design of the userspace handler: if the userspace handler reads all
of the task memory that is necessary before applying its security policy,
the tracee's subsequent memory edits will not be read by the tracer.

Pull IOMMU updates from Joerg Roedel:
- Page table code for AMD IOMMU now supports large pages where smaller
page-sizes were mapped before. VFIO had to work around that in the
past and I included a patch to remove it (acked by Alex Williamson)
- Patches to unmodularize a couple of IOMMU drivers that would never
work as modules anyway.
- Work to unify the the iommu-related pointers in 'struct device' into
one pointer. This work is not finished yet, but will probably be in
the next cycle.
- NUMA aware allocation in iommu-dma code
- Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver
- Scalable mode support for the Intel VT-d driver
- PM runtime improvements for the ARM-SMMU driver
- Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom

The Intel vt-d spec rev3.0 introduces a new translation
mode called scalable mode, which enables PASID-granular
translations for first level, second level, nested and
pass-through modes. At the same time, the previous
Extended Context (ECS) mode is deprecated (no production
ever implements ECS).
This patch adds enumeration for Scalable Mode and removes
the deprecated ECS enumeration. It provides a boot time
option to disable scalable mode even hardware claims to
support it.

This patch for the DesignWare AHB Central
Direct Memory Access Controller adds the dma
protection control property:
"snps,dma-protection-control"
as well as the properties specific values defines into
a new include file: include/dt-bindings/dma/dw-dmac.h
Note: The protection control signals are one-to-one
mapped to the AHB HPROT[1:3] signals for this controller.
The HPROT0 (Data Access) is always hardwired to 1.

NXP i.MX8QXP is an ARMv8 SoC with a Cortex-M4 core inside as
system controller, the system controller is in charge of system
power, clock and secure RTC etc. management, Linux kernel
has to communicate with system controller via MU (message unit)
IPC to do RTC operation, this patch adds binding doc for i.MX
system controller RTC driver.

The pcf85263 RTC is compatible with the pcf85363 RTC.
The difference between the pcf85263 and pcf85363 RTC is that the latter has
64 bytes more RAM. This renders them incompatible from a DT point of view.

Experiments showed that on at least the H3/H5/A64 the RTC's internal
oscillator also feeds the CPUS mux in the PRCM.
Export this clock through the device tree, instead of having to use
a dummy fixed-clock device node, for the PRCM to consume. This will
properly describe the relationship between the clocks.

The A31 does not have an external clock output directly from the RTC.
Instead, it has four muxable clock outputs: three (A, B, C) are
controlled from the CCU, and the last (D) is controlled from the PRCM.
Deprecate the usage of the external clock output for the A31 compatible.

While doing Bluetooth enablement for various boards based on various
Allwinner SoCs, minor differences in the RTC modules were found. These
include a lack of an external clock output (A31), different internal
oscillator frequencies (H3/H5/A64/V3/V3s), different regulator voltage
settings (H5/H6), and the presence of miscellaneous registers unrelated
to the RTC (A64/R40/H5/H6). The datasheet also describes different number
of registers for non-volatile storage, though based on actual experiments
the actual number is the same across the board.
This patch adds a list of all pre-H6 variants, grouped by the internal
oscillator's clock rate, regulator settings, and the presence of the
external clock output. Combinations are introduced for the variants that
have miscellaneous registers.
The RTC block in the H6 also handles the 24 MHz DCXO. This will require
more device tree binding changes and will be done later.

The clock output section for this binding describes the two outputs in
the descriptions for both the #clock-cells and clock-output-names
properties.
Instead of overlapping information that is hard to read, rewrite the
clock outputs as a list of indices and descriptions. The properies
can reference this list instead. This will also make it easier to
add notes or conditions to the clocks, and also for adding new outputs.

Pull pin control updates from Linus Walleij:
"We have no core changes but lots of incremental development in drivers
all over the place: Renesas, NXP, Mediatek and Actions Semiconductor
keep churning out new SoCs.
I have some subtree maintainers for Renesas and Intel helping out to
keep down the load, it's been working smoothly (Samsung also have a
subtree but it was not used this cycle.)
New drivers:
- NXP (ex Freescale) i.MX 8 QXP SoC driver.
- Mediatek MT6797 SoC driver.
- Mediatek MT7629 SoC driver.
- Actions Semiconductor S700 SoC driver.
- Renesas RZ/A2 SoC driver.
- Allwinner sunxi suniv F1C100 SoC driver.
- Qualcomm PMS405 PMIC driver.
- Microsemi Ocelot Jaguar2 SoC driver.
Improvements:
- Some RT improvements (using raw spinlocks where appropriate).
- A lot of new pin sets on the Renesas PFC pin controllers.
- GPIO hogs now work on the Qualcomm SPMI/SSBI pin controller GPIO
chips, and Xway.
- Major modernization of the Intel pin control drivers.
- STM32 pin control driver will now synchronize usage of pins with
another CPU using a hardware spinlock"

As pointed by Rob, CRU is a kind of block that can't be guaranteed to
have everything exposed as subnodes. It's a set of various registers
that aren't tied to any single device. It could be described much more
accurately as MFD (Multi-Function Device).
Some hardware blocks may indeed want to access a register or two of the
CRU which requires describing it as the "syscon".
While at it replace exmple node name with the standard "pinctrl" (also
pointed out by Rob).
