While refactoring cgroup creation, a5bca2152036 ("cgroup: factor out
cgroup_create() out of cgroup_mkdir()") incorrectly onlined subsystems
before the new cgroup is associated with it kernfs_node. This is fine
for cgroup proper but cgroup_name/path() depend on the associated
kernfs_node and if a subsystem makes the new cgroup_subsys_state
visible, which they're allowed to after onlining, it can lead to NULL
dereference.
The current code performs cgroup creation and subsystem onlining in
cgroup_create() and cgroup_mkdir() makes the cgroup and subsystems
visible afterwards. There's no reason to online the subsystems early
and we can simply drop cgroup_apply_control_enable() call from
cgroup_create() so that the subsystems are onlined and made visible at
the same time.

Commit 025bcc1 performed cleanup work on the 'wacom_pl_irq' function, making
it follow the standards used in the rest of the codebase. The change
unintiontionally allowed the function to send input events from reports
that are not marked as being in prox. This can cause problems as the
report values for X, Y, etc. are not guaranteed to be correct. In
particular, occasionally the tablet will send a report with these values
set to zero. If such a report is received it can caus an unexpected jump
in the XY position.
This patch surrounds more of the processing code with a proximity check,
preventing these zeroed reports from overwriting the current state. To
be safe, only the tool type and ABS_MISC events should be reported when
the pen is marked as being out of prox.

In addition to its USB interface, the second-generation Intuos Pro
includes a Bluetooth radio that offers two pairing interfaces: classic
and low-energy. The classic interface functions just like the earlier
Bluetooth-enabled Intuos4 and Graphire4 tablets, appearing as a HID device
that our driver can work with. The low-energy interface is intented to
be used by userspace applications that make use of its paper-to-digital
capabilities.
Despite the USB interface using Wacom's new vendor-defined HID usages,
the Bluetooth interface provides us with useless black-box "blob"
report descriptors like past devices. We thus have to explicitly add
support for the PIDs and reports used.
These devices pack a /lot/ of information into a single Bluetooth
input report. Each report contains up to seven snapshots of the pen
state, four snapshots of the touch state (of five touches each), pad
state, and battery data. Thankfully this isn't too hard for the driver
to report -- it just takes a fair amount of code to extract!

gcc gets confused about the control flow in ktd2692_parse_dt(), causing

When doing a kernel build with 'make -s', everything is silenced except
the objtool build. That's because the tools tree support for silent
builds is some combination of missing and broken.
Three changes are needed to fix it:
- Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the
tools Makefiles can see it.
- tools/scripts/Makefile.include: fix the tools Makefiles' ability to
recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from
the top-level Makefile. This silences the "DESCEND objtool" message.
- tools/build/Makefile.build: add support to the tools Build files for
recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are
copied from the top-level Makefile. This silences all the object
compile/link messages.

The goal of erratum #27704 workaround was to make sure that ASIDs and VMIDs
are unique across all SMMU instances on affected Cavium systems.
Currently, the workaround code partitions ASIDs and VMIDs by increasing
global cavium_smmu_context_count which in turn becomes the base ASID and VMID
value for the given SMMU instance upon the context bank initialization.
For systems with multiple SMMU instances this approach implies the risk
of crossing 8-bit ASID, like for 1-socket CN88xx capable of 4 SMMUv2,
128 context banks each:
SMMU_0 (0-127 ASID RANGE)
SMMU_1 (127-255 ASID RANGE)
SMMU_2 (256-383 ASID RANGE) <--- crossing 8-bit ASID
SMMU_3 (384-511 ASID RANGE) <--- crossing 8-bit ASID
Since now we use 8-bit ASID (SMMU_CBn_TCR2.AS = 0) we effectively misconfigure
ASID[15:8] bits of SMMU_CBn_TTBRm register for SMMU_2/3. Moreover, we still
assume non-zero ASID[15:8] bits upon context invalidation. In the end,
except SMMU_0/1 devices all other devices under other SMMUs will fail on guest
power off/on. Since we try to invalidate TLB with 16-bit ASID but we actually
have 8-bit zero padded 16-bit entry.
This patch adds 16-bit ASID support for stage-1 AArch64 contexts so that
we use ASIDs consistently for all SMMU instances.

It is the time we have the real 16-bit Stream ID user, which is the
ThunderX. Its IO topology uses 1:1 map for Requester ID to Stream ID
translation for each root complex which allows to get full 16-bit
Stream ID. Firmware assigns bus IDs that are greater than 128 (0x80)
to some buses under PEM (external PCIe interface). Eventually SMMU
drops devices on that buses because their Stream ID is out of range:
pci 0006:90:00.0: stream ID 0x9000 out of range for SMMU (0x7fff)
To fix above issue enable the Extended Stream ID optional feature
when available.

With the introduction of the new iommu_{register/get}_instance()
interface in commit e4f10ffe4c9b ("iommu: Make of_iommu_set/get_ops() DT
agnostic") (based on struct fwnode_handle as look-up token, so firmware
agnostic) to register IOMMU instances with the core IOMMU layer there is
no reason to keep the old OF based interface around any longer.
Convert all the IOMMU drivers (and OF IOMMU core code) that rely on the
of_iommu_{set/get}_ops() to the new kernel interface to register/retrieve
IOMMU instances and remove the of_iommu_{set/get}_ops() remaining glue
code in order to complete the interface rework.

In the current arm-smmu-v3 driver, all smmus that support 2-level
stream tables are being forced to use them. This is suboptimal for
smmus that support fewer stream id bits than would fill in a single

smmus that both support the feature and whose first level table can
possibly contain more than a single entry.

Netfilter fixes for net
The following patchset contains a large batch with Netfilter fixes for
your net tree, they are:
1) Two patches to solve conntrack garbage collector cpu hogging, one to
remove GC_MAX_EVICTS and another to look at the ratio (scanned entries
vs. evicted entries) to make a decision on whether to reduce or not
the scanning interval. From Florian Westphal.
2) Two patches to fix incorrect set element counting if NLM_F_EXCL is
is not set. Moreover, don't decrenent set->nelems from abort patch
if -ENFILE which leaks a spare slot in the set. This includes a
patch to deconstify the set walk callback to update set->ndeact.
3) Two fixes for the fwmark_reflect sysctl feature: Propagate mark to
reply packets both from nf_reject and local stack, from Pau Espin Pedrol.
4) Fix incorrect handling of loopback traffic in rpfilter and nf_tables
fib expression, from Liping Zhang.
5) Fix oops on stateful objects netlink dump, when no filter is specified.
Also from Liping Zhang.
6) Fix a build error if proc is not available in ipt_CLUSTERIP, related
to fix that was applied in the previous batch for net. From Arnd Bergmann.
7) Fix lack of string validation in table, chain, set and stateful
object names in nf_tables, from Liping Zhang. Moreover, restrict
maximum log prefix length to 127 bytes, otherwise explicitly bail
out.
8) Two patches to fix spelling and typos in nf_tables uapi header file
and Kconfig, patches from Alexander Alemayhu and William Breathitt Gray.

In a bmapx call, bmv_count is the total size of the array, including the
zeroth element that userspace uses to supply the search key. The output
array starts at offset 1 so that we can set up the user for the next
invocation. Since we now can split an extent into multiple bmap records
due to shared/unshared status, we have to be careful that we don't
overflow the output array.
In the original patch f86f403794b ("xfs: teach get_bmapx about shared
extents and the CoW fork") I used cur_ext (the output index) to check
for overflows, albeit with an off-by-one error. Since nexleft no longer
describes the number of unfilled slots in the output, we can rip all
that out and use cur_ext for the overflow check directly.
Failure to do this causes heap corruption in bmapx callers such as
xfs_io and xfs_scrub. xfs/328 can reproduce this problem.

"extable.h" so now move over to that and avoid all the extra header
content in module.h that we don't really need to compile this file.
Since the file does have some EXPORT_SYMBOL, we add export.h include.

This file was using module.h for search_exception_table. We've
now separated that content out into its own file "extable.h" so
now move over to that. Unlike most other instances, we can't
delete the module.h include here since the file needs that for
the within_module_init definition.

Once the dependency on PMU driver (for pad retention control) has been
removed, there is no reason to use syscore_ops based suspend/resume.
This patch replaces it with standard platform device pm_ops based solution.

This patch moves pad retention control from S5PV210 machine code to
Exynos pin controller driver. This helps to avoid possible ordering
and logical dependencies between machine and pin control code. Till
now it worked fine only because sys_ops for machine code and pin
controller were called in registration order.

This patch moves pad retention control from PMU driver to Exynos pin
controller driver. This helps to avoid possible ordering and logical
dependencies between machine, PMU and pin control code. Till now it
worked fine only because sys_ops for PMU and pin controller were called
in registration order.
This is also a preparation for adding new features to Exynos pin
controller driver, like runtime power management and suspending
individual pin controllers, which might be a part of some power domain.

Improvements for Exynos PMU driver for v4.11:
Beside basic function of setting proper configuration for low power modes, the
Exynos PMU (Power Management Unit) driver is also a provider of syscon regmap
for its registers. This regmap is essential to many other drivers wanting to
or needing to implement low power mode.
Exynos pinctrl driver, before getting support for Runtime Power Management,
needs access to this syscon regmap. Let's do it in a DT ABI friendly way.

This patch performs dma sync operations on nvme_command
and nvme_completion.
nvme_command is synced
(a) on receiving of the recv queue completion for cpu access.
(b) before posting recv wqe back to rdma adapter for device access.
nvme_completion is synced
(a) on receiving of the recv queue completion of associated
nvme_command for cpu access.
(b) before posting send wqe to rdma adapter for device access.

We only need to call delete_ctrl once, so given that both
keep-alive timeout and any other fatal error can trigger it,
just make sure we only call delete_ctrl once.

No reason for them to be kept around if we are
deleting the subsystem, so instead of passively
wait for the host to disconnect, actively delete
the controllers.
