If IPv6 is disabled on boot (ipv6.disable=1), but nft_fib_inet ends up
dealing with a IPv6 packet, it causes a kernel panic in
fib6_node_lookup_1(), crashing in bad_page_fault.
The panic is caused by trying to deference a very low address (0x38
in ppc64le), due to ipv6.fib6_main_tbl = NULL.
BUG: Kernel NULL pointer dereference at 0x00000038
The kernel panic was reproduced in a host that disabled IPv6 on boot and
have to process guest packets (coming from a bridge) using it's ip6tables.
Terminate rule evaluation when packet protocol is IPv6 but the ipv6 module
is not loaded.

Replace the explicit ESSIV handling in the dm-crypt driver with calls
into the crypto API, which now possesses the capability to perform
this processing within the crypto subsystem.
Note that we reorder the AEAD cipher_api string parsing with the TFM
instantiation: this is needed because cipher_api is mangled by the
ESSIV handling, and throws off the parsing of "authenc(" otherwise.

Implement a template that wraps a (skcipher,shash) or (aead,shash) tuple
so that we can consolidate the ESSIV handling in fscrypt and dm-crypt and
move it into the crypto API. This will result in better test coverage, and
will allow future changes to make the bare cipher interface internal to the
crypto subsystem, in order to increase robustness of the API against misuse.

Revised pull request to fix up a missing Signed-off-by and roll in
a fix in the lsm9ds1 support after I broke it when applying.
Revised again because the fix changed a hash meaning a fix
that previously followed it now had the wrong fixes tag.
A few fixes in here that could have gone a faster path but aren't quite
worth the rush for 5.3.
New device support
* ad7606
- Support the ad7606b which adds a software controlled mode alongside
the pin controlled only approach of the ad7606. Including dt-bindings.
* lsm6dsx
- Add support for the gyro and accelerometer part of the lsm9ds1 which is
a compound device also including a magnetometer (st_sensors driver).
Includes bindings and precursor rework of the driver.
Features
* ad7192
- Add support for low pass filter control.
- DT binding docs.
Cleanups and minor fixes
* MAINTAINERS
- Fix a typo in a path.
- Add entry for ad7606
* ad5380
- Fix a failure to dereference a pointer before atempting to assign the
value.
* ad7192
- Drop platform data as not used in mainline and we now have full DT bindings.
* ad7606
- YAML conversion for dt-bindings.
* adis16240
- Rework write_raw to make it more readable using GENMASK.
* adis16460
- Fix and issue with an unsigned variable holding potential negatives.
* cros_ec
- Fix missing default of calibration vector so that we get 'something'
before calibration is complete on a given axis.
* hid-sensors
- Use int_pow instead of opencoding.
* isl29501
- rename dt-binding docs to include renesas inline with other renesas parts
and general current convention.
* kxcjk1013
- Improve comments on the 'unusual' ACPI ids used to identify which sensor
is which in certain laptops.
* lsm6dsx
- Add one bit to the fifo status masks for a number of parts.
- Drop a reserved entry from the sensitivity values to tidy up interface.
- Use core conversion macro from G to m/s^2 for lsm9ds1 to make it easier

* max1027
- Use device managed APIs to avoid manual error handling and cleanup.

If less space is available in the perf ring buffer than the ETR buffer,
barrier packets inserted in the trace stream by tmc_sync_etr_buf() are
skipped over when the head of the buffer is moved forward, resulting in
traces that can't be decoded.
This patch decouples the process of syncing ETR buffers and the addition
of barrier packets in order to perform the latter once the offset in the
trace buffer has been properly computed.

When tracing etm data of multiple threads on multiple cpus through
perf interface, each cpu has a unique etr_perf_buffer while sharing
the same etr device. There is no guarantee that the last cpu starts
etm tracing also stops last. This makes perf_data check fail.
Fix it by checking etr_buf instead of etr_perf_buffer.
Also move the code setting and clearing perf_buf to more suitable
places.

TMC etr always copies all available data to perf aux buffer, which
may exceed the available space in perf aux buffer. It isn't suitable
for not-snapshot mode, because:
1) It may overwrite previously written data.
2) It may make the perf_event_mmap_page->aux_head report having more
or less data than the reality.
So change to only copy the latest data fitting the available space in
perf aux buffer.

Synchronization is recommended before disabling the trace registers
to prevent any start or stop points being speculative at the point
of disabling the unit (section 7.3.77 of ARM IHI 0064D).
Synchronization is also recommended after programming the trace
registers to ensure all updates are committed prior to normal code
resuming (section 4.3.7 of ARM IHI 0064D).
Let's ensure these syncronization points are present in the code
and clearly commented.
Note that we could rely on the barriers in CS_LOCK and
coresight_disclaim_device_unlocked or the context switch to user
space - however coresight may be of use in the kernel.
On armv8 the mb macro is defined as dsb(sy) - Given that the etm4x is
only used on armv8 let's directly use dsb(sy) instead of mb(). This
removes some ambiguity and makes it easier to correlate the code with
the TRM.

Add new parameter (flow_steering_mode) to control the flow steering
mode of the driver.
Two modes are supported:
1. DMFS - Device managed flow steering
2. SMFS - Software/Driver managed flow steering.
In the DMFS mode, the HW steering entities are created through the
FW. In the SMFS mode this entities are created though the driver
directly.
The driver will use the devlink steering mode only if the steering
domain supports it, for now SMFS will manages only the switchdev eswitch
steering domain.
User command examples:
- Set SMFS flow steering mode::
$ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime
- Read device flow steering mode::
$ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
pci/0000:06:00.0:
name flow_steering_mode type driver-specific
values:
cmode runtime value smfs

Rules are the actual objects that tie matchers, header values and
actions. Each rule belongs to a matcher, which can hold multiple rules
sharing the same mask. Each rule is a specific set of values and
actions.
When a packet reaches a matcher it is being matched against the
matcher`s rules. In case of a match over a rule its actions will be
executed. Each rule object contains a set of STEs, where each STE is a
definition of match values and actions defined by the rule.
This file handles the rule operations and processing.
