KRYO4XX silver/LITTLE CPU cores with revision r1p0 are affected by
erratum 1530923 and 1024718, so add them to the respective list.
The variant and revision bits are implementation defined and are
different from the their Cortex CPU counterparts on which they are
based on, i.e., r1p0 is equivalent to rdpe.

Implement a managed variant of of_mdiobus_register(). We need to make
mdio_devres into its own module because otherwise we'd hit circular
sumbol dependencies between phylib and of_mdio.
Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
We currently have two managed helpers for mdiobus - devm_mdiobus_alloc()
and devm_mdiobus_register(). The idea behind devres is that the release
callback releases whatever resource the devm function allocates. In the
mdiobus case however there's no devres associated with the device by
devm_mdiobus_register(). Instead the release callback for
devm_mdiobus_alloc(): _devm_mdiobus_free() unregisters the device if
it is marked as managed.
This all seems wrong. The managed structure shouldn't need to know or
care about whether it's managed or not - and this is the case now for
struct mii_bus. The devres wrapper should be opaque to the managed
resource.
This changeset makes devm_mdiobus_alloc() and devm_mdiobus_register()
conform to common devres standards: devm_mdiobus_alloc() allocates a
devres structure and registers a callback that will call mdiobus_free().
__devm_mdiobus_register() allocated another devres and registers a
callback that will unregister the bus.

There are two processed schema files:
- processed-schema-examples.yaml
Used for 'make dt_binding_check'. This is always a full schema.
- processed-schema.yaml
Used for 'make dtbs_check'. This may be a full schema, or a smaller
subset if DT_SCHEMA_FILES is given by a user.
If DT_SCHEMA_FILES is not specified, they are the same. You can copy
the former to the latter instead of running dt-mk-schema twice. This
saves the cpu time a lot when you do 'make dt_binding_check dtbs_check'
because building the full schema takes a couple of seconds.
If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated
based on the specified yaml files.

We are having more and more schema files.
Commit 8b6b80218b01 ("dt-bindings: Fix command line length limit
calling dt-mk-schema") fixed the 'Argument list too long' error of
the schema checks, but the same error happens while cleaning too.
'make clean' after 'make dt_binding_check' fails as follows:
$ make dt_binding_check
[ snip ]
$ make clean
make[2]: execvp: /bin/sh: Argument list too long

make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2
make: *** [Makefile:1763: _clean_Documentation] Error 2
'make dt_binding_check' generates so many .example.dts, .dt.yaml files,
which are passed to the 'rm' command when you run 'make clean'.

build artifacts before they are processed by scripts/Makefile.clean

1) Improve hardware layouts and structure for kTLS support
2) Generalize ICOSQ (Internal Channel Operations Send Queue)
Due to the asynchronous nature of adding new kTLS flows and handling
HW asynchronous kTLS resync requests, the XSK ICOSQ was extended to
support generic async operations, such as kTLS add flow and resync, in
addition to the existing XSK usages.
3) kTLS hardware flow steering and classification:
The driver already has the means to classify TCP ipv4/6 flows to send them
to the corresponding RSS HW engine, as reflected in patches 3 through 5,
the series will add a steering layer that will hook to the driver's TCP
classifiers and will match on well known kTLS connection, in case of a
match traffic will be redirected to the kTLS decryption engine, otherwise
traffic will continue flowing normally to the TCP RSS engine.
3) kTLS add flow RX HW offload support
New offload contexts post their static/progress params WQEs
(Work Queue Element) to communicate the newly added kTLS contexts
over the per-channel async ICOSQ.
The Channel/RQ is selected according to the socket's rxq index.
A new TLS-RX workqueue is used to allow asynchronous addition of
steering rules, out of the NAPI context.
It will be also used in a downstream patch in the resync procedure.
Feature is OFF by default. Can be turned on by:
$ ethtool -K <if> tls-hw-rx-offload on
4) Added mlx5 kTLS sw stats and new counters are documented in
Documentation/networking/tls-offload.rst
rx_tls_ctx - number of TLS RX HW offload contexts added to device for
decryption.
rx_tls_ooo - number of RX packets which were part of a TLS stream
but did not arrive in the expected order and triggered the resync
procedure.
rx_tls_del - number of TLS RX HW offload contexts deleted from device
(connection has finished).
rx_tls_err - number of RX packets which were part of a TLS stream
but were not decrypted due to unexpected error in the state machine.
5) Asynchronous RX resync
a. The NIC driver indicates that it would like to resync on some TLS
record within the received packet (P), but the driver does not
know (yet) which of the TLS records within the packet.
At this stage, the NIC driver will query the device to find the exact
TCP sequence for resync (tcpsn), however, the driver does not wait
for the device to provide the response.
b. Eventually, the device responds, and the driver provides the tcpsn
within the resync packet to KTLS. Now, KTLS can check the tcpsn against
any processed TLS records within packet P, and also against any record
that is processed in the future within packet P.
The asynchronous resync path simplifies the device driver, as it can
save bits on the packet completion (32-bit TCP sequence), and pass this
information on an asynchronous command instead.

Merge tag 'mlx5-tls-2020-06-26' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux
Saeed Mahameed says:
====================
mlx5-tls-2020-06-26
1) Improve hardware layouts and structure for kTLS support
2) Generalize ICOSQ (Internal Channel Operations Send Queue)
Due to the asynchronous nature of adding new kTLS flows and handling
HW asynchronous kTLS resync requests, the XSK ICOSQ was extended to
support generic async operations, such as kTLS add flow and resync, in
addition to the existing XSK usages.
3) kTLS hardware flow steering and classification:
The driver already has the means to classify TCP ipv4/6 flows to send them
to the corresponding RSS HW engine, as reflected in patches 3 through 5,
the series will add a steering layer that will hook to the driver's TCP
classifiers and will match on well known kTLS connection, in case of a
match traffic will be redirected to the kTLS decryption engine, otherwise
traffic will continue flowing normally to the TCP RSS engine.
3) kTLS add flow RX HW offload support
New offload contexts post their static/progress params WQEs
(Work Queue Element) to communicate the newly added kTLS contexts
over the per-channel async ICOSQ.
The Channel/RQ is selected according to the socket's rxq index.
A new TLS-RX workqueue is used to allow asynchronous addition of
steering rules, out of the NAPI context.
It will be also used in a downstream patch in the resync procedure.
Feature is OFF by default. Can be turned on by:
$ ethtool -K <if> tls-hw-rx-offload on
4) Added mlx5 kTLS sw stats and new counters are documented in
Documentation/networking/tls-offload.rst
rx_tls_ctx - number of TLS RX HW offload contexts added to device for
decryption.
rx_tls_ooo - number of RX packets which were part of a TLS stream
but did not arrive in the expected order and triggered the resync
procedure.
rx_tls_del - number of TLS RX HW offload contexts deleted from device
(connection has finished).
rx_tls_err - number of RX packets which were part of a TLS stream
but were not decrypted due to unexpected error in the state machine.
5) Asynchronous RX resync
a. The NIC driver indicates that it would like to resync on some TLS
record within the received packet (P), but the driver does not
know (yet) which of the TLS records within the packet.
At this stage, the NIC driver will query the device to find the exact
TCP sequence for resync (tcpsn), however, the driver does not wait
for the device to provide the response.
b. Eventually, the device responds, and the driver provides the tcpsn
within the resync packet to KTLS. Now, KTLS can check the tcpsn against
any processed TLS records within packet P, and also against any record
that is processed in the future within packet P.
The asynchronous resync path simplifies the device driver, as it can
save bits on the packet completion (32-bit TCP sequence), and pass this
information on an asynchronous command instead.

These patches address a number of instrumentation issues that were found after
the x86/entry overhaul. When combined with rcu/urgent and objtool/urgent, these
patches make UBSAN/KASAN/KCSAN happy again.
Part of making this all work is bumping the minimum GCC version for KASAN
builds to gcc-8.3, the reason for this is that the __no_sanitize_address
function attribute is broken in GCC releases before that.
No known GCC version has a working __no_sanitize_undefined, however because the
only noinstr violation that results from this happens when an UB is found, we
treat it like WARN. That is, we allow it to violate the noinstr rules in order
to get the warning out.
