Commit 3c783b83bd ("net: dsa: mv88e6xxx: get rid of SPEED_MAX setting")
stopped relying on SPEED_MAX constant and hardcoded speed settings
for the switch ports and rely on phylink configuration.
It turned out, however, that when the relevant code is called,
the mac_capabilites of CPU/DSA port remain unset.
mv88e6xxx_setup_port() is called via mv88e6xxx_setup() in
dsa_tree_setup_switches(), which precedes setting the caps in
phylink_get_caps down in the chain of dsa_tree_setup_ports().
As a result the mac_capabilites are 0 and the default speed for CPU/DSA
port is 10M at the start. To fix that, execute mv88e6xxx_get_caps()
and obtain the capabilities driectly.

The S25HL-T/S25HS-T family is the Infineon SEMPER Flash with Quad SPI.
These Infineon chips support volatile version of configuration registers
and it is recommended to update volatile registers in the field application
due to a risk of the non-volatile registers corruption by power interrupt.
Add support for volatile QE bit.
For the single-die package parts (512Mb and 1Gb), only bottom 4KB and
uniform sector sizes are supported. This is due to missing or incorrect
entries in SMPT. Fixup for other sector sizes configurations will be
followed up as needed.

We need to track the flash's internal address mode as there are flashes
that can operate with 4B opcodes but unfortunately do not have a 4B opcode
correspondent for all the 3B opcodes. Such an example is the Infineon
Semper chips which provide 4B opcodes for read/program/erase but do not
provide 4B opcodes for Read/Write Any Register. These registers are
indexed by address and require the internal address mode of the flash
before Read/Write Any Register opcodes are issued.
4B opcodes are preferred over changing the flash's address mode to 4byte,
as set_4byte_addr_mode could be done in a non-volatile way and could break
the boot sequence. Thus we need to track the flash's internal address mode
so that we can use 4B opcodes together with opcodes that don't have a 4B
opcode correspondent. Track flash's internal address mode.
addr_mode_nbytes is discovered when parsing BFPT. For the
BFPT_DWORD1_ADDRESS_BYTES_3_OR_4 case, one could introduce a method that
queries the flash's internal address mode at run-time (works for Winbond).
If a run-time querying can not be accomplished or if SFDP is not defined
at all, but the address mode is volatile and resets to a default known
value at boot, one can change the default addr_mode_nbytes value of 3 by
introducing a flash_info flag. If the address mode can not be queried,
discovered and it is configured via a non-volatile register, we may
introduce a dt property, but it will harm the generic approach of the
jedec,spi-nor compatible. All this complexity is not needed now, so let it
for future development.

At the SFDP parsing time we should not change members of struct spi_nor,
but instead fill members of struct spi_nor_flash_parameters which could
later on be used by callers. The caller will then decide if SFDP params
should be used and more importantly when they should be used. Clean the
code flow and don't initialize nor->addr_nbytes at SFDP parsing time.

A NULL pointer dereference was reported by Wei Chen:

This happens when calling sctp_sendmsg without connecting to server first.
In this case, a data chunk already queues up in send queue of client side
when processing the INIT_ACK from server in sctp_process_init() where it
calls sctp_stream_init() to alloc stream_in. If it fails to alloc stream_in
all stream_out will be freed in sctp_stream_init's err path. Then in the
asoc freeing it will crash when dequeuing this data chunk as stream_out
is missing.
As we can't free stream out before dequeuing all data from send queue, and
this patch is to fix it by moving the err path stream_out/in freeing in
sctp_stream_init() to sctp_stream_free() which is eventually called when
freeing the asoc in sctp_association_free(). This fix also makes the code
in sctp_process_init() more clear.
Note that in sctp_association_init() when it fails in sctp_stream_init(),
sctp_association_free() will not be called, and in that case it should
go to 'stream_free' err path to free stream instead of 'fail_init'.

Sending a PTP packet can imply to use the normal TX driver datapath but
invoked from the driver's ptp worker. The kernel generic TX code
disables softirqs and preemption before calling specific driver TX code,
but the ptp worker does not. Although current ptp driver functionality
does not require it, there are several reasons for doing so:
1) The invoked code is always executed with softirqs disabled for non
PTP packets.
2) Better if a ptp packet transmission is not interrupted by softirq
handling which could lead to high latencies.
3) netdev_xmit_more used by the TX code requires preemption to be
disabled.
Indeed a solution for dealing with kernel preemption state based on static
kernel configuration is not possible since the introduction of dynamic
preemption level configuration at boot time using the static calls
functionality.

Merge series from Douglas Anderson <dianders@chromium.org>:
The main goal of this series is to make a small dent in cleaning up
the way we deal with regulator loads. The idea is to add some extra
functionality to the regulator "bulk" API so that consumers can
specify the load using that.
The use of kmap_atomic() is being deprecated in favor of kmap_local_page().
With kmap_local_page(), the mappings are per thread, CPU local and not
globally visible. Furthermore, the mappings can be acquired from any
context (including interrupts).
Therefore, replace kmap_atomic() with kmap_local_page() in
copy_string_kernel(). Instead of open-coding local mapping + memcpy(),
use memcpy_to_page(). Delete a redundant call to flush_dcache_page().
Tested with xfstests on a QEMU/ KVM x86_32 VM, 6GB RAM, booting a kernel
with HIGHMEM64GB enabled.

internally with file systems reporting less space available from df when
we had failed background relocations.

====================
This v14 patch set introduces the Elastic RDMA Adapter (ERDMA) driver,
which released in Apsara Conference 2021 by Alibaba. The PR of ERDMA
userspace provider has already been created [1].
ERDMA enables large-scale RDMA acceleration capability in Alibaba ECS
environment, initially offered in g7re instance. It can improve the
efficiency of large-scale distributed computing and communication
significantly and expand dynamically with the cluster scale of Alibaba
Cloud.
ERDMA is a RDMA networking adapter based on the Alibaba MOC hardware. It
works in the VPC network environment (overlay network), and uses iWarp
transport protocol. ERDMA supports reliable connection (RC). ERDMA also
supports both kernel space and user space verbs. Now we have already
supported HPC/AI applications with libfabric, NoF and some other internal
verbs libraries, such as xrdma, epsl, etc,.
For the ECS instance with RDMA enabled, our MOC hardware generates two
kinds of PCI devices: one for ERDMA, and one for the original net device
(virtio-net). They are separated PCI devices.

we add some more features, such as non-blocking iw_connect implementation.

won't do any harm.
Let's fix that brittle design by skipping writing DPB entry altogether
