2a84708c2f dt-bindings: gpio: rcar: Add r8a779a0 support
Document the compatible value for the GPIO block in the Renesas R-Car
V3U (R8A779A0) SoC.

While this GPIO block is mostly compatible with GPIO blocks on R-Car
Gen3 SoCs, there are small differences, and one of the new registers
needs to be configured differently from its initial reset state.

5ead723a20 lib/vsprintf: no_hash_pointers prints all addresses as unhashed
If the no_hash_pointers command line parameter is set, then
printk("%p") will print pointers as unhashed, which is useful for
debugging purposes.  This change applies to any function that uses
vsprintf, such as print_hex_dump() and seq_buf_printf().

A large warning message is displayed if this option is enabled.
Unhashed pointers expose kernel addresses, which can be a security
risk.

Also update test_printf to skip the hashed pointer tests if the
command-line option is set.

  but is mostly MM.  Was pulled in with akpm's agreement.

- Per-callback-batch tracking of numbers of callbacks,
  which enables better debugging information and smarter
  reactions to large numbers of callbacks.

- The first round of changes to allow CPUs to be runtime switched from and to
  callback-offloaded state.

- CONFIG_PREEMPT_RT-related changes.

- Addition of polling grace-period APIs for SRCU.

Several properties are shared between all TLMM bindings. By providing a
common binding to define these properties each platform's binding can be
reduced to just listing which of these properties should be checked for
- or further specified.

6a5df969ff docs: bpf: Clarify BPF_CMPXCHG wording
Based on [1], BPF_CMPXCHG should always load the old value into R0. The
phrasing in bpf.rst is somewhat ambiguous in this regard, improve it to
make this aspect crystal clear.

e276cfb9cd docs: networking: ti: Add driver doc for AM65 NUSS switch driver
J721e, J7200 and AM64 have multi port switches which can work in multi
mac mode and in switch mode. Add documentation explaining how to use
different modes.

58356eb31d net: ti: am65-cpsw-nuss: Add devlink support
AM65 NUSS ethernet switch on K3 devices can be configured to work either
in independent mac mode where each port acts as independent network
interface (multi mac) or switch mode.

Add devlink hooks to provide a way to switch b/w these modes.

Rationale to use devlink instead of defaulting to bridge mode is that
SoC use cases require to support multiple independent MAC ports with no
switching so that users can use software bridges with multi-mac
configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching
between multi mac and switch mode requires significant Port and ALE
reconfiguration, therefore is easier to be made as part of mode change
devlink hooks. It also allows to keep user interface similar to what
was implemented for the previous generation of TI CPSW IP
(on AM33/AM43/AM57 SoCs).
