72d99b395f drm/amdgpu: turn back rlcg write for gfx_v10
There is no need to use amdgpu_mm_wreg_mmio_rlc()
during initialization time because this interface
is only designed for debugfs case to access the
registers which are only permitted by RLCG during
run-time. Therefore, turn back rlcg write for gfx_v10.
If we not turn back it, it will raise amdgpu load failure.

933496e9cc SUNRPC: 'Directory with parent 'rpc_clnt' already present!'
Each rpc_client has a cl_clid which is allocated from a global ida, and
a debugfs directory which is named after cl_clid.

We're releasing the cl_clid before we free the debugfs directory named
after it.  As soon as the cl_clid is released, that value is available
for another newly created client.

That leaves a window where another client may attempt to create a new
debugfs directory with the same name as the not-yet-deleted debugfs
directory from the dying client.  Symptoms are log messages like

	Directory 4 with parent 'rpc_clnt' already present!

====================
net: qed/qede: critical hw error handling

FastLinQ devices as a complex systems may observe various hardware
level error conditions, both severe and recoverable.

Driver is able to detect and report this, but so far it only did
trace/dmesg based reporting.

Here we implement an extended hw error detection, service task
handler captures a dump for the later analysis.

I also resubmit a patch from Denis Bolotin on tx timeout handler,
addressing David's comment regarding recovery procedure as an extra
reaction on this event.

v2:

Removing the patch with ethtool dump and udev magic. Its quite isolated,
I'm working on devlink based logic for this separately.

e92888c72f bpf: Enforce returning 0 for fentry/fexit progs
Currently, tracing/fentry and tracing/fexit prog
return values are not enforced. In trampoline codes,
the fentry/fexit prog return values are ignored.
Let us enforce it to be 0 to avoid confusion and
allows potential future extension.

This patch also explicitly added return value
checking for tracing/raw_tp, tracing/fmod_ret,
and freplace programs such that these program
return values can be anything. The purpose are
two folds:
 1. to make it explicit about return value expectations
    for these programs in verifier.
 2. for tracing prog_type, if a future attach type
    is added, the default is -ENOTSUPP which will
    enforce to specify return value ranges explicitly.

0531b0357b selftests: fix flower parent qdisc
Flower tests used to create ingress filter with specified parent qdisc
"parent ffff:" but dump them on "ingress". With recent commit that fixed
tcm_parent handling in dump those are not considered same parent anymore,
which causes iproute2 tc to emit additional "parent ffff:" in first line of
filter dump output. The change in output causes filter match in tests to
fail.

Prevent parent qdisc output when dumping filters in flower tests by always
correctly specifying "ingress" parent both when creating and dumping
filters.

625236ba38 security: Fix the default value of secid_to_secctx hook
security_secid_to_secctx is called by the bpf_lsm hook and a successful

LSM framework. The current behaviour return success when the pointer
isn't initialized when CONFIG_BPF_LSM is enabled, with the default
return from kernel/bpf/bpf_lsm.c.

Rework the so the default return value is -EOPNOTSUPP.

There are likely other callbacks such as security_inode_getsecctx() that
may have the same problem, and that someone that understand the code
better needs to audit them.

Thank you Arnd for helping me figure out what went wrong.

fba5618451 dt-bindings: Fix incorrect 'reg' property sizes
The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.
