yamllint has a quoted string check. Enable the check aligned with the
DT schema style which is only using quotes when necessary with the
exception of regex patterns. There's also the frequent occurrence of '/'
which we allow rather than fixing.

For LDX_B/H/W, when zext has been inserted by verifier, it'll return 1,
and no exception handling will continue. Also, when the offset is 12-bit
value, the redundant zext inserted by the verifier is not removed. Fix
both scenarios by moving down the removal of redundant zext.

Toke Høiland-Jørgensen says:
====================
samples/bpf: Remove unmaintained XDP sample utilities
The samples/bpf directory in the kernel tree started out as a way of showcasing
different aspects of BPF functionality by writing small utility programs for
each feature. However, as the BPF subsystem has matured, the preferred way of
including userspace code with a feature has become the BPF selftests, which also
have the benefit of being consistently run as part of the BPF CI system.
As a result of this shift, the utilities in samples/bpf have seen little love,
and have slowly bitrotted. There have been sporadic cleanup patches over the
years, but it's clear that the utilities are far from maintained.
For XDP in particular, some of the utilities have been used as benchmarking aids
when implementing new kernel features, which seems to be the main reason they
have stuck around; any updates the utilities have seen have been targeted at
this use case. However, as the BPF subsystem as a whole has moved on, it has
become increasingly difficult to incorporate new features into these utilities
because they predate most of the modern BPF features (such as kfuncs and BTF).
Rather than try to update these utilities and keep maintaining them in the
kernel tree, we have ported the useful features of the utilities to the
xdp-tools package. In the porting process we also updated the utilities to take
advantage of modern BPF features, integrated them with libxdp, and polished the
user interface.
As these utilities are standalone tools, maintaining them out of tree is
simpler, and we plan to keep maintaining them in the xdp-tools repo. To direct
users of these utilities to the right place, this series removes the utilities
from samples/bpf, leaving in place only a couple of utilities whose
functionality have not yet been ported to xdp-tools.
The xdp-tools repository is located on Github at the following URL:
https://github.com/xdp-project/xdp-tools
The commits in the series removes one utility each, explaining how the
equivalent functionality can be obtained with xdp-tools.
v2:
- Add equivalent xdp-tools commands for each removed utility
v3:
- Add link to xdp-tools in the README

samples/bpf: Remove the xdp_redirect* utilities

The functionality of this utility is covered by the xdpdump utility in
xdp-tools.
There's a slight difference in usage as the xdpdump utility's main focus is
to dump packets before or after they are processed by an existing XDP
program. However, xdpdump also has the --load-xdp-program switch, which
will make it attach its own program if no existing program is loaded. With
this, xdp_sample_pkts usage can be converted as:
xdp_sample_pkts eth0
--> xdpdump --load-xdp-program eth0
To get roughly equivalent behaviour.

The functionality of these utilities have been incorporated into the
xdp-bench utility in xdp-tools.
Equivalent functionality is:
xdp1 eth0
--> xdp-bench drop -p parse-ip -l load-bytes eth0
xdp2 eth0
--> xdp-bench drop -p swap-macs eth0
Note that there's a slight difference in behaviour of those examples: the
swap-macs operation of xdp-bench doesn't use the bpf_xdp_load_bytes()
helper to load the packet data, whereas the xdp2 utility did so
unconditionally. For the parse-ip action the use of bpf_xdp_load_bytes()
can be selected by the '-l load-bytes' switch, with the difference that the
xdp-bench utility will perform two separate calls to the helper, one to
load the ethernet header and another to load the IP header; where the xdp1
utility only performed one call always loading 60 bytes of data.

The functionality of this utility has been incorporated into the xdp-bench
utility in xdp-tools, by way of the --rxq-stats argument to the 'drop',
'pass' and 'tx' commands of xdp-bench.
Some examples of how to convert xdp_rxq_info invocations into equivalent
xdp-bench commands:
xdp_rxq_info -d eth0
--> xdp-bench pass --rxq-stats eth0
xdp_rxq_info -d eth0 -a XDP_DROP -m
--> xdp-bench drop --rxq-stats -p swap-macs eth0

These utilities have all been ported to xdp-tools as functions of the
xdp-bench utility. The four different utilities in samples are incorporated
as separate subcommands to xdp-bench, with most of the command line
parameters left intact, except that mandatory arguments are always
positional in xdp-bench. For full usage details see the --help output of
each command, or the xdp-bench man page.
Some examples of how to convert usage to xdp-bench are:
xdp_redirect eth0 eth1
--> xdp-bench redirect eth0 eth1
xdp_redirect_map eth0 eth1
--> xdp-bench redirect-map eth0 eth1
xdp_redirect_map_multi eth0 eth1 eth2 eth3
--> xdp-bench redirect-multi eth0 eth1 eth2 eth3
xdp_redirect_cpu -d eth0 -c 0 -c 1
--> xdp-bench redirect-cpu -c 0 -c 1 eth0
xdp_redirect_cpu -d eth0 -c 0 -c 1 -r eth1
--> xdp-bench redirect-cpu -c 0 -c 1 eth0 -r redirect -D eth1

This utility has been ported as-is to xdp-tools as 'xdp-monitor'. The only
difference in usage between the samples and xdp-tools versions is that the
'-v' command line parameter has been changed to '-e' in the xdp-tools
version for consistency with the other utilities.

The current PCIe driver assumes PERST# is asserted when probe() is invoked.
Some older versions of the 2711/RPi bootloader left PERST# unasserted, as
the Raspian OS does assert PERST# on probe(). For this reason, we assert
PERST# for BCM2711 SOCs (i.e. RPi).

Currently, in function bpf_obj_free_fields(), for local kptr,
a warning will be issued if the struct does not contain any
special fields. But actually the kernel seems totally okay
with a local kptr without any special fields. Permitting
no special fields also aligns with future percpu kptr which
also allows no special fields.

Use hid_device for devm allocation of the input_dev name to avoid a

Reference the HID device rather than the input device for the devm

lppaca_shared_proc() takes a pointer to the lppaca which is typically
accessed through get_lppaca(). With DEBUG_PREEMPT enabled, this leads
to checking if preemption is enabled, for example:
BUG: using smp_processor_id() in preemptible [00000000] code: grep/10693
caller is lparcfg_data+0x408/0x19a0
CPU: 4 PID: 10693 Comm: grep Not tainted 6.5.0-rc3 #2
Call Trace:

check_preemption_disabled+0x214/0x220
lparcfg_data+0x408/0x19a0
...
This isn't actually a problem however, as it does not matter which
lppaca is accessed, the shared proc state will be the same.
vcpudispatch_stats_procfs_init() already works around this by disabling
preemption, but the lparcfg code does not, erroring any time
/proc/powerpc/lparcfg is accessed with DEBUG_PREEMPT enabled.
Instead of disabling preemption on the caller side, rework
lppaca_shared_proc() to not take a pointer and instead directly access
the lppaca, bypassing any potential preemption checks.

The only callers of zalloc_maybe_bootmem() are PCI setup routines. These
used to be called early during boot before slab setup, and also during
runtime due to hotplug.
But commit 5537fcb319d0 ("powerpc/pci: Add ppc_md.discover_phbs()")
moved the boot-time calls later, after slab setup, meaning there's no
longer any need for zalloc_maybe_bootmem(), kzalloc() can be used in all
cases.

Georgi writes:
interconnect changes for 6.6
This pull request contains the interconnect changes for the 6.6-rc1 merge
window which is a mix of core and driver changes with the following highlights:
Core changes:
- New generic test client driver that allows issuing bandwidth requests
between endpoints via debugfs.
- Annotate all structs with flexible array members with the __counted_by
attribute.
- Introduce new icc_bw_lock for cases where we need to serialize bandwidth
aggregation and update to decouple that from paths that require memory
allocation.
Driver changes:
- Move the Qualcomm SMD RPM bus-clocks from CCF to interconnect framework
where they actually belong. This brings power management improvements
and reduces the overhead and layering. These changes are in immutable
branch that is being pulled also into the qcom tree.
- Fixes for QUP nodes on SM8250.
- Enable sync_state and keepalive for QCM2290.
- Enable sync_state for SM8450.
- Improve enable_mask-based BCMs handling and fix some bugs.
- Add compatible string for the OSM-L3 on SDM670.
- Add compatible strings for SC7180, SM8250 and SM6350 bandwidth monitors.
- Expand and retire the DEFINE_QNODE and DEFINE_QBCM macros, which have
become ugly beasts with many different arguments.
