830382e4cc Merge branch 'bpf: remove bpf_load loader completely'
"Daniel T. says:

====================

Numerous refactoring that rewrites BPF programs written with bpf_load
to use the libbpf loader was finally completed, resulting in BPF
programs using bpf_load within the kernel being completely no longer
present.

This patchset refactors remaining bpf programs with libbpf and
completely removes bpf_load, an outdated bpf loader that is difficult
to keep up with the latest kernel BPF and causes confusion.

Changes in v2:
 - drop 'move tracing helpers to trace_helper' patch
 - add link pinning to prevent cleaning up on process exit
 - add static at global variable and remove unused variable
 - change to destroy link even after link__pin()
 - fix return error code on exit
 - merge commit with changing Makefile

Changes in v3:
 - cleanup bpf_link, bpf_object and cgroup fd both on success and error

0afe0a998c samples: bpf: Fix lwt_len_hist reusing previous BPF map
Currently, lwt_len_hist's map lwt_len_hist_map is uses pinning, and the
map isn't cleared on test end. This leds to reuse of that map for
each test, which prevents the results of the test from being accurate.

This commit fixes the problem by removing of pinned map from bpffs.
Also, this commit add the executable permission to shell script
files.

c6497df0dd samples: bpf: Refactor test_overhead program with libbpf
This commit refactors the existing program with libbpf bpf loader.
Since the kprobe, tracepoint and raw_tracepoint bpf program can be
attached with single bpf_program__attach() interface, so the
corresponding function of libbpf is used here.

Rather than specifying the number of cpus inside the code, this commit
uses the number of available cpus with _SC_NPROCESSORS_ONLN.

763af200d6 samples: bpf: Refactor ibumad program with libbpf
This commit refactors the existing ibumad program with libbpf bpf
loader. Attach/detach of Tracepoint bpf programs has been managed
with the generic bpf_program__attach() and bpf_link__destroy() from
the libbpf.

Also, instead of using the previous BPF MAP definition, this commit
refactors ibumad MAP definition with the new BTF-defined MAP format.

To verify that this bpf program works without an infiniband device,
try loading ib_umad kernel module and test the program as follows:

    # modprobe ib_umad
    # ./ibumad

Moreover, TRACE_HELPERS has been removed from the Makefile since it is
not used on this program.

4fe6641526 samples: bpf: Refactor task_fd_query program with libbpf
This commit refactors the existing kprobe program with libbpf bpf
loader. To attach bpf program, this uses generic bpf_program__attach()
approach rather than using bpf_load's load_bpf_file().

To attach bpf to perf_event, instead of using previous ioctl method,
this commit uses bpf_program__attach_perf_event since it manages the
enable of perf_event and attach of BPF programs to it, which is much
more intuitive way to achieve.

Also, explicit close(fd) has been removed since event will be closed
inside bpf_link__destroy() automatically.

Furthermore, to prevent conflict of same named uprobe events, O_TRUNC
flag has been used to clear 'uprobe_events' interface.

d89af13c92 samples: bpf: Refactor test_cgrp2_sock2 program with libbpf
This commit refactors the existing cgroup program with libbpf bpf
loader. The original test_cgrp2_sock2 has keeped the bpf program
attached to the cgroup hierarchy even after the exit of user program.
To implement the same functionality with libbpf, this commit uses the
BPF_LINK_PINNING to pin the link attachment even after it is closed.

Since this uses LINK instead of ATTACH, detach of bpf program from
cgroup with 'test_cgrp2_sock' is not used anymore.

The code to mount the bpf was added to the .sh file in case the bpff
was not mounted on /sys/fs/bpf. Additionally, to fix the problem that
shell script cannot find the binary object from the current path,
relative path './' has been added in front of binary.

c5815ac7e2 samples: bpf: Refactor hbm program with libbpf
This commit refactors the existing cgroup programs with libbpf
bpf loader. Since bpf_program__attach doesn't support cgroup program
attachment, this explicitly attaches cgroup bpf program with
bpf_program__attach_cgroup(bpf_prog, cg1).

Also, to change attach_type of bpf program, this uses libbpf's
bpf_program__set_expected_attach_type helper to switch EGRESS to
INGRESS. To keep bpf program attached to the cgroup hierarchy even
after the exit, this commit uses the BPF_LINK_PINNING to pin the link
attachment even after it is closed.

Besides, this program was broken due to the typo of BPF MAP definition.
But this commit solves the problem by fixing this from 'queue_stats' map
struct hvm_queue_stats -> hbm_queue_stats.

617b860c18 net/mlx5: Treat host PF vport as other (non eswitch manager) vport
When eswitch manager is running on ECPF, host PF should be treated
as non eswitch manager port, similar to other VF vports.
Fail to do so, results in firmware treating PF's vport as ECPF
vport for eswitch ACL tables.
Non zero check to figure out if a given vport is other vport or not
is not sufficient becase PF vport number = 0 on ECPF.
Hence, create esw acl tables with an attribute of other vport.

5bef709d76 net/mlx5: Enable host PF HCA after eswitch is initialized
Currently ECPF enables external host PF too early in the initialization
sequence for Ethernet links when ECPF is eswitch manager.

Due to this, when external host PF driver is loaded, host PF's HCA CAP has
inner_ip_version supported by NIC RX flow table.
This capability is later updated by firmware after ECPF driver enables
ENCAP/DECAP as eswitch manager.

This results into a timing race condition, where CREATE_TIR command
fails with a below syndrome on host PF.

mlx5_cmd_check:775:(pid 510): CREATE_TIR(0x900) op_mod(0x0) failed,
status bad parameter(0x3), syndrome (0x562b00)

Hence, enable the external host PF after necessary eswitch and per vport
initialization is completed.
Continue to enable host PF when eswitch manager capability is off for a
ECPF.

8f2685c9c4 Memory controller drivers for v5.11 - Tegra SoC
There is a bigger work from Dmitry Osipenko around Tegra SoC memory
 controller drivers, mostly towards adding interconnect support and
 integration with devfreq.  This work touches all Tegra memory controller
 drivers and also few other SoC-related parts.  It's not yet finished but
 the intermediate stage seems ready to merge.
 
 Beside that Tegra 210 memory controller got few fixes and received new
 swgroups (work of Nicolin Chen).

The mxs-auart driver is only used for DT platforms and there is no
need to use the platform_device_id structure.

Get rid the platform_device_id structure and retrieve the data via
of_device_get_match_data(), which simplifies the code.

Merge series "regmap/SoundWire/ASoC: Add SoundWire SDCA support" from Bard Liao <yung-chuan.liao@linux.intel.com>:
The MIPI SoundWire Device Class standard will define audio functionality
beyond the scope of the existing SoundWire 1.2 standard, which is limited
to the bus and interface.

The description is inspired by the USB Audio Class, with "functions",
"entities", "control selectors", "audio clusters". The main difference
with the USB Audio class is that the devices are typically on a motherboard
and descriptors stored in platform firmware instead of being retrieved
from the device.

The current set of devices managed in this patchset are conformant with the
SDCA 0.6 specification and require dedicated drivers since the descriptors
and platform firmware specification is not complete at this time. They do
however rely on the hierarchical addressing required by the SDCA standard.
Future devices conformant with SDCA 1.0 should rely on a class driver.

This series adds support for the hierarchical SDCA addressing and extends
regmap. It then provides 3 codecs for RT711-sdca headset codec, RT1316
amplifier and RT715-scda microphone codec.

Note that the release of this code before the formal adoption of the
SDCA 1.0 specification was formally endorsed by the MIPI Board to make
sure there is no delay for Linux-based support of this specification.

Merge series "ASoC: merge soc_compr_open() rollback and soc_compr_free()" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
Hi Mark

soc_compr_open() does rollback when failed (A),
but, it is almost same as soc_compr_free().

	static int soc_compr_open(xxx)
	{
		...
		if (ret < 0)
			goto xxx_err;
		...
		return 0;

 ^	machine_err:
 |		...
 |	out:
(A)		...
 |	pm_err:
 |		...
 v		return ret;
	}

This kind of duplicated code can be a hotbed of bugs,
thus, this patch-set share soc_compr_free() and rollback.

  ASoC: soc-compress: move soc_compr_free() next to soc_compr_open()
  ASoC: soc-dai: add mark for snd_soc_dai_compr_startup/shutdown()

Coverity reports "Potentially overflowing expression ..." warning, which
is correct thing to complain from the compiler point of view, but this is
not possible in the current code. Still, this is a small error as there
are some future situations that might need to use a 32 bit offset. Use ULL
so the calculation works up to 63.
