bpf_link_get_from_fd currently returns a NULL fd for LSM programs.
LSM programs are similar to tracing programs and can also use
skel_raw_tracepoint_open.

There were some recent questions about where and why to use the
random_kstack routines when applying them to new architectures[1].
Update the header comments to reflect the design choices for the
routines.

Like in 'perf report' and 'perf top', Add this option to limit the
number of functions it displays based on the overhead value in percent.
This affects only stdio and stdio2 output modes. Without this, it
shows very long disassembly lines for every function in the data
file. If users don't want this behavior, they can set a value in
percent to suppress that.

This patch adds up test cases that handles 4 combinations:
a) outer map: BPF_MAP_TYPE_ARRAY_OF_MAPS
inner maps: BPF_MAP_TYPE_ARRAY and BPF_MAP_TYPE_HASH
b) outer map: BPF_MAP_TYPE_HASH_OF_MAPS
inner maps: BPF_MAP_TYPE_ARRAY and BPF_MAP_TYPE_HASH

This patch extends batch operations support for map-in-map map-types:
BPF_MAP_TYPE_HASH_OF_MAPS and BPF_MAP_TYPE_ARRAY_OF_MAPS
A usecase where outer HASH map holds hundred of VIP entries and its
associated reuse-ports per VIP stored in REUSEPORT_SOCKARRAY type
inner map, needs to do batch operation for performance gain.
This patch leverages the exiting generic functions for most of the batch
operations. As map-in-map's value contains the actual reference of the inner map,
for BPF_MAP_TYPE_HASH_OF_MAPS type, it needed an extra step to fetch the
map_id from the reference value.
selftests are added in next patch 2/2.

The idx is with respect to evlist not evsel. That hasn't mattered because
they are the same at present. Prepare for that not being the case, which it

A user told me that bpf_jit_enable can be disabled on one system, but he
failed to disable bpf_jit_enable on the other system:
# echo 0 > /proc/sys/net/core/bpf_jit_enable
bash: echo: write error: Invalid argument
No useful info is available through the dmesg log, a quick analysis shows
that the issue is related with CONFIG_BPF_JIT_ALWAYS_ON.
When CONFIG_BPF_JIT_ALWAYS_ON is enabled, bpf_jit_enable is permanently set
to 1 and setting any other value than that will return failure.
It is better to print some info to tell the user if disable bpf_jit_enable
failed.

Ath11k allocates memory when firmware requests memory in QMI.
Coldboot calibration and firmware recovery uses firmware reload.
On firmware reload, firmware sends memory request again. If Ath11k
allocates memory on first firmware boot, reuse the available
memory. Also check if the segment type and size is same
on the next firmware boot. Reuse if segment type/size is
same as previous firmware boot else free the segment and
allocate the segment with size/type.

In case of Passpoint, the WLAN interface may be requested to
remain on a specific channel and then to send some management
frames on that channel. Now chanfreq of wmi_mgmt_send_cmd is set
as 0, as a result firmware may choose a default but wrong channel.
Fix it by assigning chanfreq field with the designated channel.
This change only applies to WCN6855 and QCA6390, other chips are
not affected.

Commit 66307ca04057 ("ath11k: fix mgmt_tx_wmi cmd sent to FW for
deleted vdev") wants both of below two conditions are true before
sending management frames:
1: ar->allocated_vdev_map & (1LL << arvif->vdev_id)
2: arvif->is_started
Actually the second one is not necessary because with the first one
we can make sure the vdev is present.
Also use ar->conf_mutex to synchronize vdev delete and mgmt. TX.
This issue is found in case of Passpoint scenario where ath11k
needs to send action frames before vdev is started.
Fix it by removing the second condition.

With WoWLAN enabled and after sleeping for a rather long time,
we are seeing that with some APs, it is not able to wake up
the STA though the correct wake up pattern has been configured.
This is because the host doesn't send keepalive command to
firmware, thus firmware will not send any packet to the AP and
after a specific time the AP kicks out the STA.
Fix this issue by enabling keepalive before going to suspend
and disabling it after resume back.

del_timer() does not wait until the timer handler finishing.
This means that the timer handler may still be running after
the driver's remove function has finished, which would result
in a use-after-free.

The host stream position is updated when no_stream_position is set as 0.
However current implementation updates host stream position only when
report data is larger than or equal to host period size which is decided
by the period size of host side. It maybe cause host stream position
update not in time. Therefore this patch introduces another field
"cont_update_posn", a boolean value aimed to update host stream position
continuously and based on period size of pipeline. It can get better
precise when need to update host stream position from firmware.

The SOF topology supports 2 BE Links(dmic01 and dmic16k) and each
link supports up to four DMICs. However, Chromebook does not implement
ACPI NHLT table so the mach->mach_params.dmic_num is always zero. We
add a quirk so machine driver knows it's running on a Chromebook and
need to create BE Links for DMIC.

Expose mlx5_sriov_blocking_notifier_register / unregister APIs to let a
VF register to be notified for its enablement / disablement by the PF.
Upon VF probe it will call mlx5_sriov_blocking_notifier_register() with
its notifier block and upon VF remove it will call
mlx5_sriov_blocking_notifier_unregister() to drop its registration.
This can give a VF the ability to clean some resources upon disable
before that the command interface goes down and on the other hand sets
some stuff before that it's enabled.
This may be used by a VF which is migration capable in few cases.(e.g.
PF load/unload upon an health recovery).
