This is because we try to copy the whole ip/ip6 address to the flow_key,
while we only point the to ip/ip6 saddr. Note that since these are UAPI
headers, __struct_group() is used to avoid the compiler warnings.

An external PHY needs settling time after power up or reset.
In the bind() function an mdio bus is registered. If at this point
the external PHY is still initialising, no valid PHY ID will be
read and on phy_find_first() the bind() function will fail.
If an external PHY is present, wait the maximum time specified
in 802.3 45.2.7.1.1.

Since 2df8220cc511 ("kbuild: build init/built-in.a just once"),
generating Debian packages using 'make bindeb-pkg' results in
packages that are stuck to the same .version, leading to unexpected
behaviours (multiple packages with the same version).
That's because the mkdebian script samples the build version
before building the kernel, and forces the use of that version
number for the actual build.
Restore the previous behaviour by calling init/build-version
instead of reading the .version file. This is likely to result
in too many .version bumps, but this is what was happening before
(although the bump was affecting builds made after the current one).

Add LARA-L6 PIDs for three different USB compositions.
LARA-L6 module can be configured (by AT interface) in three different
USB modes:
* Default mode (Vendor ID: 0x1546 Product ID: 0x1341) with 4 serial
interfaces
* RmNet mode (Vendor ID: 0x1546 Product ID: 0x1342) with 4 serial
interfaces and 1 RmNet virtual network interface
* CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1343) with 4 serial
interface and 1 CDC-ECM virtual network interface
In default mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions
In RmNet mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser

The perf build currently has a '-Itools/lib' on the CC command

impossible to override include behavior.
Change the libsymbol build mirroring the libbpf, libsubcmd, libapi,

A later change will modify the include behavior. Don't build kallsyms.o
as part of util as this will lead to duplicate definitions. Add
kallsym's directory to the MANIFEST rather than individual files, so
that the Build and Makefile are added to a source tar ball.

The perf build currently has a '-Itools/lib' on the CC command
line. This causes issues as the libapi, libsubcmd, libtraceevent,
libbpf headers are all found via this path, making it impossible to
override include behavior.
Change the libperf build mirroring the libbpf, libsubcmd and libapi
build, so that it is installed in a directory along with its headers. A
later change will modify the include behavior.

On embedded systems with little memory and no relevant
security concerns, it is beneficial to reduce the size
of the table.
Reducing the size from 2^16 to 2^8 saves 255 KiB
of kernel RAM.
Makes the table size configurable as an expert option.
The size was previously increased from 2^8 to 2^16
in commit 4c2c8f03a5ab ("tcp: increase source port perturb table to
2^16").

In mmc_select_voltage(), if there is no full power cycle, the voltage
range selected at the end of the function will be on a single range
(e.g. 3.3V/3.4V). To keep a range around the selected voltage (3.2V/3.4V),
the mask shift should be reduced by 1.
This issue was triggered by using a specific SD-card (Verbatim Premium
16GB UHS-1) on an STM32MP157C-DK2 board. This board cannot do UHS modes
and there is no power cycle. And the card was failing to switch to
high-speed mode. When adding the range 3.2V/3.3V for this card with the
proposed shift change, the card can switch to high-speed mode.

sk->sk_user_data has multiple users, which are not compatible with each
other. Writers must synchronize by grabbing the sk->sk_callback_lock.
l2tp currently fails to grab the lock when modifying the underlying tunnel
socket fields. Fix it by adding appropriate locking.
We err on the side of safety and grab the sk_callback_lock also inside the
sk_destruct callback overridden by l2tp, even though there should be no
refs allowing access to the sock at the time when sk_destruct gets called.
v4:
- serialize write to sk_user_data in l2tp sk_destruct
v3:
- switch from sock lock to sk_callback_lock
- document write-protection for sk_user_data
v2:
- update Fixes to point to origin of the bug
- use real names in Reported/Tested-by tags

Normally, --for-each-cgroup only works with AGGR_GLOBAL. However
the --topdown on some cpu (e.g. Intel Skylake) converts it to the
AGGR_CORE internally.
To support those machines, add print_aggr_cgroup and handle the events
like in print_cgroup_events().
$ perf stat -a --for-each-cgroup system.slice,user.slice --topdown sleep 1
nmi_watchdog enabled with topdown. May give wrong results.

When we have events for each cgroup, the metric should be printed for
each cgroup separately. Add print_cgroup_counter() to handle that
situation properly.
Also change print_metric_headers() not to print duplicate headers
by checking cgroups.

The prefix is needed for interval mode to print timestamp at the
beginning of each line. But the it's tricky for the metric only
mode since it doesn't print every evsel and combines the metrics
into a single line.
So it needed to pass 'first' argument to print_counter_aggrdata()
to determine if the current event is being printed at first. This
makes the code hard to read.
Let's move the logic out of the function and do it in the outer
print loop. This would enable further cleanups later.

There are print_header() and print_interval() to print header lines before
actual counter values. Also print_metric_headers() needs to be called for
the metric-only case.
Let's move all these logics to a single place including num_print_iv to
refresh the headers for interval mode.

timestamp in the buffer as a prefix. To reduce the confusion, factor
