In function st95hf_in_send_cmd, the variable rc is assigned then goto
error label, which just returns rc, so we use return to replace it.
Since error label only used once in the function, so we remove error label.

Fix the sparse warnings in the ixgbe crypto offload code. These
changes were made in the most conservative way (force cast)
in order to hopefully not break the code. I suspect that the
code might still be broken on big-endian architectures, but
no one is complaining, so I'm just leaving it functionally
the same.

The ixgbe hardware needs some very specific programming for
certain registers, which led to some misguided usage of ntohs
instead of using be16_to_cpu(), as well as a home grown swap
followed by an ntohs. Sparse didn't like this at all, and this
fixes the C=2 build, with code that uses native kernel interface.

The igb PTP code was using htons() on a constant to try to
byte swap the value before writing it to a register. This byte
swap has the consequence of triggering sparse conflicts between
the register write which expect cpu ordered input, and the code
which generated a big endian constant. Just override the cast
to make sure code doesn't change but silence the warning.
Can't do a __swab16 in this case because big endian systems
would then write the wrong value.

The igb driver was trying hard to be sparse correct, but somehow
ended up converting a variable into little endian order and then
tries to OR something with it.
A much plainer way of doing things is to leave all variables and
OR operations in CPU (non-endian) mode, and then convert to
little endian only once, which is what this change does.
This probably fixes a bug that might have been seen only on
big endian systems.

The sparse build (C=2) finds some issues with how the driver
dealt with the (very difficult) hardware that in some generations
uses little-endian, and in others uses big endian, for the VLAN
field. The code as written picks __le16 as a type and for some
hardware revisions we override it to __be16 as done in this
patch. This impacted the VF driver as well so fix it there too.
Also change the vlan_tci assignment to override the sparse
warning without changing functionality.

The sparse checker (C=2) found an assignment where we were mixing
types when trying to convert from data read directly from the
device NVM, to an array in CPU order in-memory, which
unfortunately the driver tries to do in-place.
This is easily solved by using the swap operation instead of an
assignment, and is already proven in other Intel drivers to be
functionally correct and the same code, just without a sparse
warning.
The change is the same in all three drivers.

Patches 2 and 3 remove warning/error log output that could be flooded.
Patch 4 performs more validation on address advertisement echo packets

when Linux receives an echo-ed ADD_ADDR, it checks the IP address against
the list of "announced" addresses. In case of a positive match, the timer
that handles retransmissions is stopped regardless of the 'Address Id' in
the received packet: this behaviour does not comply with RFC8684 3.4.1.
Fix it by validating the 'Address Id' in received echo-ed ADD_ADDRs.
Tested using packetdrill, with the following captured output:

if the register is a known constant. Given in this case we do not apply
any masking, there is also no reason for the operation to be truncated
under the speculative domain.
Therefore, there is also zero reason for the verifier to branch-off and
simulate this case, it only needs to do it for unknown but bounded scalars.
As a side-effect, this also enables few test cases that were previously

Merge tag 'perf-tools-fixes-for-v5.13-2021-05-24' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tool fixes from Arnaldo Carvalho de Melo:
- Fix 'perf script' decoding of Intel PT traces for abort handling and
sample instruction bytes.
- Add missing PERF_IP_FLAG_CHARS for VM-Entry and VM-Exit to Intel PT
'perf script' decoder.
- Fixes for the python based Intel PT trace viewer GUI.
- Sync UAPI copies (unwire quotactl_path, some comment fixes).
- Fix handling of missing kernel software events, such as the recently
added 'cgroup-switches', and add the trivial glue for it in the
tooling side, since it was added in this merge window.
- Add missing initialization of zstd_data in 'perf buildid-list',
detected with valgrind's memcheck.
- Remove needless event enable/disable when all events uses BPF.
- Fix libpfm4 support (63) test error for nested event groups.
