The LVDS panel on this device uses 72.4 MHz pixel clock, set IMX8MP_VIDEO_PLL1
to 72.4 * 7 = 506.8 MHz so the LDB serializer and LCDIFv3 scanout engine can
reach accurate pixel clock of exactly 72.4 MHz.
Without this patch, the Video PLL1 frequency is the default set in imx8mp.dtsi
which is 1039.5 MHz, which divides down to inaccurate pixel clock of 74.25 MHz
which works for this particular panel by sheer chance.
Stop taking that chance and set correct accurate pixel clock frequency instead.

Linear Address Masking (LAM) has a weakness related to transient

Space Separation (LASS) is enabled this weakness may be exploitable.
Until kernel adds support for LASS[2], only allow LAM for COMPILE_TEST,
or when speculation mitigations have been disabled at compile time,
otherwise keep LAM disabled.
There are no processors in market that support LAM yet, so currently
nobody is affected by this issue.

Alexis Lothoré (eBPF Foundation) says:
====================
this series aims to bring test_tcp_check_syncookie.sh scope into
test_progs to make sure that the corresponding tests are also run
automatically in CI. This script tests for bpf_tcp_{gen,check}_syncookie
and bpf_skc_lookup_tcp, in different contexts (ipv4, v6 or dual, and
with tc and xdp programs).
Some other tests like btf_skc_cls_ingress have some overlapping tests with
test_tcp_check_syncookie.sh, so this series moves the missing bits from
test_tcp_check_syncookie.sh into btf_skc_cls_ingress, which is already
integrated into test_progs.
- the first three commits bring some minor improvements to
btf_skc_cls_ingress without changing its testing scope
- fourth and fifth commits bring test_tcp_check_syncookie.sh features
into btf_skc_cls_ingress
- last commit removes test_tcp_check_syncookie.sh
The only topic for which I am not sure for this integration is the
necessity or not to run the tests with different program types:
test_tcp_check_syncookie.sh runs tests with both tc and xdp programs, but
btf_skc_cls_ingress currently tests those helpers only with a tc
program. Would it make sense to also make sure that btf_skc_cls_ingress
is tested with all the programs types supported by those helpers ?
The series has been tested both in CI and in a local x86_64 qemu
environment:

Increase those helpers coverage by adding testing support for IPv4

brought earlier in test_tcp_check_syncookie.sh to cover some fixes
performed on those helpers, but test_tcp_check_syncookie.sh is not

There are a few global variables in btf_skc_cls_ingress.c, which are not
really used by different tests. Get rid of those global variables, by
performing the following updates:
- make srv_sa6 local to the main runner function
- make skel local to the main function, and propagate it through
function arguments
- get rid of duration by replacing CHECK macros with the ASSERT_XXX
macros. While updating those assert macros:
- do not return early on asserts performing some actual tests, let the
other tests run as well (keep the early return for parts handling
test setup)
- instead of converting the CHECK on skel->bss->linum, just remove it,
since there is already a call to print_err_line after the test to
