openbmc/linux dev-6.18

[Andrew Jeffery]

Hi all,

Linux v6.18 is a new long-term stable release[1], and I've now pushed a
branch[2] and corresponding recipe patches[3] moving OpenBMC over to
it.

[1]: https://www.kernel.org/category/releases.html
[2]: https://github.com/openbmc/linux/tree/dev-6.18
[3]: https://gerrit.openbmc.org/q/topic:%22openbmc-linux-dev-6.18%22

The patch migration was done in two steps, first from v6.12 to v6.17,
and then from v6.17 to v6.18. The multi-step effort was mainly a means
to test my own process. If anyone's interested in what that looks like
I'm happy to talk through it with you.

The patches listed below were either dropped or modified, listed by
step.

Please test dev-6.18 on your platforms and report any issues.

Andrew

Hi Andrew,

Thank you very much for pushing dev-6.18 to the OpenBMC Linux kernel
repository!

Do you have an estimate for when the dev-6.18 branch might become the
default branch for the OpenBMC Linux kernel?

Thanks,

Tomer

No problems :)

The serious answer is "when we've got consensus from the regular people
that it's a good idea".

Though if those people are quick perhaps we could hit merge as a
holiday celebration.

As an early indication, all changes in the Gerrit topic for the fixes
and recipe bumps have passed CI.
