I'd tried the srcrev change on master next and it worked. I've taked
your patch, thanks!

I don't want to break things too badly given it is the holidays but I
do want to keep patches moving. I've therefore taken most of your
series except the bits making the default 6.18.

This gets us on the new point releases, bumps the CVE info, drops 6.17
and adds 6.18 for testing along with switching to the 6.18 headers.

I included the cryptodev-module tweak, the ltp fix, the strace fixes
and a tweak to increase the initramfs size by 20MB.

The initramfs issue is genericarm64 specific and Mikko was in favour of
increasing the initramfs size. I am a bit worried about the size issues
there but that is a bigger issue to think about at a different time.

This does leave genericarm64 kernel config warnings:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/60/builds/2902
https://autobuilder.yoctoproject.org/valkyrie/#/builders/22/builds/2933

meta-arm failures:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/75/builds/2786

meta-virt failures:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/89/builds/2761

as the issues we need to resolve before we change the default to 6.18.
Hopefully a sensible compromise for the holidays! :)

Cheers,
