My preferred way of getting arm/arm64 defconfig updates is to have
them picked up by the platform maintainer, the same way we handle
updates to dts files. The platform maintainers are familiar with the
process and will send the patches on to me for integration through
the soc tree.

If a change is not specific to any particular platform, I recommend
to send it to:soc at kernel.org, cc:lakml. This makes it show up in
my patchwork, so I will eventually get around to picking it up.

When you do this, it's helpful to me if you include an explanation
(after the --- line) why this patch does not get picked up by
a platform maintainer, and it also helps me to include whether
I should include it in the current (6.10) fixes or queue it for
the next merge window.
