That's lame, what about building for testing?
And is this needed now, for 5.0-final, or can it wait for 5.1? What
changed to require this?
tahnks,

Do you mean this instead?
depends on (ARCH_STRATIX10 && HAVE_ARM_SMCCC) || COMPILE_TEST

This change will reduce kernel size for most arm64. It can go into
whichever kernel. We can resubmit allowing for COMPILE_TEST.

Nothing, we just didn't catch this. We're used to having our own
defconfig. Not used to having a single defconfig that is shared.
Thanks for the review comments,

I don't see how this is true? ARM64 has a single defconfig and
ARCH_STRATIX10 is included in that defconfig. I don't see how adding
this dependency will reduce the kernel size for most arm64?

Yes, that would be better, right?

So it's not fixing a bug, but rather just allowing you to shrink an
image? If so, then 5.1 is good.
Please resubmit, after making sure it doesn't break the normal builds :)

Sorry, I wasn't clear. By default it will be built in since there's
one arm64 defconfig. But adding ARCH_STRATIX10 dependency here
supports users who turn off all the ARCH_* they don't care about in
their own defconfig that won't get upstreamed.
