Hi Naresh and Sasha,
so this fix (unluckily) applies cleanly to v5.15 but fails to build since the logic and code around it was different in v5.15.
While looking at backporting it properly, though, I realized that the fix is NOT needed really in v5.15 due to the different context and logic, so I ask you to DROP this fix in v5.15.
I suppose the patch has been automatically applied because the Fixes referred a commit that was on v5.15 too since some of those lines were indeed impacted and were present also in later versions, but the logic around it has changed afterwards, so the original code (up to v5.17) was not really affected by the bug addressed by this fix...only later versions from v5.18 (included) onwards needs it.
Moreover note that the whole SMC ISR logic was introduced in v5.12 (and was good up to v5.17 as said) so v5.15 is really the only stable release that needs to drop this fix.
Thanks and sorry for the noise, Cristian

What's the SHA of the patch that you are referring to (in linux-5.15.y) that you're suggesting the stable maintainers revert?

Yes, this is a patch that was recently added to the stable queue for 5.15 and it is still pending AFAIU (I suppose since it failed to build once applied).
There is another previous failed build report from yesterday:
