I'm confused, which commit should we add, or should we just revert what
we have now?

Sorry for the confusion. Let me try again:

1. efi: memmap: Move manipulation routines into x86 arch tree

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?h=linux-5.10.y&id=31e0721aeabde29371f624f56ce2f403508527a5

...breaks the build for ia64, because it requires a header that does not
exist before 8ff059b8531f3b98e14f0461859fc7cdd95823e4 for ia64.

2. efi: ia64: move IA64-only declarations to new asm/efi.h header

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8ff059b8531f3b98e14f0461859fc7cdd95823e4

adds this header and fixes the ia64 build, see for example [1].

From my understanding 31e0721aeabde29371f624f56ce2f403508527a5 should
not be merged w/o 8ff059b8531f3b98e14f0461859fc7cdd95823e4, which also
seems to be the case for all other stable kernels from linux-5.12.y up.

So 8ff059b8531f3b98e14f0461859fc7cdd95823e4 should be added, too, if
31e0721aeabde29371f624f56ce2f403508527a5 stays in.

And I thought that ia64 was dead?

No, actually it's alive and well - just currently outside of mainline -
but still in the stable kernels up to linux-6.6.y and for newer kernels
patched back in. If you want to check on our CI ([2]), all current
stable kernels build fine for ia64 and run in Ski - but linux-5.10.y
currently only because I manually added
8ff059b8531f3b98e14f0461859fc7cdd95823e4 to the list of patches applied
by the CI.
