I only noticed it today, given the thing selects with it's likely that
as you say it's been triggered by a change in another tree rather than
having been an issue in itself.

Indeed, the initial reason I set up my builder was that I was doing work
on arm64 and got fed up with the constant breakage in -next.  It's
getting better slowly, we mostly at least compile now which wasn't the
case originally.

Yes, it'll be the combination of the two commits (hopefully whatever
patch introduced the issue builds on its own branch as well).  There's a
fix been merged into -next somewhere which fixes this - like I said I'm
fairly sure that's 626ffb400e1e781 (firmware: qcom: scm: Add function
stubs for ARM64) which means that an alternative stub implementation in
qcom_scm-64.c gets build on arm64 but that's not hit mainline yet and
we're getting near the end of the merge window.

It would be sad to have yet another release where -rc1 doesn't build for
common test configurations :/
