When patching linux-libre-X.Y-source, is it possible to apply patches
per-architecture? I ask, because I'd like to apply an aarch64/arm64
patch, but would hate to trigger linux-libre rebuilds for all
architectures just to add trivial patches that would have no affect in
most architectures...


I've done basically this same patch for linux-libre@5.11 and @5.10, and
it would be nice to apply for @5.12, too. If we can't get architecture
specific conditionals, then it would be ideal to apply it at the same
time as the next version bump so as not to rebuild twice on all
architectures.
