That doesn't actually look all that bad for -rc1. Several of them already have fixes, and most of the rest look "easily fixable". Famous last words. The most worrisome ones are probably the stack frame complaint ones (libzstd and a couple of powerpc ones) that Geert also reported, but they might at least to some degree be as simple as just due to the same excessive inlining that was already fingered for the code bloat. But it could be more fundamental - the kernel just doesn't like stack allocations the same way user space does, so the sync-up to a newer libzstd might be a bit more problematic than just "don't force inlining". Nick - you've been cc'd twice because you sign off your commits with your work email, but then seem to actually prefer the personal one, so I didn't know which to use and just added both.
