Commit 33f082614c34 ("arm64: signal: Allow expansion of the signal
frame") introduced the BASE_SIGFRAME_SIZE macro but it has
apparently never been used.

Nit: Should there be a statement of what the patch does?

Same throughout the series.

(Yes, I know it's in the subject line, but Mutt doesn't think that's
part of the message body, so I can't see it now that I'm replying...
and submitting-patches.rst and e.g., maintainer-tip.rst seem to take
the same policy, albeit without quite stating it explicitly.)

Weird.  Maybe there are places where this could have been used, but I
guess we have managed fine without it.

Or possibly some unmerged version of the SVE patches used this but it
disappeared in refactoring.

Either way:

Ah good point, I didn't consider that. Will make it explicit in patch 1
and 2.

Thanks.

(I have a patch for submitting-patches.rst knocking about to propose
making this more explicit, but I didn't dare to post it so far...)
