You're probably wondering why there are changes to SPARC in that patchset? :)

Libsanitizer doesn't even build have the time on sparc, the release
manager has to hand patch it into building again every major release
because of the way ASAN development is done out of tree and local
commits to the gcc tree are basically written over during the
next merge.

Libsanitizer is userspace lib it's for userspace ASan, KASan doesn't use it.
We have our own 'libsanitzer' in kernel.

I was speaking about ASAN development in general, of which the
libsanitizer issue is a byproduct.
