it
original XML files

I can supply pristine (larger) XML files (see attached). However, I cannot
supply a binary for the "old" file as it wasn't preserved. The "new" binary=
 is
317MiB and we'd need some bespoke means to get it to you.

The "old" XML file was generated by an abidw built from our internal git br=
anch
(the major difference from upstream at the time being the symtab reader); it
was a (stale) user-generated kernel ABI for an AOSP kernel, pending commit.=
 The
"new" XML file was generated by an abidw having one extra commit (relating =
to
an ELF symbol issue); it was generated by CI infrastructure to capture the
kernel ABI as of the pending commit.

In short, reproducing the issue from binaries isn't feasible due the diffic=
ulty
/ impossibility of reproducing the build environment of the "old" kernel AB=
I.
However, the debugging I did earlier really points to this being an issue w=
ith
diff categorisation.
