A small update: I have folded this fixup into this patch
and the hexagon one, to ensure we don't define both
__NR_sync_file_range2 and __NR_sync_file_range. I already
have patches to clean this up further to avoid both the
#undef and #define, but that is part of a larger rework
that is not ready before the merge window.
