That's not what I was referring to, but it is fine to fix that too.

What I meant was that the first column of the patch body is corrupted.
Your v2 has hunks like this (bad):

static Elf32_Word read_elf_word(Elf32_Word word, bool swap)
{
-	return swap ? bswap_32(word) : word;
+	return swap ? swab32(word) : word;
}


Your v3 has this (good):

 static void write_elf_word(Elf32_Word val, Elf32_Word *dst, bool swap)
 {
-	*dst = swap ? bswap_32(val) : val;
+	*dst = swap ? swab32(val) : val;
 }
