Just to be clear here: There was an ABI document that required PT_NOTE
parsing.  The Linux kernel does *not* define the x86-64 ABI, it only
implements it.  The authoritative source should be the ABI document.

In this particularly case, so far anyone implementing this ABI extension
tried to provide value by changing it, sometimes successfully.  Which
makes me wonder why we even bother to mainatain ABI documentation.  The
kernel is just very late to the party.

Thanks,
Florian
