Uh, you asked this on IRC and I answered ...

<tausq> if you changed the syscall abi, wouldn't you break all the
existing binaries?
<kyle> not if we kept the old one...
<tausq> ?
<tausq> then how do you implement what willy is talking about?
<willy> tausq: I'm not talking about changing the syscall ABI
<willy> I'm talking about getting rid of our wrappers for, eg,
parisc_truncate64()

We *already* use the "wrong" ABI in glibc.  That's why we have the
parisc_* syscalls.
