IIRC introduced for ia64.  But isn't the correct action adding it to
qemu.git instead of removing it completely?
Adding something to qemu.git, yes, keeping it here without knowing the
final code, no.
This is called introducing a regression.
There is nothing to regress here.

This is just another unused variation from upstream.
It's wasn't unused when ia64 was alive.  Just removing it means more
work later to rediscover it (and anyway ppc needs it).
ppc is not used with qemu-kvm, it's used with qemu upstream. qemu-kvm is
a x86-only show today.

Does qemu.git have this hook for ppc?
