Subject: [PATCH] KVM: ia64: remove

KVM for ia64 has been marked as broken not just once, but twice even,
and the last patch from the maintainer is now roughly 5 years old.
Time for it to rest in piece.

Signed-off-by: Paolo Bonzini <pbonzini@...hat.com>
---
	The patch was edited to keep its size decent, by dropping
	all the removed lines from the deleted files.
