From 15045275c32bf6d15d32c2eca8157be9c0ba6e45 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 22 Oct 2007 11:24:10 +1000 Subject: Remove old lguest I/O infrrasructure. This patch gets rid of the old lguest host I/O infrastructure and replaces it with a single hypercall "LHCALL_NOTIFY" which takes an address. The main change is the removal of io.c: that mainly did inter-guest I/O, which virtio doesn't yet support.
