From f021c8b334cc00739b5d43b5be5f97a34b1ad16a Mon Sep 17 00:00:00 2001 From: Isaku Yamahata Date: Fri, 17 Oct 2008 11:17:54 +0900 Subject: ia64/xen: xencomm conversion functions for hypercalls On ia64/xen, pointer arguments for hypercall is passed by pseudo physical address(guest physical address.) So such hypercalls needs address conversion functions. This patch implements concrete conversion functions for such hypercalls.
