From a3863f68b0d7fe2073c0f4efe534ec87a685c4fa Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Mon, 7 Jan 2008 11:05:31 -0200 Subject: lguest: make emulate_insn receive a vcpu struct. emulate_insn() needs to know about current eip, which will be, in the future, a per-vcpu thing. So in this patch, the function prototype is modified to receive a vcpu struct Signed-off-by: Glauber de Oliveira Costa Signed-off-by: Rusty Russell --- drivers/lguest/x86/core.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'drivers/lguest') diff --git a/drivers/lguest/x86/core.c b/drivers/lguest/x86/core.c index d35f6299c92f..ae46c6b1f2f9 100644 --- a/drivers/lguest/x86/core.c +++ b/drivers/lguest/x86/core.c @@ -218,8 +218,9 @@ void lguest_arch_run_guest(struct lg_cpu *cpu) * When the Guest uses one of these instructions, we get a trap (General * Protection Fault) and come here.
