From 5a19b78972c39be0c5378c14c23e6c998683e80f Mon Sep 17 00:00:00 2001 From: Andy King Date: Tue, 22 Jan 2013 09:15:04 -0800 Subject: VMCI: Fix broken context ID retrieval I'm an idiot. The context ID can be a really large unsigned number, which means it'll appear negative as an int. So actually the right fix here is just to set it regardless of the returned value (but only for this particular hypercall; normally we would check it).
