From 03c63b945239dc4abcf3a687beda6eb3b0cd69bc Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 3 Feb 2010 21:16:41 +0100 Subject: [PATCH] KVM: Make vmport KVM-compatible The vmport "device" accesses the VCPU registers, so it requires proper cpu_synchronize_state. Add it to vmport_ioport_read, which also synchronizes vmport_ioport_write.
