x86: KVM guest: Add memory clobber to hypercalls
Hypercalls can modify arbitrary regions of memory. Make sure to indicate this in the clobber list. This fixes a hang when using KVM_GUEST kernel built with GCC 4.3.0. This was originally spotted and analyzed by Marcelo. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
