Subject: tools/libxc: Fix ARM build broken by XEN_DOMCTL_getvcpuextstate commit
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=15e90cd01f68ff8b23b426e7f91155b81d73db13;p=people%2Froyger%2Fxen.git

tools/libxc: Fix ARM build broken by XEN_DOMCTL_getvcpuextstate commit

The previous "tools/libxc: Exposed XEN_DOMCTL_getvcpuextstate" broke
the ARM build (the hypercall does not have a corresponding DOMCTL
ARM struct). This patch fixes the build by returning -ENODEV for
ARM from xc_vcpu_get_extstate().
