Subject: [POWERPC][XEN] Opt out of new libxc domain builder.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~15327^2~3
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=9fb65916be7ce1542a3b4c60286525a3cf66b38c;p=xen.git

[POWERPC][XEN] Opt out of new libxc domain builder.
PowerPC needs more flexibility than the new framework allows.
