On PPC, CR2-CR4 are nonvolatile, thus have to be saved across function calls. We didn't respect that for any architecture until Paul spotted it in his patch for Book3S-HV. This patch saves/restores CR for all KVM capable PPC hosts. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NPaul Mackerras <paulus@samba.org>
