I think Jan wanted a change in commit message. I can commit with this: "Using privcmd_call() for a singleton multicall seems to be wrong, as privcmd_call() is using stac()/clac() to enable hypervisor access to Linux user space. Even if currently not a problem (pv domains can't use SMAP while HVM and PVH domains can't use multicalls) things might change when PVH dom0 support is added to the kernel." -boris _______________________________________________ Xen-devel mailing list [email protected] https://lists.xenproject.org/mailman/listinfo/xen-devel
