Lguest and Xen pv-guests are the only users of pv_mmu_ops (with the one exception of the .exit_mmap member, which is being used by Xen HVM-guests, too).
As it is possible now to build a kernel without Xen pv-guest support while keeping PVH and PVHVM support, I thought about putting most pv_mmu_ops functions in #ifdef CONFIG_XEN_HAS_PVMMU sections. If there wouldn't be lguest...
So my question: is anybody still using lguest or would like to keep it?
If yes, I'd add CONFIG_PARAVIRT_MMU selected by CONFIG_XEN_PV and CONFIG_LGUEST_GUEST.
If no, I'd remove lguest support and just use CONFIG_XEN_HAS_PVMMU, in case nobody would like me to use CONFIG_PARAVIRT_MMU even if lguest isn't there any more.
