Support of lguest?
...ests 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 w...

There is an ongoing work to enable PV TLB flushing for Hyper-V guests:
http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2017-April/104411.html
it utilizes .flush_tlb_others member in pv_mmu_ops.
hopefully, this work will be merged in 4.13.
