[PATCH 0/3] xen: remove some checks for always present Xen features

[Juergen Gross]

Some features of Xen can be assumed to be always present, so add a
central check to verify this being true and remove the other checks.

Juergen Gross (3):
  xen: check required Xen features
  xen: assume XENFEAT_mmu_pt_update_preserve_ad being set for pv guests
  xen: assume XENFEAT_gnttab_map_avail_bits being set for pv guests
