commit 3d7177d2700c5466841263d555b43425e60836ce Author: Razvan Cojocaru <rcojocaru@xxxxxxxxxxxxxxx> AuthorDate: Fri Jul 19 16:08:48 2019 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Fri Jul 19 16:08:48 2019 +0200 x86/altp2m: treat view 0 as the hostp2m in p2m_get_mem_access() p2m_set_mem_access() (and other places) treat view 0 as the hostp2m, but p2m_get_mem_access() does not. Correct that inconsistency.
