[Xen-devel] [PATCH v2] PVH Dom0 RMRR IOMMU mapping regression fix

2015-09-25 Thread elena . ufimtseva
From: Elena Ufimtseva This patch addresses a regression introduced by commit 5ae03990c120a7b3067a52d9784c9aa72c0705a6 in new set_identity_p2m_entry. RMRRs are not being mapped in IOMMU for PVH Dom0. This causes pages faults and some long 'hang-like' delays during Dom0 PVH boot and device assignm
