Subject: [PATCH RFC 1/5] iommu: need_iommu set early
Date: Fri, 13 Feb 2015 13:51:08 -0500	[thread overview]
Message-ID: <20150213185105.GA12720@elena.ufimtseva> (raw)

Set need_iommu for dom0 early so pvh specific functions
in construct_dom0 can pass this check.
See example in p2m-ept.c ept_set_entry.
