Subject: x86/EPT: also force EMT re-evaluation if pinned ranges change
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~5121
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=35d1c20b85156eea6b6c3af32b6bad7b9caf6315;p=xen.git

x86/EPT: also force EMT re-evaluation if pinned ranges change

This was inadvertently left out of aa9114ed ("x86/EPT: force
re-evaluation of memory type as necessary"). Note that this
intentionally doesn't use memory_type_changed(): Changes to the pinned
ranges are independent of IOMMU presence, which that function uses to
determine whether to call the underlying p2m_memory_type_changed().
