+Subject: [PATCH] x86: call pit_init for pvh also
+
+During halt of a pvh guest, the guest may do speaker shutdown. This
+results in call to handle_speaker_io in xen. It will hang on the vpit
+spin lock because it has not been initialized.
+Since, pit_init is also called for both pv and hvm, the call is
+moved to a more generic place.

+x86/HVM: restrict HVMOP_set_mem_type
+
+Permitting arbitrary type changes here has the potential of creating
+present P2M (and hence EPT/NPT/IOMMU) entries pointing to an invalid
+MFN (INVALID_MFN truncated to the respective hardware structure field's
+width). This would become a problem the latest when something real sat
+at the end of the physical address space; I'm suspecting though that
+other things might break with such bogus entries.
+
+Along with that drop a bogus (and otherwise becoming stale) log
+message.
+
+Afaict the similar operation in p2m_set_mem_access() is safe.
+
+This is XSA-92.
