[Xen-devel] [v2 1/1] xen, mm: Allow deferred page initialization for xen pv domains

Juergen Gross noticed that commit f7f99100d8d ("mm: stop zeroing memory during allocation in vmemmap") broke XEN PV domains when deferred struct page initialization is enabled. This is because the xen's PagePinned() flag is getting erased from struct pages when they are initialized later in boot.
