The SDM specifically allows for earlier writes to fully overlapping

would crash it if varying data was written to the same address. Detect
overlaps early, as doing so in hvmemul_{linear,phys}_mmio_access() would

The legacy __xen_guest section doesn't support the PHYS32_ENTRY
elfnote, so it's pointless to attempt to parse the elfnotes from that
section when called from an hvm container.

Hello,
A couple of small fixes for PVH loading. The first one is likely not

addresses must always be used
