libelf: make L1_MFN_VALID note known

[PATCH] libelf: make L1_MFN_VALID note known

Posted by Jan Beulich 11 months, 1 week ago

We still don't use it (in the tool stack), and its values (plural) also
aren't fetched correctly, but it is odd to continue to see the
hypervisor log "ELF: note: unknown (0xd)" when loading a Linux Dom0.
