    efi: Permit multiple entries in persistent memreserve data structure · 5f0b0ecf
    Ard Biesheuvel authored
    In preparation of updating efi_mem_reserve_persistent() to cause less
    fragmentation when dealing with many persistent reservations, update
    the struct definition and the code that handles it currently so it
    can describe an arbitrary number of reservations using a single linked
    list entry. The actual optimization will be implemented in a subsequent
    patch.
