    arm64: defer __va translation of initrd_start and initrd_end · a89dea58
    Ard Biesheuvel authored
    Before deferring the assignment of memstart_addr in a subsequent patch, to
    the moment where all memory has been discovered and possibly clipped based
    on the size of the linear region and the presence of a mem= command line
    parameter, we need to ensure that memstart_addr is not used to perform __va
    translations before it is assigned.
    
    One such use is in the generic early DT discovery of the initrd location,
    which is recorded as a virtual address in the globals initrd_start and
    initrd_end. So wire up the generic support to declare the initrd addresses,
    and implement it without __va() translations, and perform the translation
    after memstart_addr has been assigned.
