    efi: Add efi_memmap_install() for installing new EFI memory maps · c45f4da3
    Matt Fleming authored
    While efi_memmap_init_{early,late}() exist for architecture code to
    install memory maps from firmware data and for the virtual memory
    regions respectively, drivers don't care which stage of the boot we're
    at and just want to swap the existing memmap for a modified one.
    
    efi_memmap_install() abstracts the details of how the new memory map
    should be mapped and the existing one unmapped.
