    arm64: Don't relocate non-existent initrd · 4ca3bc86
    Mark Rutland authored
    When booting a kernel without an initrd, the kernel reports that it
    moves -1 bytes worth, having gone through the motions with initrd_start
    equal to initrd_end:
        Moving initrd from [4080000000-407fffffff] to [9fff49000-9fff48fff]
    Prevent this by bailing out early when the initrd size is zero (i.e. we
    have no initrd), avoiding the confusing message and other associated
    Fixes: 1570f0d7
     ("arm64: support initrd outside kernel linear map")
