    Subject[PATCH v2 5/5] powerpc/fadump: update documentation about crashkernel parameter reuse
    From
    Date
    As we are reusing crashkernel parameter instead of fadump_reserve_mem
    parameter to specify the memory to reserve for fadump's crash kernel,
    update the documentation accordingly.
