    Multiplication factor used to calculate the size of placeholder to
    reserve space for kobject metadata hash table. The hash table is
    generated via gperf is highly dependent on the absolute addresses of
    kobjects which might change between prebuilts. To reserve enough
    space for the hash table during final linking passes to keep
    kobjects in same place, the size of reserved space is calculated
    from the first prebuilt plus additional space calculated with
    this percentage (of the kobject data area in first prebuilt).
