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).
