* Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus reuse the corresponding function "kcalloc".
This issue was detected by using the Coccinelle software.
* Delete the local variable "pd_bitmap_size" which became unnecessary
with this refactoring.
