Since there are two function features for now, func_bitmap[] has single
one element, which BITMAP_FROM_U64() generating two elements is exceeded.
Change to assign function bitmap barely.
With i386-allmodconfig (a 32 bit system), it throws
>> include/linux/bitmap.h:736:33: warning: excess elements in array initializer
736 | ((unsigned long) ((u64)(n) >> 32))
