hugetlb parallelization depends on PADATA, and PADATA depends on SMP. PADATA consists of two distinct functionality: One part is padata_do_multithreaded which disregards order and simply divides tasks into several groups for parallel execution. Hugetlb init parallelization depends on padata_do_multithreaded. The other part is composed of a set of APIs that, while handling data in an out-of-order parallel manner, can eventually return the data with ordered sequence. Currently Only `crypto/pcrypt.c` use them. All users of PADATA of non-SMP case currently only use padata_do_multithreaded. It is easy to implement a serial one in include/linux/padata.h. And it is not necessary to implement another functionality unless the only user of crypto/pcrypt.c does not depend on SMP in the future.
