Add support for two new PMEM APIs, copy_from_iter_pmem() and clear_pmem(). copy_from_iter_pmem() is used to copy data from an iterator into a PMEM buffer. clear_pmem() zeros a PMEM memory range. Both of these new APIs must be explicitly ordered using a wmb_pmem() function call and are implemented in such a way that the wmb_pmem() will make the stores to PMEM durable. Because both APIs are unordered they can be called as needed without introducing any unwanted memory barriers.
