| 2017-11-13 | powerpc/lib: Implement UACCESS_FLUSHCACHE API | Oliver O'Halloran | |
| Implement the architecture specific portitions of the UACCESS_FLUSHCACHE API. This provides functions for the copy_user_flushcache iterator that ensure that when the copy is finished the destination buffer contains a copy of the original and that the destination buffer is clean in the processor caches.

| 2017-11-13 | powerpc/lib: Implement PMEM API | Oliver O'Halloran | |
| Implement the architecture specific cache maintence functions that make up the "PMEM API". Currently the writeback and invalidate functions are the same since the function of the DCBST (data cache block store) instruction is typically interpreted as "writeback to the point of coherency" rather than to memory. As a result implementing the API requires a full cache flush rather than just a cache write back. This will probably change in the not-too-distant future.
