With csum_partial(), which reads all bytes into registers it is easy to also implement csum_partial_copy_nocheck() which copies the buffer while calculating its checksum. For a 512 byte buffer this reduces the runtime by 19%. Compared to the old generic variant (memcpy() + cksm instruction) runtime is reduced by 42%). Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
