You are right, the main data block accesses use memcpy().

The reason I mentioned "direct pointer access" because of the 
`*(__le64 *)` cast used for the bitcount padding in __md5_final() and
hmac_md5_final(). But I agree that mentioning memcpy() is more accurate
for the whole file.

I will update the commit message and send a v3 soon.
