I've moved functionality of copy_user_64.S and copy_user_nocache_64.S to
copy_user_64.c. Tail handling is now in plain C routine.
copy_user_generic_string, copy_user_generic_unrolled and
__copy_user_nocache were tested by me with a bit modified systemtap's
script which was in attach in my previous letter.

Hi Vitaly, actually I don't see quite benefit from 'wrapping'
assembler code by C. At least it was more readable before. Sorry.
But lets wait for another optinions. Maybe I'm just too hypercritical ;)
A few Cc added.
