sparc: copy_from_user() should not return -EFAULT
From: Heiko Carstens <heiko.carstens@de.ibm.com>
Callers of copy_from_user() expect it to return the number of bytes
it could not copy. In no case it is supposed to return -EFAULT.
In case of a detected buffer overflow just return the requested
length. In addition one could think of a memset that would clear
the size of the target object.
