Subject[ 034/108] math: Introduce div64_long
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Sasha Levin <levinsasha928@gmail.com>

commit f910381a55cdaa097030291f272f6e6e4380c39a upstream.

Add a div64_long macro which is used to devide a 64bit number by a long (which
can be 4 bytes on 32bit systems and 8 bytes on 64bit systems).
