lib: add lib/gcd.c
This patch adds lib/gcd.c which contains a greatest common divider
implementation taken from sound/core/pcm_timer.c
Several usages of this new library function will be sent to subsystem
maintainers.
[akpm@linux-foundation.org: use swap() (pointed out by Joe)]
[akpm@linux-foundation.org: just add gcd.o to obj-y, remove Kconfig changes]
