Subject: [PATCH v4 0/1] suspend: make sync() on suspend-to-RAM optional

Based on discussion resulting from...
https://lkml.org/lkml/2015/5/8/82 [PATCH 1/1] suspend: delete sys_sync(),
this patch makes sys_sync() optional, rather than deleting it entirely.

This is an update to the original patch for this issue from Jan, 2014:
patch https://lkml.org/lkml/2014/1/23/73
[PATCH v3] suspend: make sync() on suspend-to-RAM optional

Aside from applying to Linux 4.1, rather than 3.13...
the change is that suspend always checks the flag from the
sysfs attribute before invoking sys_sync(); and the config option
just sets the default value.  Before the config option deleted all code.
Also, the config dependency is corrected, and some varialbes re-named.
