[RFC][PATCH -mm 0/2] Detect clock skew during suspend
From: Rafael J. Wysocki

If the CMOS timer is changed when the system is suspended to disk in such a
way that the time during the resume turns out to be earlier than the time
before the suspend, the resume often fails and the system hangs (spins
forever in the idle thread) due to driver problems.
For this reason it seems reasonable to make the timer .resume() routines
detect such situations and prevent them from happening, which is done
in the following two patches for i386 and x86_64.
You never change things by fighting the existing reality.
