I (as a person who asked the revert) don't mind now to set the
good_end back for 64bit again.  On 3.5/3.6 kernels, there seems more
other places breaking the hibernation on the machines hitting the
problem at that time.  I need to dig deeply, but it's a horrible time-
consuming and unreliable task, thus postponed, so far.


thanks,

Takashi
