     ("x86-64, mm: Put early page table high") causes a S4
    regression since 2.6.39, namely the machine reboots occasionally at S4
    resume.  It doesn't happen always, overall rate is about 1/20.  But,
    like other bugs, once when this happens, it continues to happen.
    
    This patch fixes the problem by essentially reverting the memory
    assignment in the older way.

    [ We'll hopefully find the real fix, but that's too late for 3.1 now ]
