Kees Cook 65fe935dd2 x86/KASLR, x86/power: Remove x86 hibernation restrictions 
With the following fix:

  70595b479ce1 ("x86/power/64: Fix crash whan the hibernation code passes control to the image kernel")

... there is no longer a problem with hibernation resuming a
KASLR-booted kernel image, so remove the restriction.
