Hello,

cat /proc/<pid>/pagemap 

and 

cat /proc/<pid>/task/<pid>/pagemap

eats up to 100% of CPU while looping forever somewhere. On the other
hand on my old x86 the same commands take well below 1s so I
guess that is the expected behaviour.

PS. I'll be offline till tommorow just in case I was sent some patches to test.
