David Hildenbrand 9b071576f8 fs/proc/task_mmu: fix pagemap flags with PMD THP entries on 32bit 
commit 3754137d26 upstream.

Entries (including flags) are u64, even on 32bit.  So right now we are
cutting of the flags on 32bit.  This way, for example the cow selftest
complains about:

  # ./cow
  ...
  Bail Out! read and ioctl return unmatched results for populated: 0 1
