Now, when the page table is walked in the implementation of
/proc/<pid>/pagemap, pmd_soft_dirty() is used for both the PMD huge
page map and the PMD migration entries.  That is wrong,
pmd_swp_soft_dirty() should be used for the PMD migration entries
instead because the different page table entry flag is used.
Otherwise, the soft dirty information in /proc/<pid>/pagemap may be
wrong.
