mm, /proc/pid/pagemap: fix soft dirty marking for PMD migration entry
When the pagetable 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.
As a result, /proc/pid/pagemap may report incorrect soft dirty information
for PMD migration entries.
