Documentation/mm: Drop pxx_mkdevmap() descriptions from page table helpers

[PATCH] Documentation/mm: Drop pxx_mkdevmap() descriptions from page table helpers

Posted by Anshuman Khandual 2 days, 9 hours ago

Remove pxx_mkdevmap() descriptions, as these helper functions have already
been dropped (including DEBUG_VM_PGTABLE test) via the commit d438d2734170
("mm: remove devmap related functions and page table bits").
