Barry Song 6434e69814 mm: arm64: fix the out-of-bounds issue in contpte_clear_young_dirty_ptes 
We are passing a huge nr to __clear_young_dirty_ptes() right now.  While
we should pass the number of pages, we are actually passing CONT_PTE_SIZE.
This is causing lots of crashes of MADV_FREE, panic oops could vary
everytime.
