x86: update populate_extra_pte() and add populate_extra_pmd()
Impact: minor change to populate_extra_pte() and addition of pmd flavor Update populate_extra_pte() to return pointer to the pte_t for the specified address and add populate_extra_pmd() which only populates till the pmd and returns pointer to the pmd entry for the address. For 64bit, pud/pmd/pte fill functions are separated out from set_pte_vaddr[_pud]() and used for set_pte_vaddr[_pud]() and populate_extra_{pte|pmd}(). Signed-off-by: Tejun Heo <tj@kernel.org>
