Subject: ARM: pgtable: directly pass pgd/pmd/pte to their error functions
X-Git-Tag: firefly_0821_release~7613^2~1828^2~2^3~18
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=69529c0eb76469168f1dd5851f363dbab17ce8fd;p=firefly-linux-kernel-4.4.55.git

ARM: pgtable: directly pass pgd/pmd/pte to their error functions

Rather than passing the pte value to __pte_error, pass the raw pte_t
cookie instead.  Do the same for pmd and pgd functions.
