From 1a29d85eb0f19b7d8271923d8917d7b4f5540b3e Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 14 Dec 2016 15:07:01 -0800 Subject: mm: use vmf->address instead of of vmf->virtual_address Every single user of vmf->virtual_address typed that entry to unsigned long before doing anything with it so the type of virtual_address does not really provide us any additional safety. Just use masked vmf->address which already has the appropriate type. Link: http://lkml.kernel.org/r/1479460644-25076-3-git-send-email-jack@suse.cz Signed-off-by: Jan Kara Acked-by: Kirill A.
