[PATCH 02/21] mm: Use vmf->address instead of of vmf->virtual_address

[Jan Kara <jack@suse.cz>]

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.
