Subject: mm: use vmf->address instead of of vmf->virtual_address
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1a29d85eb0f19;p=linux.git
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.
