mm/khugepaged: fix the address passed to notifier on testing young
[ Upstream commit 394bfac1c7f7b701c2c93834c5761b9c9ceeebcf ]
Commit 8ee53820edfd ("thp: mmu_notifier_test_young") introduced
mmu_notifier_test_young(), but we are passing the wrong address.
In xxx_scan_pmd(), the actual iteration address is "_address" not
"address". We seem to misuse the variable on the very beginning.
Change it to the right one.
[akpm@linux-foundation.org fix whitespace, per everyone]
