Yu Zhao 155f9686bd mm: multi-gen LRU: use {ptep,pmdp}_clear_young_notify() 
[ Upstream commit 1d4832becd ]

When the MM_WALK capability is enabled, memory that is mostly accessed by
a VM appears younger than it really is, therefore this memory will be less
likely to be evicted.  Therefore, the presence of a running VM can
significantly increase swap-outs for non-VM memory, regressing the
performance for the rest of the system.

Fix this regression by always calling {ptep,pmdp}_clear_young_notify()
whenever we clear the young bits on PMDs/PTEs.
