A few things related to TLB flushing and TLB miss rates
I would like to discuss at LSF/MM:

1) A quick update on IPI-less TLB flushing with
   AMD INVLPGB and Intel RAR, and implications
   for MM synchronization. Probably no real
   discussion needed.

2) A discussion on how we might be able to
   integrate mTHPs into khugepaged, and get
   TLB miss benefits on AMD and ARM CPUs for
   processes where full-size THPs cause too
   much memory waste due to internal fragmentation.

Are there any other related topics we should try to
fit into the same time slot?
