Linus Torvalds ec6f5e0e5c A set of x86 and membarrier fixes:
- Correct a few problems in the x86 and the generic membarrier
     implementation. Small corrections for assumptions about visibility
     which have turned out not to be true.
 
   - Make the PAT bits for memory encryption correct vs. 4K and 2M/1G page
     table entries as they are at a different location.
 
   - Fix a concurrency issue in the the local bandwidth readout of resource
     control leading to incorrect values
 
   - Fix the ordering of allocating a vector for an interrupt. The order
     missed to respect the provided cpumask when the first attempt of
     allocating node local in the mask fails. It then tries the node instead
     of trying the full provided mask first. This leads to erroneous error
     messages and breaking the (user) supplied affinity request. Reorder it.
 
   - Make the INT3 padding detection in optprobe work correctly.
