#     Pull x86 fixes from Thomas Gleixner:
#      "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"
