#     Pull x86 fixes from Thomas Gleixner:
#      "A set of three patches to fix the fallout of the newly added split
#       lock detection feature.
#     
#       It addressed the case where a KVM guest triggers a split lock #AC and
#       KVM reinjects it into the guest which is not prepared to handle it.
#     
#       Add proper sanity checks which prevent the unconditional injection
#       into the guest and handles the #AC on the host side in the same way as
#       user space detections are handled. Depending on the detection mode it
#       either warns and disables detection for the task or kills the task if
#       the mode is set to fatal"
