#     
#     Pull x86 fixes from Thomas Gleixner:
#      "Three fixes all related to #DB:
#     
#        - Handle the BTF bit correctly so it doesn't get lost due to a kernel
#          #DB
#     
#        - Only clear and set the virtual DR6 value used by ptrace on user
#          space triggered #DB. A kernel #DB must leave it alone to ensure
#          data consistency for ptrace.
#     
#        - Make the bitmasking of the virtual DR6 storage correct so it does
#          not lose DR_STEP"
