Linus Torvalds 7b56fbd83e 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.
