    Pull x86 build updates from Thomas Gleixner:
     "Updates for KCOV instrumentation on x86:
    
       - Prevent spurious KCOV coverage in common_interrupt()
    
       - Fixup the KCOV Makefile directive which got stale due to a source
         file rename
    
       - Exclude stack unwinding from KCOV as it creates large amounts of
         uninteresting coverage
    
       - Provide a self test to validate that KCOV coverage of the interrupt
         handling code starts not before preempt count got updated"
