Linus,

   # HEAD: 248ed51048c40d36728e70914e38bffd7821da57 x86/nmi: Remove irq_work from the long duration NMI handler

Misc changes:

 - Enhance #GP fault printouts by distinguishing between canonical 
   and non-canonical address faults, and also add KASAN fault decoding.

 - Fix/enhance the x86 NMI handler by putting the duration check into a 
   direct function call instead of an irq_work which we know to be broken 
   in some cases.

 - Clean up do_general_protection() a bit.
