Linus Torvalds 943af0e73a Updates for the X86 APIC:
- Make the quirk for non-maskable MSI interrupts in the affinity setter
     functional again.
 
     It was broken by a MSI core code update, which restructured the code in
     a way that the quirk flag was not longer set correctly.
 
     Trying to restore the core logic caused a deeper inspection and it
     turned out that the extra quirk flag is not required at all because
     it's the inverse of the reservation mode bit, which only can be set
     when the MSI interrupt is maskable.
 
     So the trivial fix is to use the reservation mode check in the affinity
     setter function and remove almost 40 lines of code related to the
     no-mask quirk flag.
 
   - Cure a Kconfig dependency issue which causes compile fails by correcting
     the conditionals in the affected heaer files.
 
   - Clean up coding style in the UV APIC driver.

 - Make the quirk for non-maskable MSI interrupts in the affinity setter
   functional again.

   It was broken by a MSI core code update, which restructured the code
   in a way that the quirk flag was not longer set correctly.

   Trying to restore the core logic caused a deeper inspection and it
   turned out that the extra quirk flag is not required at all because
   it's the inverse of the reservation mode bit, which only can be set
   when the MSI interrupt is maskable.

   So the trivial fix is to use the reservation mode check in the
   affinity setter function and remove almost 40 lines of code related
   to the no-mask quirk flag.

 - Cure a Kconfig dependency issue which causes compile failures by
   correcting the conditionals in the affected header files.

 - Clean up coding style in the UV APIC driver.
