Linus Torvalds f8818559ca Two fixes for the x86 interrupt code:
- Unbreak the magic 'search the timer interrupt' logic in IO/APIC code
     which got wreckaged when the core interrupt code made the state
     tracking logic stricter. That caused the interrupt line to stay masked
     after switching from IO/APIC to PIC delivery mode, which obviously
     prevents interrupts from being delivered.
 
   - Make run_on_irqstack_code() typesafe. The function argument is a void
     pointer which is then casted to 'void (*fun)(void *). This breaks
     Control Flow Integrity checking in clang. Use proper helper functions
     for the three variants reuqired.
